Web Presenter + Linux widescreen

Hi

My Linux installation (Debian 8 i386) with OBS Studio + Webpresenter works fine except V4l2 only sees a 640x480 image. Has anyone dealt with this problem?

Thanks

Multiple resolutions and codecs are supported. 640x480 is the highest for raw video, 720p is the highest for the MJPEG codec. See for example: https://askubuntu.com/questions/214977/ ... solutions/

Yes, thanks for the info. I found out that the settings for a v4l2 video device need to use either YU12 or YV12 as the format before you can access the 1280 x 720 frame size.
