I'm using a static git build, version N-46353-g40b7e6071-static[1] on CentOS 7.3. This server is used as a remote login launch point (or "jump box"). What we'd like to do, for security/auditing purposes, is create videos of user sessions.
I'm using a command like this: # ./ffmpeg -an -f x11grab -framerate 10 -video_size 1280x1024 -i :13 /tmp/cap.mp4 If I stop ffmpeg before that display is closed, I get a nice video, exactly as expected. However, if ffmpeg is still running when the display (:13 in the above command) is closed, ffmpeg segfaults. This results in an unplayable video file (presumably, ffmpeg doesn't get a chance to clean up and properly close out the file). Would this be considered a bug? Not sure how hard it would be to recognize that the display is no longer valid, and cleanly exit... Is there any kind of workaround possible? Thanks!
