Async depth will allow qsv filter cache few frames, and avoid force
switch and end filter task frame by frame. This change will improve
performance for some multi-task case, for example 1:N transcode(
decode + vpp + encode) with all QSV plugins.

There was an assumption in the existing code that indentation would not occur
more than once on the same row.
This was a bad assumption. There are examples of 608 streams which call
handle_pac multiple times on the same row with different indentation.
As the code was before
Both motion vector tables have the same number of elements, hence one
can inline said number and remove the field containing the number of

These two functions are always called after another; after all, what
ff_dolby_e_parse_init does is obviously part of parsing the frame header.
Also move the DolbyEHeaderInfo into DBEContext so that parsing the frame
header only needs one struct (both users used a DBEContext immediately
followed
Parsers are not forced to use a ParseContext and the other stuff from
parser.h which is just designed to help parsers recombining frames. But
this parser does not do this at all, i.e. the ParseContext is unused.

This patch allows ffmpeg to capture a specific window instead of the whole
