Description

Hello @all,

I observed a strange issue when using NVIDIA Quattro P5000 to decode MPEGTS, H265 or H264 input streams.

nvidia-smi pmon
# gpu        pid  type    sm   mem   enc   dec   command
# Idx          #   C/G     %     %     %     %   name
    0      31069     C     0     0     4     0   tvheadend

    0      31069     C     0     0     4     0   tvheadend
    0      31069     C     0     0     4     0   tvheadend
    0      31069     C     0     0     4     0   tvheadend
    0      31069     C     0     0     3     0   tvheadend

As you can see decoding is 0. I would expect some output for the GPU, when hwaccel is active.

I was not able to find something on the logs indicating any information on hwaccel.

So I presume a small bug in the hwaccel module.

If you need more information I'm willing to help.
