Errors converting EXRs to mp4 with ffmpeg
3 février 2021, par GaryOI'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 ?

Parsed_concat_1 @ 02ad98e0 Failed to configure output pad on Parsed_concat_1
3 décembre 2015, par user650922I am using NReco.VideoConverter(FFMPegConverter) to ConcatMedia. However, I am getting error as Parsed_concat_1 @ 02ad98e0 Failed to configure output pad on Parsed_concat_1.
Here is the code snippet of my code :
try
{
var ffMpeg = new FFMpegConverter();
var set = new ConcatSettings
{
ConcatAudioStream = false
};
set.SetVideoFrameSize(1080, 720);
set.MaxDuration = 500;
ffMpeg.ConcatMedia(videos, output + ".mp4", Format.mp4, set);
return output + ".mp4";
}
catch (Exception ex)
{
var text = new List<string>();
text.AddRange(videos);
text.Add(ex.Message);
throw new Exception(string.Join(", ", text), ex);
}
</string>VideoFrameSize of all the videos is(1080, 720) and FrameRate is 25.
Could some one please help me to resolve the issue.
