While i agree, should we always let av_find_stream_info search the whole
file to sure we find all stream??? That doesn't make sence either. 
For live playback search up to probesize is just silly, it causes
channel changes to take ages.

This patch doesn't change that new streams can be added later, it only
changes so that av_find_stream_info stops on the first one.
