reassign 843144 ffmpeg
found 843144 7:3.1.5-1
thanks

Hi!

I am hitting this same issue but from what I could inspect, it's
something related with ffmpeg (and not vokoscreen)

For example, directly calling ffmpeg like this, it fails:

ffmpeg -f x11grab -draw_mouse 1 -framerate 25 -video_size 1920x1080 -i
:0+0,0  -pix_fmt yuv420p -c:v libx264 -preset veryfast -q:v 1 -s
1920x1080 video.mkv

The above example is basically what vokoscreen is using.
We can see a lot of frames being dropped.

When using -report it's possible to see a lot of messages like this:

=====
cur_dts is invalid (this is harmless if it occurs once at the start per stream)
[rawvideo @ 0x562345919700] PACKET SIZE: 8294400, STRIDE: 7680
Clipping frame in rate conversion by 0.000008
cur_dts is invalid (this is harmless if it occurs once at the start per stream)
[rawvideo @ 0x562345919700] PACKET SIZE: 8294400, STRIDE: 7680
(...)
=====

While this work:

ffmpeg -f x11grab -draw_mouse 1 -r 25 -s 1920x1080 -i :0.0+0 -vcodec
libx264 video.mkv

Tested with ffmpeg 7:3.1.5-1 and latest 7:3.2-2.
I am unsure if this could be a problem with some lib that ffmpeg uses
(and I don't know how to test this)

Thank you!

Best regards,
Nelson
