Issue Transcoding in Jellyfin LXC on Proxmox: Driver Does Not Support VBR RC Mode - Jumper72 - 2023-12-20
Hello Jellyfin Community,
I am experiencing an issue with FFmpeg transcoding in Jellyfin running on a Proxmox LXC. The error message is as follows:
[h264_vaapi @ 0x55659fbec280] Driver does not support VBR RC mode (supported modes: CQP).
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
[h264_qsv @ 0x55f73a2e9c40] Selected ratecontrol mode is unsupported
[h264_qsv @ 0x55f73a2e9c40] some encoding parameters are not supported by the QSV runtime. Please double check the input parameters.

Conversion failed!

The issue seems to arise during playback of certain media types. I would appreciate any insights or suggestions on how to resolve this error, particularly regarding the VBR RC mode and potential parameter adjustments in FFmpeg transcoding settings. Also with getting QSV working as i heard its more efficient?
Thank you!

I tried making those changes, rebooted but im still getting these errors

But do they prevent the transcode from happening? Is this a privileged or unprivileged container?

I solved this by disabling low power decoding. It is working with Intel QSV Now
