SOLVED: AV1 + subtitles doesn't work with hardware acceleration enabled

Hi TheDreadPirate,

Thanks for your explanation!  And sorry for the late reply as somehow I didn't receive any notifications.

If I understand it correctly, without subtitles, if the client supports AV1 the server doesn't do any transcoding but just serve the video directly, right?

I'm using an AMD Ryzen 3 5900HX with bundled GPU which should be a Vega 8.  Can you help me verify whether hardware acceleration is available for AV1 for this chipset?  Thanks!
