@ffmpeg-devel@ffmpeg.org tldr; Using exact screen size doesn't work but less one pixel does.
I'm new to ffmpeg but I see a recent message below and wonder there is an error now. The ffmpeg I built from source only yesterday. On a 1366x768 screen this below, sees the error suggested: ffmpeg -f x11grab -r 30 -s 1366x768 -i :0.0 -vcodec libx264 -preset ultrafast -crf 0 -y output.mkv [x11grab @ 0xa578ae0] Capture area 1366x768 at position 0.0 outside the screen size 1366x768 :0.0: Invalid argument This with one pixel size down, works fine: ffmpeg -f x11grab -r 30 -s 1365x767 -i :0.0 -vcodec libx264 -preset ultrafast -crf 0 -y output.mkv Regards davidpbrown ================== Re: [FFmpeg-devel] [PATCH] Fix segfault with x11grab when switching windows.

Good fix. The segfault is now avoided and the following message is seen: [x11grab @ 0x28c7200] Capture area 1920x1147 at position 0.53 outside the screen size 1366x768 :0.0+0,53: Invalid argument (return code 1) Thanks, Matt _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
