multimedia/obs-studio: ddb> kernel panic on attaching v4l2 capture device to scene #143

Closed n0xa closed 1 year ago

n0xa commented 3 years ago

Reproduceable on my ThinkPad X1 Carbon Gen 8 running OpenBSD-CURRENT. Webcam device: uvideo0 at uhub0 port 8 configuration 1 interface 0 "Azurewave Integrated Camera" rev 2.01/60.04 addr 2

obs otherwise runs well, and I have successfully streamed to YouTube with it.

Steps to reproduce kernel panic in my environment: Add a source of "Video Capture Device (v4l2)" On the dialog, "Create new" is selected by default. Click "Ok" Camera light turns on. Screen locks up for a few seconds, then I get the text-mode display with a crash. Last few lines here. Photo of full screen output attached. Dmesg also attached.

kernel: page fault trap, code=0 Stopped at uvideo_vs_decode_stream_header+0x2c: movzbl 0(%rsi),%esi ddb>

I'd recommend to send this to bugs@openbsd.org, this is not a port's bug per se.
