[FFmpeg-user] fifo_size usage hangs ffmpeg

[Ajay Parashar]

> ffmpeg version 2.3.3

Please test current FFmpeg git head.

I downloded latest version 2.4.1, compiled and executed also but no luck.
Still facing same issue, ffmpeg hangs with usage of fifo_size.
Please find latest logs as below:


ffmpeg -i 'udp://226.0.0.1:1234?fifo_size=875000&overrun_nonfatal=1' -map 0:v:1 -map 0:a:0 -acodec copy -f mp4 2609_5v.ts
