None of these are likely unless the user is writing a file with two billion
streams or a duration of around two months.

There's a a potential DoS problem in this function. Say an MXF file is
created with a PixelLayout with a long run of non-zeroes. Such a file could be
sent quickly (packed) over the net and would unpack quite fast. mxfdec would
then read it byte-by-byte, which would take considerable time.

Coverity thinks ofs can end up 15, thus writing past the end of layout[]. This
is incorrect since it's always incremented by 2. Checking ofs <= 14 makes
Coverity happy and doesn't hurt.

This check is somewhat more lenient as would be ideal because we dont
know if the input is signed or unsigned

Allow to factorize code in video_decode_example(), simplify.

In avcodec_open2(), apply consistent casing and avoid "or" conjunction at
the beginning of a sentence, in the messages issued in case of
experimental codec usage.

Fixes mpegts-in-mov, ticket #987 / issue 2223.

Allow to specify a filename where to put the filtergraph description.

This is useful to override limitations or glitches of particular shell
environments, and allows a level of indirection for specifying
filtergraphs.

Avoid hanging file.
