3f086a2f66 avcodec/mpeg4videodec: Fix nonsense warning 
Since db77230894 parsing of
mpeg4-extradata lead to a "Failed to parse extradata" warning, because
ff_mpeg4_decode_picture_header returns AVERROR_INVALIDDATA in case that
no VOP was found. This patch adds a parameter to signify whether a
header (where the absence of a VOP does not raise an error) or not is
parsed. The first mode is of course used for parsing headers.

in the middle of the parsing. Sligtly slower, but this is needed to

cases.

24e0e149ad avformat/utils: be more strict about stream specifiers 
This reworks the code to be more strict about accepting stream specifiers. From
now on we strictly enforce the syntax in the documentation up until the
decisive part of the stream specifier. Therefore matching stream specifiers
always need to be correct, non matching specifiers only need to be correct
until the decisive part.

Also recursion is changed to a simple loop.
