  • Ffmpeg x265 error : "Color Primaries must be", "ransfer Characteristics must be", "Matrix Coefficients must be" [closed]

    16 septembre 2022, par Mister Sir

    I'm trying to do the following conversion :

    


    ffmpeg -i video.mp4 -map 0 -c copy -c:v libx265 -crf 30 -vf "scale=-1:\'min(720,ih)\'" -c:a libopus -b:a 44k -map_metadata 0 -loglevel error -hide_banner video.mkv


    


    This works fine except for a specific video. I'm getting the following output :

    Can't find a single result when I google the first error text, ffmpeg "Color Primaries must be unknown"

    


    This is the verbose output :

    I'm not an expert at video encoding, so I don't really know what this all means. Probably something with the source file. How to get around this ? Thanks in advance ! If I need to upload the video, let me know how I can do that.
