Changelog

What’s new across freemkv — the command line, the desktop app, and the freemkv-library server (autorip before 1.8.0) — newest first. Every release ships all three together under one version number.

Release downloads are also available on GitHub: freemkv releases.

1.8.5

2026-10-20

Fixed

Library: a finished rip muxes again. Rips saved with Keep ISO off could stop at “reading the saved disc image failed”; those saved rips now finish without the disc.
USB drives: a drive that hits a read error is left alone to recover instead of being sent more commands until it stops responding, and its tray always unlocks, so Eject works without power-cycling the drive.
Library: ejecting and re-inserting a disc after a drive error or a Stop starts it again. A disc that already finished is never ripped twice.
Library: errors say what went wrong, with an error code, instead of “an unexpected error occurred”.
Security: improve protection when handling ZIP archives.

1.8.4

2026-10-15

Added

Presentation language. When a disc carries the movie in several language versions, pick yours: --presentation-language de, Settings ▸ Selection in the app, or the Library’s settings.
Library: Change match corrects what an ISO is, remuxes it under the right names and removes the old files it made. Files you changed are never touched.
Library: TV discs remux into episodes in your TV folder, as a rip does.
Library: Reboot library and Clear staging on the System page.

Changed

App: audio and subtitle choices are remembered for the next disc (Settings ▸ Selection turns this off), and Settings save without freezing the window.
Library: TV episodes come from the disc’s own episode list; a disc whose episodes can’t be told apart waits in Review and says what to do.
Library: deliveries continue after a restart and retry a failed copy twice before waiting for Retry. Title corrections stay with the disc.
Library: allow 130 s to stop. On macOS re-run macos/install-library-service.sh (Reboot needs it); in Docker set stop_grace_period: 130s.

Fixed

Library: an unmounted network share no longer gets folders created on the local disk.
Library: a slow NAS keeps receiving deliveries, and the server always stops when asked, even with a share hung.
Library: the remux queue survives a share that can’t be read for a moment.

1.8.3

2026-10-09

Added

Pioneer runtime unlocking (beta). freemkv automatically unlocks supported Pioneer and Pioneer-based drives in RAM, without flashing firmware. The CLI, app, and Library use the same unlock flow and can read the disc Volume ID. Speed and region controls are not yet available for Pioneer drives.

1.8.2

2026-10-08

Changed

Faster key lookup. Discs are keyed from the CPS units they declare instead of reading every stream file: a 46-file UHD over USB goes from about 95 s to under 2 s. The live scan also reads less of the disc.
App: Start reuses the drive, scan and keys from Open, about 8 s less per rip.
Library: MKV rips that don’t keep the ISO read only the titles they mux, not the whole disc.

Fixed

Library: Stop no longer rescans the disc it stopped, a network share that stops responding no longer hangs startup, and key-service retries no longer reread the disc.
Windows: a bare drive letter (E) opens that drive. Linux: a bare node name (sg3, sr0) opens it under /dev.
The Library server image reports its real rip-library version (1.8.1’s image showed 1.8.0; the code was the same).

1.8.1

2026-10-07

New

Connect to Remote Library. Settings can connect other freemkv Libraries: their drives appear beside yours with machine labels, live progress, controls and logs, and shared muxing, moving and title-review panels. Jobs and output stay on the machine that owns them.
ARM builds: Windows on ARM, 64-bit ARM Linux (.deb and AppImage) and 32-bit Raspberry Pi OS (CLI), plus a multi-arch server image.
Webhooks support custom authentication headers, including Jellyfin, with a Test button.

Changed

Drive lists show every optical drive. Windows no longer misses drives numbered above CdRom15 (common with USB drives), Linux lists drives when the sg module is not loaded, and macOS no longer stops at eight drives.
macOS: the app ships as a .zip instead of a .dmg (allow its first launch under Privacy & Security).
File moves show a recent transfer speed and a steadier ETA.

Fixed

A stopped disc no longer restarts on its own, and the Library stays responsive through storage and connection stalls.
macOS: one drive no longer appears twice while it is being ripped.
Renesas drives: more reliable unlocking.

1.8.0

2026-10-05

New

freemkv-library replaces autorip. The ripping server is now part of freemkv, with a Library tab for remuxing and checking your movies. Existing autorip installs keep pulling the same image name and load their settings unchanged.
Separate app and CLI builds on every OS. Windows gets a per-user installer, Linux a split .deb, a Flatpak and a confined Snap, and Homebrew a freemkv cask and a freemkv-cli formula.
DVD: chapter names where the disc has them, the disc’s region, stream labels such as commentary, and forced subtitles detected.
HD DVD: AACS-encrypted HD DVDs decrypt with a known key.
UHD: HDR10 mastering data is kept when content light level is absent; HDR10+ and Dolby Vision tracks are labelled correctly.

Changed

An ISO is decrypted unless you ask for raw, on every front end, and a stopped multi-pass recovery resumes where it stopped.
The app’s title list shows each title’s length and size in their own columns, with its chapters under a collapsed row.
Ripped files are named from the disc’s title.

Fixed

TrueHD 7.1 and Atmos tracks are labelled correctly.
A DVD ripped to a folder is descrambled.
An encrypted Blu-ray folder rips like its ISO.
The server no longer loses work when a network share drops: rips and moves wait for it instead of writing to local disk.

freemkv-library replaces autorip

The autorip service is now freemkv-library, the freemkv web server. This is a rebrand: behaviour and settings are unchanged, so an existing install just pulls the new image.
The image is ghcr.io/freemkv/freemkv-library (:latest and :vX.Y.Z). The same image is still published as ghcr.io/freemkv/autorip, and it still answers to the autorip command.
It reads your existing /config/settings.json unchanged, and the AUTORIP_* environment variable names are unchanged.
New web UI.
New Library tab: lists your MKVs and ISOs side by side, shows which freemkv version muxed each MKV, remuxes out-of-date titles from their ISO, and audits the library.
freemkv-library ships only as a Docker image; there are no native binary downloads or Homebrew formula for it.

1.7.7

2026-09-26

Fixed

Forced PGS subtitles now disappear when their display period ends, instead of remaining until the next subtitle.
Preserve PGS clear-event timestamps when remuxing, addressing the reproduced issue in #52. A fresh rip is needed to confirm the fix on affected discs.
Improve audio frame handling and preserve opening audio and MKV timing metadata.
Keep the Linux desktop interface responsive while opening and scanning sources.

Linux packages

Add a native .deb containing the desktop app and CLI for Ubuntu 24.04 and Linux Mint 22.
Publish direct .flatpak downloads on GitHub Releases, independently of Flathub acceptance.
Add installation instructions and download links for both formats.

1.7.6

2026-09-26

Added

Linux desktop app (BETA). freemkv now has a native GTK4 + libadwaita desktop app on Linux, with the same features as the macOS and Windows apps: pick a drive, file or folder, tick titles and tracks, choose a format, press Rip. Same core on all three, so a fix lands everywhere at once. A Flatpak (org.freemkv.FreeMKV) and an AppImage are on the way; Flathub submission follows this release.
Rip-finished notification on macOS, Windows and Linux. Click it to open the output folder. Turn it off in Settings if you don’t want it (default: on).

Fixed

freemkv info accepts --log-level, and --log-file without a path no longer eats the next option.
No more false “MP4 can’t hold MPEG-2” warning after switching discs.
The log pane stays fast during long rips on macOS and Windows.
On Linux the default output folder is your real Videos folder, even if it was moved or has a translated name.
info --share explains why the disc structure could not be captured.

Autorip

Re-inserting a disc after an interrupted rip (crash, power loss, eject) picks up where it left off instead of restarting from title 1.
The UI shows how much staging space the selected titles will need before the rip starts, and a resume no longer fails the space check by ignoring what is already staged.
Key-service failures get their own messages: an outage, a definitive “no key for this disc”, over quota and unlicensed are told apart, and only the outcomes where retrying can help are retried. The tracker link in the AACS-failure message is clickable.

1.7.5

2026-09-23

Fixes

Drives running freemkv firmware 0.9.0 unlock again. Firmware 0.9.0 consolidates two separate drive controls — one for the authentication handshake, one for in-transit encryption — into a single control, because the second one turned out to do nothing on its own. The unlocker now sets the one control instead of the two that no longer exist. Without this, a drive on 0.9.0 firmware would fall back to the slower online-key route. Drives on older firmware are unaffected.

If you flash firmware

freemkv-firmware 0.9.0 is a separate release and needs this version of freemkv to drive it. It fixes a bug where a drive could come up with in-transit encryption disabled at power-on even when it was configured to leave it on, and a second one where changing the encryption setting with no disc loaded would stop the drive answering further freemkv commands until it was power-cycled.

1.7.4

2026-09-21

Fixes

Correct main title on BD-J / Java-menu Blu-rays. Some discs that drive their menu with BD-J (a Java menu) were having the wrong title picked. 1.7.4 walks the disc’s menu, adds a chapter-completeness failsafe, and breaks ties by stream richness, so autorip and the CLI pick the real main feature — keeping the Dolby Vision layer and all subtitle tracks instead of a lesser sibling.
PGS subtitle “Timestamps are unset” muxing error fixed. Blu-ray (PGS) subtitles now carry a proper per-block duration, so muxing no longer fails with the “Timestamps are unset” error.
Clearer “no key in keydb” messaging. A missing key now tells you whether the disc simply isn’t in the database or is listed but still needs a VID to be usable, and the lookup now shows the disc hash so a report can be matched up.

Improved

More resilient keydb downloading: a slow-but-progressing download is no longer killed by an absolute deadline (rolling-idle timeout).

1.7.3

2026-09-19

Fixes

Correct main title on multi-angle / seamless-branch UHD discs. Some 4K Blu-rays that use multiple angles for the main feature were having the wrong title (or no title) picked, because the disc’s stream table was read at the wrong place for a multi-angle playlist. 1.7.3 locates it correctly, so autorip and the CLI pick the real main feature.

New

freemkv info … --share captures a disc’s structure for bug reports. If a disc still picks the wrong title, --share bundles just the small BDMV/VIDEO_TS metadata (playlists, clip info — a few hundred KB, no video/audio and no keys) so the problem can be reproduced without sending the whole disc. Works on a drive, an ISO, or a folder. See https://freemkv.org/docs/troubleshooting/#sharing-a-profile-share

1.7.2

2026-09-18

Fixes

freemkv firmware drives now unlock and decrypt correctly. Drives running freemkv firmware were not having all of their features applied during a rip — in particular, sample data sent for key recovery could still be bus-encrypted, and some drives fell back to the online/AACS path instead of unlocking directly. 1.7.2 applies every firmware feature the way it should, so freemkv firmware drives unlock cleanly and hand off clean, decrypted data.
More reliable disc size detection. Hardened how we read a disc’s capacity so a drive that briefly reports the wrong size no longer produces an empty or truncated rip.

New

Use freemkv firmware with 1.7.2. This release ships the updated firmware modify support, so drives you flash with freemkv firmware work end-to-end with the 1.7.2 app.

1.7.1

2026-09-14

Fixes

LibreDrive unlocking restored. A regression in 1.7.0 stopped some drives from unlocking — those that report a specific model name our catalogue lists more generically (for example the LG BU40N). 1.7.1 matches them correctly again, so LibreDrive-based Blu-ray and UHD ripping works on these drives as it did before.

1.7.0

2026-09-06

New — early access (beta)

Renesas drive unlocking. freemkv can now open selected Renesas / Pioneer drives for reading, alongside the existing routes. This is early and unvalidated — if you have one of these drives, give it a try and tell us how it goes.
freemkv firmware. freemkv can also read drives running freemkv’s own firmware. The companion tools that flash and modify that firmware — freemkv-flash and freemkv-fw, each with a command line and a desktop app — are at freemkv.org/firmware.

Fixes

An MP4/MOV file that uses 64-bit box sizes could be read only part-way through; it is now walked in full.
The right drive profile is now chosen for a drive whose exact model isn’t in our catalogue but reports a valid product id — previously it could be matched to a sibling model, and that model’s microcode.

Security

Fixed a low-severity memory-safety issue in the internal sector-prefetch buffer pool (advisory GHSA-j8ww-f5fg-9pmh). No shipped feature could trigger it.

1.6.14

2026-08-31

Fixes

The web dashboard no longer briefly hangs while scanning a large library.

1.6.13

2026-08-28

Drive support

freemkv info disc:// --share now captures a few additional drive responses on Pioneer / Renesas drives. If you have one of these drives and would like to help us add support for it, re-run the command and share the profile it prints.

1.6.12

2026-08-27

Ripping

macOS: fixed a case where the disc could unmount partway through a rip — seen as E1000 (“Write failed”), with the disc then re-mounting on its own. freemkv now holds an exclusive claim on the drive for the whole rip, so the system no longer takes it back mid-read.
If the disc or drive state changes underneath a rip, freemkv now reacquires the drive and restarts the pass instead of failing the read.

1.6.11

2026-08-26

Ripping

More reliable main-feature detection on Blu-ray and DVD discs: freemkv now follows the disc’s own on-disc navigation to find the main feature, instead of guessing from title length alone, so it’s far less likely to be fooled by a decoy title.

Autorip

Fixed a rare case where a disc could get stuck endlessly retrying a failed mux step instead of being marked as failed and moving on.

1.6.10

2026-08-23

Ripping

Fixed rare Dolby TrueHD / Atmos audio errors on discs that carry a gap in their transport stream: the ripped track could make some players report audio glitches around the affected moment, or an integrity checker flag the file as corrupt. freemkv now resynchronises the audio cleanly across such gaps, so the muxed file plays back and verifies without the errors. (The gapped instant is in the source and can’t be recovered, but the file is no longer flagged corrupt.)

1.6.9

2026-08-22

Autorip

Automatic per-episode TV ripping — insert a series disc and every episode comes out as its own Show S01E02 - Title.mkv, filed into TV/Show (Year)/Season NN/, with no operator step. Episodes are matched to TMDB and numbered correctly even when a season is split across several discs.
Manual Rename — file a disc under any exact name you type, with no TMDB match required, so an alternate cut (e.g. a “Super Duper Cut”) no longer collides with an already-ripped title.

1.6.8

2026-08-21

Autorip

Webhooks now fire per pipeline stage — Rip (the disc is read and the drive is free), Mux (the MKV is produced), and Move (the file lands in your library) — each independently selectable per hook
The Rip notification now arrives the moment the drive is free, so you can load the next disc while the mux keeps running in the background — instead of only arriving once the mux had finished
The Ripper tab’s “still working in the background” banner now also shows while a file is being moved, not just while muxing

1.6.7

2026-08-21

Autorip

Each webhook can now choose whether it fires on rip complete, move complete, or both
The Move card shows a separate progress bar for every moved file — the movie and its kept ISO each get their own
A title that is being moved is no longer listed twice in the Move card
A failed webhook now logs the real reason (e.g. the connection was reset) instead of a generic “uncategorized error”

1.6.6

2026-08-20

Autorip

Webhooks can now point at your LAN (e.g. a Home Assistant automation) — the private-address guard no longer blocks them

1.6.5

2026-08-20

Autorip

Mobile-friendly dashboard
Save the intermediate or whole-disc ISO to a dedicated ISO folder
Rips made without a TMDB key now land in your movie library

1.6.4

2026-08-15

Autorip

A stalled upload can no longer restart the service mid-rip
The main log no longer grows for the life of the container
A redirected webhook is no longer reported as delivered

Command line & desktop app

A freshly opened disc now shows the title you want, not the bottom of the list
Unticking a track under one title no longer leaves it ripping under another
A damaged-disc recovery can no longer write the wrong film under the right name
Decrypting an image over its own source file is now refused
A video-only title’s checkbox no longer shows and toggles backwards
The key-database download no longer hangs forever on a slow mirror
A fresh install can now rip from a drive or ISO out of the box
The window no longer freezes while probing the drive at launch

Discs & decoding

Fixes a Blu-ray/UHD title whose sound ran on about half a minute past the picture
A multi-title-set DVD can no longer be decrypted under the wrong key
A disc with an all-zero language code no longer aborts track export
A power-cycle-recoverable drive wedge is no longer written off as permanent data loss
A rip cancelled seconds in no longer reports a healthy disc as seriously damaged

1.6.3

2026-08-10

Command line & desktop app

Install with Homebrew on macOS and Linux (brew install freemkv/tap/freemkv)
Asking for forced subtitles in one language no longer ticks several others
The log can now be shown and hidden while a rip is running
Hiding the log no longer leaves a blank band across the window (macOS)

Fixes NTSC DVD chapter marks and durations that ran about 0.1% short

1.6.0

2026-08-03

Command line & desktop app

freemkv for Mac — a native desktop app: open a disc or image, tick titles and tracks, press Rip
One freemkv binary is now both the command line and the desktop app
Pick audio/subtitle tracks by language (-a / -s)
True multi-pass damaged-disc recovery in the desktop app

A corrupt mkv:// input now errors instead of returning an empty result

1.5.2

2026-07-22

Command line

The unlock report now labels DVDs as “DVD” instead of “CSS”.

Discs & decoding

TrueHD 7.1/Atmos audio is now corrected on AACS-encrypted Blu-ray and UHD discs, instead of falling back to a 5.1 channel count.
AACS 2.1 menu and extras titles that carry no forensic key now rip using the disc’s base key instead of failing.
Multi-key AACS discs now decrypt each clip with its own key, fixing garbled secondary content.
CSS DVDs no longer produce garbled output; every read now uses the correct per-title key.
Scanning a CSS DVD is much faster — about 25 seconds down to about 6.
A disc that can’t be decrypted now stops with an error instead of writing scrambled data or a truncated block out as a broken file.

1.5.1

2026-07-20

Discs & decoding

TrueHD audio was being silently dropped entirely (and could send some players into a runaway memory spiral); it is fixed. Titles ripped while this was broken need a re-rip.
HD DVD AACS keys are now found whatever directory and filename layout the studio used, not just the most common one.
HD DVD discs with more than one protected title now decrypt all of them instead of just the first.
A disc with marginal, barely-readable spots no longer “rips clean” while hiding corrupted data; those spots are now retried and either recover or are reported as an honest gap.

1.5.0

2026-07-19

Command line

New MP4 output — rip straight to a play-everywhere MP4 with no external transcoder. It’s a compatibility export: tracks MP4 can’t hold (TrueHD, LPCM, bitmap subtitles) are listed and excluded rather than silently dropped.
MP4 can now also be used as a source, for a frame-exact round trip into any other format.
Five new single-part exports: video-only, audio-only, and subtitle-only files, a chapter-markers sidecar, and a full title-structure JSON.

Discs & decoding

Forced subtitles can now be detected from the subtitle content itself, so discs that don’t flag them are handled correctly too.
Corrupt audio frames are now dropped cleanly instead of muxed as glitches, across every audio format, while keeping picture and sound in sync.
TrueHD: brief bursts of stream damage no longer throw away a whole track or shift the audio that follows.
Uncommon free-format MP2/MP3 audio is no longer rejected.

1.4.5

2026-07-18

Discs & decoding

AACS 2.1 forensic discs now produce a clean stream, instead of visible playback glitches and dropped frames around each forensic segment.
A decryption key written with an uppercase prefix is no longer silently ignored.

Security

Decryption keys can no longer end up in a log or crash message.

1.4.4

2026-07-17

Discs & decoding

Online key lookups were sometimes skipped before ever reaching the key service; they now run reliably.

1.4.3

2026-07-17

Discs & decoding

The online key service can now return a full forensic key set as well as a single key.

1.4.2

2026-07-15

Discs & decoding

Fixed a bug where content that decrypted fine but didn’t parse as clean video could blank out good picture and repeatedly re-query the key server for a key it already had.

1.4.1

2026-07-14

Discs & decoding

A single bad packet no longer causes a whole block of good video to be discarded.
A track is now flagged 3D only when that information is actually present on the disc.

1.4.0

2026-07-13

Discs & decoding

Blu-ray 3D (MVC) support — a 3D disc rips to a single MKV that preserves both eyes, with no transcoding or side-by-side conversion. The 2D view is byte-identical to a standard 2D rip.

1.3.2

2026-07-10

Discs & decoding

Better recognition of AACS 2.1 forensic-variant discs, ahead of full decryption support.

1.3.1

2026-07-10

Discs & decoding

HD-DVD titles now use the disc’s own playlist for clip order, duration, name, and chapters instead of guessing from filenames, with the old guess kept as a fallback.

Project

Relicensed to the MIT License from 1.3.1 onward (releases through 1.3.0 remain AGPL-3.0).

1.3.0

2026-07-08

Discs & decoding

AACS 2.1 (FMTS) discs are now recognized as their own format and mostly rip, with only the not-yet-supported forensic segments skipped.
Initial HD-DVD support — HD-DVD is detected as its own format and its video and audio rip through the pipeline. Title composition is still a best guess, so a disc that authors two features under one naming scheme may show as a single title.
Older program-stream video (H.264, VC-1, HEVC on HD-DVD and older discs) now gets correct per-frame timestamps.
The main feature is now picked by physical size, so a disc that splits its feature across many small clips is no longer passed over for a shorter composite.
More reliable track-label detection across differing disc authoring, with a last-resort fallback that reads menu-artwork languages.

Security

Disc metadata (title, labels) is now cleaned before it’s printed, so a malicious disc can’t inject terminal control sequences.

1.2.2

2026-07-04

Discs & decoding

AACS 2.1 Media Key Variant support now matches real variant discs.
Fixed AACS device-key fallback that had been silently broken.
Resolving the AACS processing key on UHD discs is roughly 15× faster — about 37 seconds down to about 2.4.

1.2.1

2026-07-02

Discs & decoding

DVD DTS audio no longer muxes with timestamps that some strict players rejected.

1.2.0

2026-07-01

Command line

Progress now includes a per-range breakdown of damage — chapter, movie-time offset, and at-risk time.
A rip now reports which unlock mechanisms (firmware, AACS, CSS) actually ran.

Discs & decoding

Damaged-disc recovery now tries a wider set of techniques, re-ranked per disc by what’s actually working.
Added an optional recovery mode for discs with heavily hardened damage.
A new “fast capture” pass grabs every readable block first, before falling back to slower per-sector recovery.
A block that genuinely can’t be decrypted is now concealed cleanly so the file still plays, instead of writing broken data.
Recovery can no longer hang forever on a wedged drive.
Every DVD now rips at full speed — a drive speed-up had been skipped for DVDs.
DVD DTS/LPCM tracks that weren’t the disc’s first audio no longer come out silent.
Real video is no longer dropped at the end of an encrypted fragment.
Audio no longer corrupts across a stream discontinuity.
Online key lookups for disc images now send the required data, instead of every request being rejected.
Discs using an older AACS version now read their keys correctly.
Fixed a possible crash on a corrupt disc.

1.1.0

2026-06-28

Command line

Every user-facing error now shows an error code, with a new Error Codes reference page listing the cause and next steps for each, in all supported languages.
Windows-reserved filenames on a disc are now safely renamed on extraction instead of aborting.

Discs & decoding

Every decrypted unit is now verified before it’s accepted, catching a class of silent bad read.
Stricter AACS acceptance, so a wrong key can’t coincidentally pass and quietly corrupt output.
DVD rips now start on the actual movie instead of the disc’s menu screens.
Multi-part files in folder extraction no longer have later parts written as empty holes.
Fixed a rare false frame-split in DTS-HD Master Audio.
Fixed TrueHD timestamps stepping backward under certain source timing.
Fixed several container-metadata issues (color info, subtitle wipe, sidecar alignment).

Security

Fixed a misread flag that could defeat a safety check meant to refuse decrypting encrypted-bus content with no bus key.

1.0.0

2026-06-24

First stable release.

A command-line tool that rips optical discs to MKV.
Decrypts DVDs (CSS — including keyless recovery, with no key database needed), Blu-ray, and UHD (AACS 1.0/2.0).
Keys are resolved from a local key database and verified against real disc content before use.
Multipass recovery reads through bad sectors on scratched or damaged discs, and can resume after an interruption.
MKV output from a fast threaded pipeline, with support for HEVC, H.264, VC-1, MPEG-2, TrueHD, DTS(-HD), and PGS subtitles.
Can also write a decrypted file tree or a whole-disc ISO image.
Works across Windows, macOS, and Linux.
