Detailed Description

video sink using SDL

input signature is one, two or three streams of uchar. One stream: stream is grey (Y) two streems: first is grey (Y), second is alternating U and V Three streams: first is grey (Y), second is U, third is V Input samples must be in the range [0,255].

just like gr_block::general_work, only this arranges to call consume_each for you

The user must override work to define the signal processing code

Implements gr_sync_block.
