Hi all,
Seeing odd behavior with screen capture recorder.
This always works on win 7. No problems. Even when resolution is set to
1920 x 1080
c:\ffmpeg\ffmpeg\bin\ffmpeg.exe -f dshow -i
video="screen-capture-recorder":audio="Microphone Array (Realtek High
Definition Audio)" -vcodec libx264 -pix_fmt yuv420p -preset ultrafast
-acodec pcm_s16le -ac 1 -ar 22050 C:\CMT\output.mkv
But it isn't working on this win 10 computer with the resolution set to
1920 x 1080. What happens is that it actually crops the image down to
1536x864
Output Below
c:\ffmpeg\ffmpeg\bin\ffmpeg.exe -f dshow -i
video="screen-capture-recorder":audio="Microphone Array (Realtek High
Definition Audio)" -vcodec libx264 -pix_fmt yuv420p -preset ultrafast
-acodec pcm_s16le -ac 1 -ar 22050 C:\CMT\output.mkv

Again, the video is still cropped even though the output says it's 1920 x
1080
Any ideas?
Thanks!
