ARM transcoding

[Serj-47]

I have a Chinese tvbox that has been converted into a NAS, those on it have a full-fledged linux armbian installed and a hard drive is also connected on which files with my media collection are located.In Armbian linux, I use docker for some applications, for example, for 'transmission' and it works quite normally. My question is, can I use the Jellyfin docker and transcoding version to view media content over the network? To be more precise, I am interested in whether the performance of the box is enough for video transcoding? Hardware: Amlogic CPU- Amlogic s905x3,, GPU-G31MP2, 4 GB RAM

It will work to an extent, as the v4l2mem is available for this SoC. However, don't expect too much from it, as its performance is not adequate for Jellyfin.

Thanks for your reply. I installed the jellyfin server, the docker version on one of my s905x2 TV boxes. And it works!) When playing transcoded video on my phone in the jellyfin app, I can watch it without stuttering in 480 resolution. At the same time, I see 100% CPU usage on the TV box, and this is not surprising.
How do find out which type of transcoding is used on the server, software or hardware?

As I indicated in my message above, the load of all soc cores on the server when using software transcoding is about 100%. I tried to enable hardware decoding v4l2 in the jellyfish app on my phone, but now the content is no longer playing, giving an error.

The launch parameters of the docker container on the server look something like this:

Code:

docker run -d  --name jellyfin-linuxserver \
--net=host  \
--volume /srv/usb-disk/Storage2/jellyfin/config:/config \
-e TZ=W-SU \
-e PUID=1000  \
-e PGID=1000  \
--volume /srv/usb-disk/Storage2/jellyfin/cache:/cache  \
--mount type=bind,source=/home/serj/Storage-nfs,target=/media \
--restart=unless-stopped  \
--device=/dev/dri/:/dev/dri/  \
--device=/dev/video0:/dev/video0  \
linuxserver/jellyfin

Code:

ls /dev/dri                                              
by-path  card0  card1  renderD128
ls /dev/video*
