I am working on video decoding using FFmpeg. When I try to decode a video which is encoded with h265 at a certain fps (ex: fps=25), the result is a decoded video but at a different fps. How can I decode a video at exactly fps=25, even if I have a high miss rate or dropped frames? I use this command to decode: ffmpeg -benchmark -i -f null /dev/null

I am running the above command on Odroid-XU3 board that contains 8 cores. The OS is Ubuntu 14.04 LTS.

Please, any help is welcome. Thank you in advance.

  • Are you talking of decode speed strictly or frames sent to the null muxer? – Gyan May 31 '18 at 13:22
  • I am talking about decoding speed, i.e. I want to decode a video of 10s in 10s, even with old hardware, despite, of course, the bad quality (dropped frames, miss rate). – Mohammed_BEY May 31 '18 at 16:54

You can add ‘-re’ to the ffmpeg command lint to process in real time. Ffmpeg will not drop frames though. So if it can’t decode that fast, you will still fall behind.
