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.
Attached it a patch to correct this.

Merged-by: Michael Niedermayer <michaelni@gmx.at>

This is consistent with the other ff* tools, and also avoids spurious
success reports when ret%256 = 0.

Without this fix, ffprobe would exit with a failure exit code if a stream
specifier is given that selects the last stream.

The new name is less confusing, since the variables represent times
rather than timestamps.

TODO: add some meaningful examples.

Based on the notes in libavcodec/aac_adtstoasc_bsf.c.

Consistent with the FLV muxer.

Possibly enhance readibility.

There is no much point in optimizing example code, and the -O2 flag is
annoying when debugging.

Simpler and less confusing.

the documentation is generated. Fix that.

Fixes ticket #2707.

This is part of normal operation with some formats. A warning should
indicate that something is wrong, and the documentation for AV_LOG_WARNING
says: "Something somehow does not look correct."

Since this message is most likely useful for debugging only, raise the
log level accordingly.
