N100 HW Transcoding QSV not working

[technut8]

I’ve set that in the UI. When playing a high bitrate 4k stream and transcoding to 1080p the CPU utilisation ranges from 15% to 60%. When I disable QSV it goes much higher. Initially I thought that the N100 could perform this using around 15% CPU, but I’ve read that what I’m seeing might be the expected result.

I wasn’t sure how to collect ffmeg logs? I did a bit of Googling and read that Linux doesn’t do this by default, unless there’s a way I can check logs in Jellyfin?

Thanks

Keep in mind that AUDIO is transcoded on the CPU. Always. Also keep in mind that 100% on a multi-core CPU means only a single core is being fully utilized. Or 4 cores are being utilized at 25%, etc. And since audio transcoding is single threaded, it's not unusual to see one core maxed out (100% as reported by top).

Logs are located in container path /config/log. You can also access them in the dashboard in Dashboard > Logs near the bottom of the left column.

Okay I’ll look into those logs. I read somewhere that audio transcoding can be disabled. Is this possible and are there any downsides? If audio transcoding uses CPU and it is only going to use a few mbps natively then perhaps I should disable it?

Based on all of this I’m pretty sure that it is doing the transcoding. I’ll still check the logs. Is there a place I can upload logs or do we just attach them here? I also noticed there is a transcode folder in the Playback settings, should this be mapped in the compose file as I didn’t see that mentioned in any guides. Thanks
