Flush & Latency Issue with Fragmented MP4 Creation in FFMPEG

Question

I\'m creating a fragmented mp4 for html5 streaming, using the following command:

-i rtsp://172.20.28.52:554/h264 -vcodec copy -an -f mp4 -reset_timestamps 1          


        

Answer 1

Usually the buffering for stdout is disabled in case of console output. If you run ffmpeg from code, the buffering is enabled, so you will get your data only when the buffer is full or the command ends.

You have to eliminate the stdout buffering of your os. On windows its impossible imo, but on ubuntu for ex. There is http://manpages.ubuntu.com/manpages/maverick/man1/stdbuf.1.html
