Otherwise, during error conditions, the caller will be left with
dangling pointers to a destructed packet => boom.

The code that copies any extradata from the MXFDescriptor to the codec does
not set the size, which it should otherwise the copied data is useless.

Allowing to automatically select the concat demuxer raises
security concerns, as it allows a possibly hostile file to
access any file on the system. Guessing the format based on
the file name extension does not allow to enable the safe
mode designed to avoid it.
When parsing the Xing/Info tag, don't set the bit rate if it's an Info tag.
When parsing the stream, don't override the bit rate if it's already set,
otherwise calculate the mean bit rate from parsed frames. This way, the bit
rate will be set correctly both for CBR and VBR streams.

The warnings are false positives, older gcc versions (such as 4.5)
think the variables can be used uninitialized while they in
practice can't, while newer (4.6) gets it right.

flvdec: Don't read the VP6 header byte when setting codec type based on metadata
Conflicts:
libavformat/flvdec.c
Merged-by: Michael Niedermayer <michaelni@gmx.at>
The callers of this function can't report errors sanely. If this
one malloc fails, don't write the extradata byte, make sure we
try to malloc it the next time we're called instead, and make sure
we still consume the input data byte.

This header byte is only present when actually reading a VP6 frame,
not when reading the codec type field in the metadata. This
potential bug has been present since 5b54a90c.

If the first "special" character in a filename is a comma,
it can introduce protocol options, but only if there is a
colon at the end. Otherwise, it is just a filename with a
comma.
Fix trac ticket #2303.
