4/4 Help us prepare FFmpeg 9.1: test the release branch and report regressions! FOSDEM 2027's Open Media devroom is accepting talk proposals for Jan 30 in Brussels. Submit by Nov 30: fosdem.org/submit. Thanks to everyone contributing!

3/4 The new side_data bitstream filter removes side data without re-encoding. Whisper JSON now includes the detected language. Fixes cover AAC/Opus seeking, CUVID output corruption, DASH duplicate segments after seeking, and ALSA capture timestamps.

2/4 Faster CUDA frame transfers with pooled, pinned buffers. VMAF analysis can now avoid frame copies. More SIMD work landed too: AArch64 NEON for APV decoding, AVX2 for VVC planar prediction, and RISC-V Vector for scene detection.

1/4 FFmpeg weekly news (Oct 21–27)
New in git master! DTS:X standard presentations now decode to 7.1.4 with height channels. JPEG Multi-Picture Format demuxing exposes Ultra HDR gain maps. HEIF colour and alpha layers are merged automatically.

@smallishzulu Ideally, as many CPU cores as possible, with 4 GB of RAM per core and roughly 100 GB of SSD storage per 8 cores.

Could you or your company sponsor an x86-64 server and hosting for FFmpeg’s CI?

RISC-V, PowerPC or MIPS systems would also be welcome! We currently test these using QEMU on our Ampere ARM server.

Please get in touch!

4/4 Native AMR-NB/WB decoding gained comfort noise support, and AMR-NB gained concealment for lost speech frames. FATE CI now has a native LoongArch64 runner on a 64-core Loongson system. Thanks to everyone contributing code, reviews, tests and hardware!

3/4 Large HLS playlists parse faster. HTTP/RTSP gained SHA-256 Digest auth for ONVIF cameras that need it. HEVC deblocking offsets, DNxHR HQX weights and Ogg Vorbis seeking were fixed, plus HTTP cookie scoping, security and robustness fixes. Please test and report regressions!

2/4 scale_cuda now converts between RGB and YUV while resizing on the GPU. The ONNX Runtime backend gained D3D12/DirectML zero-copy processing, keeping compatible decode/inference/encode pipelines in GPU memory. The bitpacked decoder gained x86 and AArch64 SIMD.

1/4 FFmpeg weekly news (Oct 14–20): ffplay gained a searchable file browser. Press o to browse folders, type to filter names, and click or press Enter to play. Infinity IMM6 decoding and LCEVC muxing in MPEG-TS landed too. New in git master!

Linus Torvalds to the anti-AI crowd: stop using compilers if you want to prove they’re REAL programmers. LOL.

“you had better not use an editor to write that commit message either.

The kind of expectations *I* have is that people do their best and I expect people to understand ut that understanding has very little to do with what tools they use.

And quite honestly, in my experience, the people I respect and call intelligent are not the ones that shy away from using new and interesting tools.”

How can FFmpeg developers participate remotely in the FFmpeg meeting organized by Jean-Baptiste Kempf at VDD 2026? It’s happening now. Is there a link to join?

4/4 Welcome Marcos Ashton Iglesias as maintainer of the libavutil tests he wrote! Several previously offline FATE clients are reporting again. Thanks to everyone running test machines and keeping FFmpeg working across platforms!

3/4 HTTP range/EOF handling and HLS byte-range playback were fixed. Security and robustness fixes landed, including fixes from OSS-Fuzz reports and follow-up investigations into issues found by Fairy's automated code reviews. Please test and report regressions!

2/4 ffplay's chapter list gained faster rendering and more responsive input. VC-1 gained SSE2/AVX2 inverse transforms. LoongArch LSX now accelerates fast bilinear scaling and NV12/NV21-to-RGB conversion. A Windows handle protocol landed too.

1/4 FFmpeg weekly news (Oct 7–13): Panasonic RW2 RAW decoding (RawFormat 8) landed. HEIF now exposes gain maps, including Apple's. A new libfdk-xhe-aac wrapper brings xHE-AAC encoding, initially single-pass. New in git master!

4/4 Welcome Kacper Michajłow as maintainer of FFmpeg's libcurl HTTP backend! Filter graphs now negotiate chroma location and convert it to match encoder requirements. Please test git master and report regressions!

3/4 The native AAC encoder gained improved VBR, a new average bitrate mode (-aac_rc abr) and 5.1.6/7.1.6 support. A Citrix ADPCM decoder landed too. AArch64 gained NEON iMDCT/FFT and 10/12-bit HEVC/VVC SAO optimizations. H.264 weighted prediction SIMD fixes also landed.

2/4 Vulkan FFV1: about 5x faster encoding and 3.5x faster decoding in a 6464x4852 16-bit RGB benchmark (1024 slices, RX 6900 XT, data in VRAM). HEVC gained parallel tile decoding under slice threading, with reported speedups up to 3.5x at 8 threads on tiled streams.

1/4 FFmpeg weekly news (Sep 30–Oct 6): JPEG Ultra HDR output landed, with a new gainmap filter and JPEG-MPF muxer. The v360_vulkan filter now accepts GoPro Max 360° input. New in git master!
