Hello,
I am using an GTX690 unlocked card (equivalent to double K10) to
transcode live mpeg2 to h264 as here:
/usr/local/bin/ffmpeg -i udp://239.255.254.2:1234?overrun_nonfatal=1 -y
-c:a copy -c:v nvenc -b:v 4M -profile:v high -preset default -bufsize 8M
-s hd720 -segment_list_flags live -segment_time 4 -segment_format
mpeg_ts -gpu 1 -metadata title=RDI m3u/RDI/stream.m3u8
All is is fine (thanks to Moritz Barsnick from this list for help) till
I transcode only one channel per gpu. If I however send a second channel
to the same gpu (-gpu 1 above), the ffmpeg will refuse to start.
So, my question is if there is a way to have >1 instance of ffmpeg using
the same GPU at the same time? The GPU's have enough power for several
channels in parallel.
In /dev I have: /dev/nvidia0 /dev/nvidia1 /dev/nvidiactl
/dev/nvidia-uvm
Any suggestion appreciated,
Thanks, George.
