November 10th, 2023, FFmpeg 6.1 "Heaviside"

+ 

+    FFmpeg 6.1 "Heaviside", a new +    major release, is now available! Some of the highlights: + 

+ 
    +   
  • libaribcaption decoder
    • +   
  • Playdate video decoder and demuxer
    • +   
  • Extend VAAPI support for libva-win32 on Windows
    • +   
  • afireqsrc audio source filter
    • +   
  • arls filter
    • +   
  • ffmpeg CLI new option: -readrate_initial_burst
    • +   
  • zoneplate video source filter
    • +   
  • command support in the setpts and asetpts filters
    • +   
  • Vulkan decode hwaccel, supporting H264, HEVC and AV1
    • +   
  • color_vulkan filter
    • +   
  • bwdif_vulkan filter
    • +   
  • nlmeans_vulkan filter
    • +   
  • RivaTuner video decoder
    • +   
  • xfade_vulkan filter
    • +   
  • vMix video decoder
    • +   
  • Essential Video Coding parser, muxer and demuxer
    • +   
  • Essential Video Coding frame merge bsf
    • +   
  • bwdif_cuda filter
    • +   
  • Microsoft RLE video encoder
    • +   
  • Raw AC-4 muxer and demuxer
    • +   
  • Raw VVC bitstream parser, muxer and demuxer
    • +   
  • Bitstream filter for editing metadata in VVC streams
    • +   
  • Bitstream filter for converting VVC from MP4 to Annex B
    • +   
  • scale_vt filter for videotoolbox
    • +   
  • transpose_vt filter for videotoolbox
    • +   
  • support for the P_SKIP hinting to speed up libx264 encoding
    • +   
  • Support HEVC,VP9,AV1 codec in enhanced flv format
    • +   
  • apsnr and asisdr audio filters
    • +   
  • OSQ demuxer and decoder
    • +   
  • Support HEVC,VP9,AV1 codec fourcclist in enhanced rtmp protocol
    • +   
  • CRI USM demuxer
    • +   
  • ffmpeg CLI '-top' option deprecated in favor of the setfield filter
    • +   
  • VAAPI AV1 encoder
    • +   
  • ffprobe XML output schema changed to account for multiple variable-fields elements within the same parent element
    • +   
  • ffprobe -output_format option added as an alias of -of
    • + 
+ 

+    This release had been overdue for at least half a year, but due to constant activity in the repository, +    had to be delayed, and we were finally able to branch off the release recently, before some of the large +    changes scheduled for 7.0 were merged. + 

+ 

+    Internally, we have had a number of changes too. The FFT, MDCT, DCT and DST implementation used for codecs +    and filters has been fully replaced with the faster libavutil/tx (full article about it coming soon).
+    This also led to a reduction in the the size of the compiled binary, which can be noticeable in small builds.
+    There was a very large reduction in the total amount of allocations being done on each frame throughout video decoders, +    reducing overhead.
+    RISC-V optimizations for many parts of our DSP code have been merged, with mainly the large decoders being left.
+    There was an effort to improve the correctness of timestamps and frame durations of each packet, increasing the +    accurracy of variable frame rate video. + 

+ 

+    Next major release will be version 7.0, scheduled to be released in February. We will attempt to better stick +    to the new release schedule we announced at the start of this year. + 

+ 

+    We strongly recommend users, distributors, and system integrators to upgrade unless they use current git master. +
