  Re-distribute hierarchical vector match pattern

  This commit modifies the hierarchical vector match patter. It
  avoids repeated SAD computation at same points. The function
  vp9_vector_sad_sse2 is called 12 times per 64x64 block, instead
  of 15 times as before. The effective coverage remains the same.

• avformat/webmdashenc : Be more strict when parsing stream indices

  avformat/webmdashenc : Be more strict when parsing stream indices
  The syntax of the adaptation_sets string by which the user determines
  
  the mapping of AVStreams to adaptation sets is
  
  "id=x,streams=a,b,c id=y,streams=d,e" (means : the streams with the
  
  indices a, b and c belong to the adaptation set with id x). Yet there
  
  was no check for whether these indices were actual numbers and if there
  
  is a number whether it really extends to the next ',', ' ' or to the
  
  end of the string or not. This commit adds a check for this.

• Fuji .mov file converted by ffmpeg doesn't play in Windows Media Player [closed]

  30 août 2023, par glipster

  My Fuji X-T3 generates an FHD movie as a .mov with HEVC video and PPM audio. The new Media Player on Windows won't play this (without buying a codec) so I convert it to .mp4 using ffmpeg CLI (ffmpeg -i in.mov out.mp4). The resulting .mp4 file uses AVC video and AAC LC audio. This plays fine in VLC, but will not play in Windows Media Player nor Media Player. I've experimented with various options, but nothing seems to work.
For the original source .mov file, MediaInfo identifies 3 streams :
1stVid : English, 201Mb/s, 1920*1080 (16:9), at 29.970 FPS, HEVC (Main10@L5.2@High)
1stAud : english, 2304 kb/s, 48.0 hKz, 24 bits, 2 channels,PCM (Little/Signed)
1 : QuickTime TC

  


  The Output .mp4 file shows :
1stVid : English 3312kb/s, 1920*1080 (16:9) at 29.970 FPS, AVC (High 10@L4)(CABAC/4 RefFrames)
1stAud : English 132 kb/s, 48.0 kHz, 2 channels, AC LC
1 : QuickTime TC

  


  Using ffmpeg CLI, I tried changing the bitrates for the video and audio, I tried removing the timecode stream, tried a different AAC codec, tried moving the metadata to the front (-movflags faststart), also tried -strict experimental, tried first converting to .mkv (which does work) and then converting to .mp4 (with and without copy). I had hoped one of these might work ; but nothing has worked thus far.

  


  Has anyone else solved this problem ? Any help would be greatly appreciated.
