Weird playback issue

Ah.  Haswell has limited QSV functionality anyway.

But don't expect miracles with VAAPI.  Its performance is dependent on the raw graphics performance of your CPU.  Probably should have asked what hardware you had from the get go.  The client probably isn't freezing.  Just waiting for the server to transcodes (probably via the CPU alone) and just isn't doing that fast enough.

Are there ffmpeg logs?

If you are watching in a browser, it probably wants to transcode to H264.  What happens when you use the desktop Jellyfin Media Player?

So if I watch say, Made In Abyss, in Chrome, it will say the server sent a format that isn't compatible
If I watch in Edge, it works (which is in line with Edge apparently supporting HEVC)
If I watch in Jellyfin Media Player (windows client) it just hangs indefinitely (This is regardless of if I force transcoding HEVC or if I force direct playback in client settings)
