Ultragrid crashes windows computer #319

Closed maybites closed 9 months ago

maybites commented 1 year ago

Hi

I encounter a reproducable crash (und subsequent freeze) on my machine with the latest Ultragrid Release.

It happens when I try to send a 4k Spout stream with the following CLI command:

--param log-nocolor -P11032 -t spout -c libavcodec:codec=H.264:bitrate=80M 10.128.96.104

It doesn't happen with the MJPEG codec..

I can provide the memory dump file or access to my machine if required.

Hi, for now I'd like to ask you if you can try some further attempts. I've just tried with current continuous and 1.8.3 build with the stream produced by UltraGrid:

uv.exe -t testcard:mode=uhd -d spout # generate the stream; works in continuous; in 1.8.3 it needs more verbose syntax:
# uv.exe -t testcard:size=3840x2160 -d gl:spout:hide-window
uv.exe -t spout:name=UltraGrid -c libavcodec:codec=H.264:bitrate=80M <dest>

which worked correctly for me. Would it be possible to try this out?

Also the terminal output of the crashed instance might help. Not sure about the memory dump - I recall that in the past I was not able to get much useful info from it, if we do not succeed, I can try it once more. The remote access might be more useful, but I'd ask you for the above first.
