This is the solution we've been using in XBMC for over 2 years for dvd still frames.
The problem is that the demuxer asks for probing of the codec in the mpeg stream.
This causes lavf to read the whole menu structure into internal buffers.
After which, it won't read from input stream anymore and no events triggers.

Also adjust some comment wording / spelling and reorder header #includes.

This field is used to store the number of bytes that should be written
as padding to a metadata header of a file.  For example:
 - The FLAC format's METADATA_BLOCK_PADDING [1]
 - The ID3v2 tag format's padding           [2]

Always use the actually read size as the offset instead of making
possibly invalid assumptions.

It's shorter and more consistent with the rest of the code.

AVStream.codec is always non-NULL

This only updates the case where there is no B frame reordering delay.

This allows collecting statistics on probing scores and the amount of data
probing needed for various files and formats.
For example it can be used to find out which formats tend to need more
data for probing or which files are probed with less certain/lower scores
