This is a per-file input option that adjusts an input's timestamps
with reference to another input, so that emitted packet timestamps
account for the difference between the start times of the two inputs.

These functions allow not only to read and write unsigned values,
but also to check ranges and to emit trace output which can be
beautified when processing arrays (indices like "[i]" are replaced
by their actual numbers).
Yet lots of callers actually only need something simpler:
Their range is onl

Missing SEI information has always been a major drawback when using the QSV
decoders. I used to think that there's no chance to get at the data without
explicit implementation from the MSDK side (or doing something weird like
parsing in parallel). It turned out that there's a hardly known api metho

Attached patch adds input support for 16:9 DV video in QuickTime.
I found some old files produced by Adobe Premiere and Radius SoftDV which
were affected by this: 4:3 files were marked as type 'dvc ' which already
worked; 16:9 files as 'dvl ' which was missing. PAL uses 'p' in place of
the ' ' spa
