Re #1213 (Video devices):
 - Video device now opens in "best effort" mode, i.e. it may open with different size and fps than requested. The actual size and fps will be reflected in the "param" upon return. The vidport must check this against any differences, and create converter accordingly.
 - Removed const for param argument in vid_create_stream() API
 - Currently converter in vidport will not work if vidport is opened in bidir. Converter for renderer is untested
