[closed] Transcoding on i3-N305 / iGPU

[bitstream]

>  1. You installed vanilla ffmpeg instead of jellyfin-ffmpeg (zero-copy transcoding will be disabled)
This point I can rule out.

> 2. Some hardware codecs are not enabled in the dashboard
Except for VP8 all offered codes for decoding are activated
Hardware encoding incl. both intel low power encoders are also activated.

> 3. Audio transcoding is happening, which can only run on the CPU
Yes, audio transcoding is happening. See example below. 

Is my understanding incorrect, that audio de- and encoding compared to video de- and encoding would only take a fraction of cpu time? Meaning, it shouldn't make a big difference and wouldn't explain the results of my tests above?

I.e.
