Some Hikvison RTSP cameras send wrong sprop-parameter-sets in SDP - it's
missing PPS.
Example of correct sprop-parameter-sets:
sprop-parameter-sets=Z0IAH5W4PASaEAAAcIAAFfkAQA==,aM48gA==
Example of wrong sprop-parameter-sets:
sprop-parameter-sets=Z0IAH5WoPASaEAAAcIAAFfkIQA==,
My patch adds a workaround that ignores invalid sprop-parameter-sets.
