Hello EveryOne,
I’m trying to make my docker cointainer working with hardware decoding/transcoding.
I have two card : 1 Intel and 1 nvidia.
EDIT 1 : intel i7
EDIT 2 : nvidia GT540m
Intel configuration :
Docker run :
docker run --name=plex --env="TZ=Europe/Paris" --env="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" --env="TERM=xterm" --env="LANG=C.UTF-8" --env="LC_ALL=C.UTF-8" --env="CHANGE_CONFIG_DIR_OWNERSHIP=true" --env="HOME=/config" --volume="/home/docker/plex/config/:/config" --volume="/home/docker/plex/transcode/:/transcode" --volume="/media/data/:/media/data" --volume="/config" --volume="/transcode" --device=/dev/dri/card1:/dev/dri/card0 --device=/dev/dri/renderD129:/dev/dri/renderD128 -p 1900:1900/udp -p 32410:32410/udp -p 32469:32469 -p 32413:32413/udp -p 32412:32412/udp -p 32414:32414/udp -p 3005:3005 -p 32400:32400 -p 8324:8324 --restart=always --detach=true plexinc/pms-docker:plexpass

Results :
The hardware transcoding is used but the quality is extremely bad …
picture will be added.

Results :
The hardware decoding is not working…
There is a way to get nvidia decoding working or better quality with intel QSV ?
Thnaks.
