• FFmpeg set playing buffer to 0

  8 janvier 2015, par Mihai Ghete

  I’m using FFmpeg to play RTMP streams inside an iOS application. I use av_read_frame to get the audio and video frames. I need the latency to be as small as possible at all times, but if there’s a bottleneck or the download speed decreases, av_read_frame is blocked. Of course, this is how it should work. The problem is that FFmpeg waits too much. As much as it needs to fill its buffers. I need to set those buffers to a value close to 0. Right now, I’m dropping buffered packets "manually" to get the latency at the initial value. The result is the desired one, but I’d wish FFmpeg won’t buffer in the first place...

  Can anyone help me with this ? Thanks in advance.

• FFMPEG "-to" option won't stop encoding at the implied time

  11 janvier 2018, par Saber Karimi

  I’m using ffmpeg to cut and covert a part of a long video but when using the "-to" option ffmpeg keeps encoding till the end of the video and wont stop.

  Here’s my command :

  ffmpeg -ss 00:22:59 -i input.mkv -to 00:23:15.5 -c:v libx264 -c:a aac output.mp4

  if i change to "-t" and enter my desired duration, problem goes away. but since i have a very long video and many tasks i need to use "-to" which is easier for me.

  Thanks in advance.
