Hardware acceleration not working on Debian 12 through Docker

[TheDreadPirate]

Because of the older architecture, it is falling back to the i965 driver instead of the modern iHD driver. But it does work from that perspective, as you can see from the output at the end with the codec support.

Also because of the older architecture, OpenCL support is not available. But that is only needed for HDR to SDR tone mapping. Your CPU doesn't have HEVC codec support anyway for that to work.

From what you've shared, as long as you checked the correct boxes in Dashboard > Playback > Transcoding, plain SDR to SDR transcoding should work.

Check VC1, MPEG2, H264 for decoding.
