    Originally, I was trying to add a subtitle to in.mkv, but I keep encountering this error. When I add the subtitle to another MKV file, it works fine, so I believe the problem lies with in.mkv.

    


    Troubleshooting

    


    Output only video stream produce the same error :

    


    ffmpeg -i in.mkv -map 0:v:0 -c copy out.mkv


    


    Output only audio stream works fine :

    


    ffmpeg -i in.mkv -map 0:a:0 -c copy out.mkv


    


    Output as mp4 got no error, but the output file is unplayable :

    


    ffmpeg -i in.mkv -c copy -strict -2 out.mp4


    


    Re-encoding works fine :

    


    ffmpeg -i in.mkv -c:v libx265 -c:a copy out.mkv


    


    How can I fix the video stream in in.mkv so that I can add a subtitle stream and remux the file without re-encoding the video ? Any insights or suggestions on handling this error would be greatly appreciated.

  • Reduce ffmpeg CPU usage with h265 [closed]

    23 septembre 2024, par Neskelogth

    I have a video file to convert using ffmpeg on Ubuntu 22.04. The input uses the codec h264 and I want to convert it to h265 (mainly for storage capacity reasons). The output of ffmpeg -version is

    I saw online that one of the options of ffmpeg is -threads, but apparently it does not work, since using ffmpeg -i input.mp4 -c:v libx265 -c:a copy output.mp4 and ffmpeg -i input.mp4 -c:v libx265 -c:a copy -threads 2 output.mp4 seem to be exactly the same in terms of CPU usage as shown by htop. Is there something wrong in my usage of -threads ?
