Well, my issue is simple to explain, but I tried everything to solve it without success.
I like recording gameplays, just for fun. The game I currently make recordings for is not resource heavy (it’s Doom 2 through GZDoom). I’m using Lubuntu 22.04.
So, here is the command I’ve just used:
ffmpeg -f x11grab -draw_mouse 0 -framerate 30 -probesize 42M -video_size 1920x1080 -i :0 -f pulse -i default -c:v libvpx-vp9 -r 30 -g 90 -quality realtime -frame-parallel 1 -qmin 4 -qmax 48 -b:v 4500k -c:a libvorbis prueba.mkv
The issue is, if I record without including the audio, then the video plays smoothly after being recorded. But if I record including the audio, no matter what parameters, codecs, bitrate or anything I use, then the video is barely watchable, with lots of choppiness, and even with delay between audio and video, apparently.
SimpleScreenRecorder works fine, but sometimes there are few frames dropped and I don’t like it much. OBS is very heavy for my hardware (Mac Mini 2016, Intel Core i5 1.4 GHz 4260U, Intel HD Graphics 4000, 4 GB RAM).
I also tried VAAPI, with same results as above.
And the thing is that I remember recording some years ago, with no issues at all.
I don’t know what to do. Any tip or solution?
Weird! Yeah I don’t understand either, but this info may help in further debugging.
Have you tried playing with the container format? I know .mkv is generally preferred but maybe try .mp4 or something else. My thinking here is that both audio and video work, but somehow muxing them is failing. Using a different container could maybe help since the muxing is different (???).
Other thing to try is of course making sure ffmpeg is up to date but it sounds like you’re on top of that.
Good luck!
