is there a way for discovering all the available encodings of a certain webcam (e.g x-raw-rgb -xraw-yuv)?
Morevoer, I would like to discover also the available resolutions.
Thanks!
Yes, set the v4l2src element to ready and check the caps on the src pad. The element will narrow the list of caps down to the ones actually supported when it has opened and queried an actual device. That happens in READY state.
