"Could not set video options" when framerate > 30 #143

Open jfhr opened 3 years ago

jfhr commented 3 years ago

The following command:

ffmpeg -framerate 31  -f dshow -i video="screen-capture-recorder":audio="virtual-audio-capturer" ue.mkv

Produced this message:

[dshow @ 0000023d46b65240] Could not set video options
video=screen-capture-recorder:audio=virtual-audio-capturer: I/O error

Full output with -loglevel trace is attached but doesn't seem to provide any useful info. output-with-trace.txt

The same command works fine with -framerate 30, but anything above that doesn't work. The screen itself is running at 144 fps.

Screen capture recorder has a default maybe it can't go past that. I should probably allow it... Funding or PR welxome :)

Looks like the default can be changed by setting the registry dword default_max_fps in HKEY_CURRENT_USER\SOFTWARE\screen-capture-recorder. 30 is just the default-default.
