Hello everyone,
Please disregard previous mail; I managed to start two channels on the
same GPU, however it is unreliable - first channel will start every
time, while second may fail or work. Investing. Just for information,
card is:
4:00.0 3D controller: NVIDIA Corporation GK104 [GeForce GTX 690] (rev
a1)
04:00.1 Audio device: NVIDIA Corporation GK104 HDMI Audio Controller
(rev a1)
05:00.0 VGA compatible controller: NVIDIA Corporation GK104GL [Tesla
K10] (rev a1)
05:00.1 Audio device: NVIDIA Corporation GK104 HDMI Audio Controller
(rev a1)
Sorry for the noise,
George.

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.
