• How should I make ffmpeg "-ignore_unknown" work ?

  10 janvier 2024, par living being

  I'm batch-converting some videos and I want ffmpeg to just drop any unknown stream instead of failing and leaving the video untouched.

  


  My code :

  


  find ./ -type f -iname '*.mp4' -exec bash -c 'var="{}" && ffmpeg -i "{}" -map 0 -vcodec libx265 -preset fast -crf 31 -vf "scale=-2:min(1080\,ih)" -acodec libopus -ac 1 -b:a 24K -c:s copy -ignore_unknown "$var.mp4" -y && rm -v "$var" && mv -- "$var.mp4" "$var"' \;


  


  streams :

  


  Stream #0:0[0x1](eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 105 kb/s (default)

Stream #0:1[0x2](eng): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv, smpte170m/smpte170m/bt709, progressive), 320x240, 491 kb/s, 30.12 fps, 30.12 tbr, 2500 tbn (default)

  handler_name    : Apple Video Media Handler
  vendor_id       : [0][0][0][0]

Stream mapping:
Stream #0:0 -> #0:0 (aac (native) -> opus (libopus))
Stream #0:1 -> #0:1 (h264 (native) -> hevc (libx265))
Stream #0:2 -> #0:2 (copy)
Stream #0:3 -> #0:3 (copy)


  


  In the end I get this :

  


  [mp4 @ 0x55f412caa240] Could not find tag for codec none in stream #2, codec not currently supported in container
[out#0/mp4 @ 0x55f412c97ec0] Could not write header (incorrect codec parameters ?): Invalid argument
[vost#0:1/libx265 @ 0x55f412ec3d00] Error initializing output stream: 
[libopus @ 0x55f412ec3200] 1 frames left in the queue on closing

encoded 0 frames
Conversion failed!


  


  

  


  OS : Ubuntu 23.10

  


  I know I can do it by eliminating "-map 0", but I want to include all subtitle streams and other types of known streams if any. I need to use this for terabytes of videos, so I can't totally exclude data streams either, since there are some useful ones.

  


• ffmpeg fails to open a WAV file - "too short LIST tag" [closed]

  5 janvier 2024, par brad

  I have a WAV file exported in FL Studio 21.2.2 on Win10, which ffmpeg/ffprobe cannot open.

  


  When running :

  


  ffprobe -v error -show_format -print_format json -hide_banner -i "path/to/file.wav


  


  This exception is thrown :

  


  [wav @ 0x132704440] too short LIST tag
[in#0 @ 0x132704340] Error opening input: Invalid data found when processing input


  


  Here's a screenshot of the file metadata in macOS

  


  Since i'm not able to open the file with ffmpeg, i can't correct/remove the metadata. Any ideas what I can do ? File is available upon request. Thanks !

  


• FFMPEG PNG sequence into mkv cause "inflate returned error -3" every 600-800 frames [closed]

  30 novembre 2023, par sergey9295

  I am new to ffmpeg. I try to use it for creating videos from png sequences. I have uncompressed pngs. All of them rgb24 format.

  


  But during encoding process I get inflate errors. I compared PNG and video frame by frame. And video have approximately 1 dupe frame every 600-800 frames instead of the ones that should be on that places. I tried another codecs, tried to clear png's EXIF(it made things even worse), made sure that memory was enough. Doesn't matter.

  


  The worst part is that this errors are pretty random. I encode one sequence 3 times and get 3 different sets of error-causing frames.

  


  FFMPEG was downloaded from official site.

  IMO the problem is zlib from libpng. But I don't have skills to recompile it with libspng that doesn't require zlib. Maybe there is a ffmpeg version without this error ?
