Problem with remote playback

[bitmap]

Can you provide an ffmpeg log for the item transcoding? Looks like it's not using hardware acceleration (see lines 337+). Maybe a screenshot of your hardware acceleration options in Jellyfin web? Would be helpful to know how you're running Jellyfin (e.g., bare metal, OS, virtualization).

Here's the line in question IMO:

Code:

The ffmpeg command is not calling any hardware devices. Your iGPU on the i5-12400 should be set as the transcoding device to enable HWA.
