SOLVED: Proxmox LXC Hardware Transcoding

[C0nfigurator]

Also, what I just noticed, when looking at my installed packages I can see that jellyfin-ffmpeg7 is installed. But when I want to check if the encoding is working with the following command:

ffmpeg -init_hw_device qsv=hw -filter_hw_device hw -v verbose -i Input.mkv -filter:v "scale=1920:-2,flags=lanczos,unsharp=5:5:.03:5:5:0.0" -c:v hevc_qsv -preset veryslow -extbrc 1 -look_ahead_depth 99 -b_strategy 1 -bf 7 -mbbrc 1 -rdo 1 -low_power 0 -adaptive_i 1 -adaptive_b 1 -async_depth 7 -b:v 25M -color_range tv -color_primaries:v bt709 -color_trc:v bt709 -colorspace:v bt709 Output.mkv

I get an error message that ffmpeg is not installed. Do I need to install the ffmpeg package as well?
