Ok so I have been trying a few different things, I mapped /dev/dri:/dev/dri to the container and started by using /dev/dri/renderD128.
I can now see the following which shows that Intel Transcoding is working:
<TranscodeSession key="/transcode/sessions/agwksbuljfbg5ty0okf02twh" throttled="1" complete="0" progress="1.1000000238418579" size="-22" speed="0" error="0" duration="9153520" remaining="49117" context="streaming" sourceVideoCodec="h264" sourceAudioCodec="ac3" videoDecision="transcode" audioDecision="transcode" protocol="dash" container="mp4" videoCodec="h264" audioCodec="aac" audioChannels="2" transcodeHwRequested="1" transcodeHwDecoding="vaapi" transcodeHwEncoding="vaapi" transcodeHwDecodingTitle="Intel (VA API)" transcodeHwFullPipeline="1" transcodeHwEncodingTitle="Intel (VA API)" timeStamp="1686046610.4160163" maxOffsetAvailable="98.014681348014676" minOffsetAvailable="0"/>
However /dev/dri/renderD129 or /dev/nvidia0 still will not show anything for the NVIDIA card:
<TranscodeSession key="/transcode/sessions/6smcuu5i1gm6zflijuk3iequ" throttled="1" complete="0" progress="1.7999999523162842" size="-22" speed="0" error="0" duration="10157664" context="streaming" sourceVideoCodec="hevc" sourceAudioCodec="eac3" videoDecision="transcode" audioDecision="transcode" subtitleDecision="transcode" protocol="dash" container="mp4" videoCodec="h264" audioCodec="aac" audioChannels="2" transcodeHwRequested="1" timeStamp="1686046992.4430592" maxOffsetAvailable="331.03937270603927" minOffsetAvailable="149.02401733398438"/>
I assume it will be @ChuckPa who will look into this - I have read through everything here: NVIDIA hardware acceleration inconsistently working with web streaming - #132 by ChuckPa
Not sure if its related as I just cant get anything working on nvidia at all that I can see, I have added 3 logs here with each test pointing to the device I had used at the time in Preferences.xml - hopefully this makes more sense to you!
