• MP4 to HLS conversion error after resizing video using FFmpeg

  26 juillet 2023, par ITeptIcklyTa

  When trying to create HLS stream from original video, FFmpeg creates HLS stream without errors.

  


  ~ $ ffmpeg -i test.mp4 -f hls -hls_time 3 -hls_segment_filename seg%02d.ts stream.m3u8


  


  But when I resize video using this command, I get a timestamps warning :

  


  ~ $ ffmpeg -i test.mp4 -vf scale=426:240 test_240p.mp4
[mp4 @ 0xb400007429e52d00] Timestamps are unset in a packet for stream 0. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly
[mp4 @ 0xb400007429e52d00] Encoder did not produce proper pts, making some up.


  


  And when creating HLS stream from resized video, I'm getting an error :

  I tried to build FFmpeg from GitHub and install FFmpeg from repositories, and I'm still getting this error.
