how to make a ffmpeg wrapper ?
Posted: Thu Dec 08, 2011 12:34 pmHi!
I use serviio 0.6.0.1 on FreeBSD/amd64 from ports collection. And I have some problems when playing videos on xbox360 slim.
Playing is very laggy.
My hardware is intel quad-core Q6600 running at 2,4GHz with 8GB of RAM.
Careful study showed that FFmpeg works in one thread. I wrote a ffmpeg wrapper called ffmpeg-mt, which clearly indicated the parameters:
/usr/local/bin/ffmpeg-mt
And edited /usr/local/sbin/serviiod
cat /usr/local/sbin/serviiod
In this case the wrapper correctly work from the command line, but does not runs from serviio.
grep -A 3 ffmpeg-mt /var/log/serviio/serviio.log
How do I correctly specify serviio to run ffmpeg in 4 threads?
