Broken video on OSX 10.10.5

[benjo2000]

When i try to record my screen with "ffscreencast --sargs="-capture_cursor 1 -capture_mouse_clicks 1"" on OSX Yosemite the resulting video is broken, it looks like the horizontal lines are shifted (see attached screenshot)

Did you install the latest ffmpeg version from brew?
Could you please add ffmpeg version as well as your exact ffscreencast command with --dry and output attached

[benjo2000]

ffmpeg is 3.2.4, which should be the latest version.

command and output of ffscreencast:

ffscreencast --sargs="-capture_cursor 1 -capture_mouse_clicks 1" --dry
/usr/local/bin/ffmpeg -hide_banner -loglevel info -thread_queue_size 512 -f avfoundation -capture_cursor 1 -capture_mouse_clicks 1 -i "1" -c:v libx264 -crf 0 -preset ultrafast -threads 0 "/Users/bw/Desktop/Screencast 2017-03-22 at 19.32.44.mkv"

Hmm that's indeed very strange. Have you tried to start ffscreencast without any arguments to see if it has the same problem. Also do you have any other video player with which you could check the output video.

And just out of the blue, do you have any special software running that might interfere? Any extra effects added to OSX or something similar?

[benjo2000]

The problem stayed, even when started with no arguments.
It seems not to be player-related, tried it with vlc, iina and mplayer and i'm not aware of any effects-adding software on my macbook, but i will try to run it in safe-mode this evening

[benjo2000]

Unfortunately, the problem occured in safe mode, too.

Do you have any other screen-recording software that you could try and see if it also results in broken output videos?

Did a short test with Quicktime's build-in screenrecording feature. That works.
