Re: [libvidcap-devel] [win32] listing device modes

Thanks for your help.

For example, libvidcap does not know how to> convert motion jpeg into either rgb32, yuy2, or i420.I understood. but I my case there are some missing resolutions (over 640*480).
An other question : is there a way to get the native camera output mode (without conversion ?).
By exemple : on a camera which is capable to give me an mjpeg image format, is it possible to retrieve it ?
