Hi users, Have a problem that I've long needed a solution for. I record my screen using this command using a bat script to automate the process: ex. c:\ffmpeg\ffmpeg\bin\ffmpeg.exe -rtbufsize 1000M -f gdigrab -framerate 15 -i desktop -f dshow -i audio=%Device% -flags +global_header -vcodec libx2

Hi All! I'm revisiting this issue because I've finally had time to narrow down the exact release where this issue first arose from so that perhaps someone who understands the code could maybe figure out what may have happened. From this page: https://ffmpeg.zeranoe.com/builds/win32/static/ Scrol
