  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.
