• Errors converting EXRs to mp4 with ffmpeg

  3 février 2021, par GaryO

  I'm using ffmpeg 4.3.1 to convert some EXRs to mp4, with tone mapping for the extended range in the source and rec709 conversion for the mp4.

  


  I'm using this command :

  


  ffmpeg -pattern_type glob  -framerate 24 -i 'frames/*.exr' -vf zscale=transfer=linear,tonemap=hable,zscale=transfer=bt709,format=yuv420p -c:v libx264 -r 24 -preset slow -crf 18 -pix_fmt yuv420p foo-tonemap-01.mp4


  


  but it gives me this error :

  


  Input #0, image2, from 'frames/*.exr':
  Duration: 00:00:00.08, start: 0.000000, bitrate: N/A
    Stream #0:0: Video: exr, gbrapf32le, 1920x1080 [SAR 1:1 DAR 16:9], 24 tbr, 24 tbn, 24 tbc
Stream mapping:
  Stream #0:0 -> #0:0 (exr (native) -> h264 (libx264))
code 3074: no path between colorspaces
Error while filtering: Generic error in an external library


  


  What does that error "no path between colorspaces" mean ? Do I need to tell it what colorspace the EXRs are in (scene-linear RGB) or something ?

• ffprobe reports some wrong meta data but only when input is piped in

  17 juillet 2020, par spinkus

  I have a video file and I'm using ffprobe to extract meta data from it. If I save the file to disk and runffprobe everything works fine. However, if I pipe the input into ffprobe most meta data is correct, but some fields, such as width, height, display_aspect_ratio are not correct. ffprobe reports these errors when input is a stream (see full outputs below) :

  


  


  [mov,mp4,m4a,3gp,3g2,mj2 @ 0x563c3de3c000] stream 1, offset 0x2c : partial file
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x563c3de3c000] Could not find codec parameters for stream 0 (Video : mpeg4 (mp4v / 0x7634706D), none, 1567 kb/s) : unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options

  


  


  I tried various settings for analyzeduration and probesize with no change in outcome. I tried piping other even larger MP4 files into ffprobe and the height and width is reported correctly, and I don't get "stream 1, offset 0x2c : partial file" output warning. I think there is may be some issue with this particular file, but if that's the case why does it only cause issues when the file is streamed in ?

  


  Any ideas what the issue is and how to get ffprobe to work same with a pipe as for a file input ?

  I have spent my entire day to solve this issue but everything failed. Anybody has idea about what i am missing and doing wrong ?
  Thanks in advance.
