Important

We recommend running CasparCG 2.5 on CPUs which support AVX2. Officially Chrome claims to require AVX2, and it is required for some of our in-progress HDR support.
Intel CPUs based on Haswell or later support this, which were first released to consumers in 2013, or 2014 for servers.

Starting with CasparCG 2.6, this will become a requirement.

Make sure to install the latest MSVC runtime, the compiler update requires a newer version than 2.4 https://aka.ms/vc14/vc_redist.x64.exe

• Update ffmpeg to 7.0
• Reimplement mixer transforms, to handle routes correctly
• Support more pixel formats from ffmpeg, to preserve colour accuracy better
• Support running on headless linux
• Transitions: Additional behaviours

Fixes

• Build with boost 1.85/1.86/1.87/1.88
• Build with ffmpeg 7.1

• Routed channels not compositing correctly when channel used a MIXER KEY
• Handle audio for fractional framerates properly
• Gracefully exit on SIGINT and SIGTERM

Full Changelog: v2.4.3-stable...v2.5.0-stable

A new major release, FFmpeg 8.0 "Huffman", is now available for download. Thanks to several delays, and modernization of our entire infrastructure, this release ended up being one of our largest releases to date. In short, its new features are:

• Native decoders: APV, ProRes RAW, RealVideo 6.0, Sanyo LD-ADPCM, G.728
• VVC decoder improvements: IBC, ACT, Palette Mode
• Vulkan compute-based codecs: FFv1 (encode and decode), ProRes RAW (decode only)
• Hardware accelerated decoding: Vulkan VP9, VAAPI VVC, OpenHarmony H264/5
• Hardware accelerated encoding: Vulkan AV1, OpenHarmony H264/5
• Formats: MCC, G.728, Whip, APV
• Filters: colordetect, pad_cuda, scale_d3d11, Whisper, and others

A new class of decoders and encoders based on pure Vulkan compute implementation have been added. Vulkan is a cross-platform, open standard set of APIs that allows programs to use GPU hardware in various ways, from drawing on screen, to doing calculations, to decoding video via custom hardware accelerators. Rather than using a custom hardware accelerator present, these codecs are based on compute shaders, and work on any implementation of Vulkan 1.3.
Decoders use the same hwaccel API and commands, so users do not need to do anything special to enable them, as enabling Vulkan decoding is sufficient to use them.
Encoders, like our hardware accelerated encoders, require specifying a new encoder (ffv1_vulkan). Currently, the only codecs supported are: FFv1 (encoding and decoding) and ProRes RAW (decode only). ProRes (encode+decode) and VC-2 (encode+decode) implementations are complete and currently in review, to be merged soon and available with the next minor release.
Only codecs specifically designed for parallelized decoding can be implemented in such a way, with more mainstream codecs not being planned for support.
Depending on the hardware, these new codecs can provide very significant speedups, and open up possibilities to work with them for situations like non-linear video editors and lossless screen recording/streaming, so we are excited to learn what our downstream users can make with them.

The project has recently started to modernize its infrastructure. Our mailing list servers have been fully upgraded, and we have recently started to accept contributions via a new forge, available on code.ffmpeg.org, running a Forgejo instance.

As usual, we recommend that users, distributors, and system integrators to upgrade unless they use current git master.

This is the first patch release for 2.3.

Primarily this contains a crtical fix to provide support for flash templates to be used after the flash player EOL at the end of 2020.
For more information on the issue see: #1352

Thanks to @silid for developing the fix and @didikunz for documenting the process and being a key member of chasing for these releases to be made

Changes

Producers

Fixes

• Flash: Use proper file urls when loading templates, to allow it to work after Flash Player EOL
• FFmpeg: Various HTTP playback improvements

This is a critical fix for the 2.0.7 release, to provide support for flash templates to be used after the flash player EOL at the end of 2020

For more information on the issue see: #1352

This has been built to be as close as possible to the previous 2.0.7 release, to minimise any risk of deployment.

FFmpeg 7.1 "Péter", a new major release, is now available! A full list of changes can be found in the release changelog.

The more important highlights of the release are that the VVC decoder, merged as experimental in version 7.0, has had enough time to mature and be optimized enough to be declared as stable. The codec is starting to gain traction with broadcast standardization bodies.
Support has been added for a native AAC USAC (part of the xHE-AAC coding system) decoder, with the format starting to be adopted by streaming websites, due to its extensive volume normalization metadata.
MV-HEVC decoding is now supported. This is a stereoscopic coding tool that begun to be shipped and generated by recent phones and VR headsets.
LC-EVC decoding, an enhancement metadata layer to attempt to improve the quality of codecs, is now supported via an external library.

Support for Vulkan encoding, with H264 and HEVC was merged. This finally allows fully Vulkan-based decode-filter-encode pipelines, by having a sink for Vulkan frames, other than downloading or displaying them. The encoders have feature-parity with their VAAPI implementation counterparts. Khronos has announced that support for AV1 encoding is also coming soon to Vulkan, and FFmpeg is aiming to have day-one support.

In addition to the above, this release has had a lot of important internal work done. By far, the standout internally are the improvements made for full-range images. Previously, color range data had two paths, no negotiation, and was unreliably forwarded to filters, encoders, muxers. Work on cleaning the system up started more than 10 years ago, however this stalled due to how fragile the system was, and that breaking behaviour would be unacceptable. The new system fixes this, so now color range is forwarded correctly and consistently everywhere needed, and also laid the path for more advanced forms of negotiation.
Cropping metadata is now supported with Matroska and MP4 formats. This metadata is important not only for archival, but also with AV1, as hardware encoders require its signalling due to the codec not natively supporting one.

As usual, we recommend that users, distributors, and system integrators to upgrade unless they use current git master.

The number of issues FFmpeg has in Coverity (a static analyzer) is now lower than it has been since 2016. Our defect density is less than one 30th of the average in OSS with over a million code lines. All this was possible thanks to a grant from the Sovereign Tech Fund.

FFmpeg now implements a native xHE-AAC decoder. Currently, streams without (e)SBR, USAC or MPEG-H Surround are supported, which means the majority of xHE-AAC streams in use should work. Support for USAC and (e)SBR is coming soon. Work is also ongoing to improve its stability and compatibility. During the process we found several specification issues, which were then submitted back to the authors for discussion and potential inclusion in a future errata.

The FFmpeg community is excited to announce that Germany's Sovereign Tech Fund has become its first governmental sponsor. Their support will help sustain the maintainance of the FFmpeg project, a critical open-source software multimedia component essential to bringing audio and video to billions around the world everyday.

A new major release, FFmpeg 7.0 "Dijkstra", is now available for download. The most noteworthy changes for most users are a native VVC decoder (currently experimental, until more fuzzing is done), IAMF support, or a multi-threaded ffmpeg CLI tool.

This release is not backwards compatible, removing APIs deprecated before 6.0. The biggest change for most library callers will be the removal of the old bitmask-based channel layout API, replaced by the AVChannelLayout API allowing such features as custom channel ordering, or Ambisonics. Certain deprecated ffmpeg CLI options were also removed, and a C11-compliant compiler is now required to build the code.

As usual, there is also a number of new supported formats and codecs, new filters, APIs, and countless smaller features and bugfixes. Compared to 6.1, the git repository contains almost ∼2000 new commits by ∼100 authors, touching >100000 lines in ∼2000 files — thanks to everyone who contributed. See the Changelog, APIchanges, and the git log for more comprehensive lists of changes.
