Hi all, I have a problem which I think is something to do with avconv, one
or more codecs, and possibly related to the way I'm using them.
I capture my screen (with audio) using this command:
avconv -f alsa -i pulse -f x11grab -r 30 -s 1280x720 -i :0.0+100,125
-acodec ac3 -vcodec libx264 -pre:0 lossless_ultrafast -threads 0
video-$(date +%F-%H-%M-%S).mkv
and during recording, it spits out some warnings about non monotonous ...
and tells me that this may result in incorrect timestamps in the output
file. Possibly noteworthy is that the values is prints seem to suggest that
somehow this count went "backwards" relative to it's earlier number
(e.g.: previous: 9138, current: 9123; changing to 9139)
Which version are you using? recently we switched to use the monotonic
clock to avoid such problems.
