Jellyfin ffmpeg permission denied
11 septembre 2022, par SteveI am running Jellyfin on a Raspberry Pi 4 in a docker container (https://hub.docker.com/r/linuxserver/jellyfin) and am trying to set up hardware accelerated video transcoding. I'm fairly certain I have set up the video devices & permissions correctly, but I am getting the following exception in the logs when trying to play a video through the web interface :

The real head-scratcher is that if I log in to the docker container with
docker exec -it /bin/bashand paste the ffmpeg command from the logs and run it, it works fine.

I'm running as the
jellyfinuser, which is in thevideogroup, and has read/write access to the media directory.

Any thoughts ?


My docker-compose file is attached below, if any other system information is needed let me know.

Issues with using FFmpeg to generate MPEG-DASH files
26 septembre 2022, par Tina JI am using the following
ffmpegcommand to generate MPEG DASH files and manifest. I usesingle_file 1to have a single file for each representation ; so no chunking. But IDK why when I want to play the manifest using ExoPlayer, the video doesn't play from the beginning (rather it starts from around 50s).

ffmpeg -re -i .\video-h264.mkv -map 0 -map 0 -c:a aac -c:v libx264 -b:v:0 800k -b:v:1 300k -s:v:1 320x170 -profile:v:1 baseline -profile:v:0 main -bf 1 -keyint_min 120 -g 120 -sc_threshold 0 -b_strategy 0 -ar:a:1 22050 -use_timeline 1 -single_file 1 -use_template 1 -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" -f dash out.mpd


What is wrong with this ? Is the manifest correct ? Here is the generated mpd :
