start time is already substracted from the frame timestamp, so it needs
to be checked against 0, not start time.

This avoids creating new AVStreams for them when switching between
different variants of them, since we can handle changes between
different sample rates of nellymoser within the same stream.

Fixes an invalid read on size change.

Currently it always exits with an error when more than
one position is specified.

Instead of inlining everything into ff_h264_hl_decode_mb(), use
explicit templating to create versions of the called functions
with constant parameters filled in.  This greatly speeds up
compilation of h264.c and reduces the code size without any
measurable impact on performance.

Compilation time for h264.c on an i7 goes from 30s to 5.5s.
Code size is reduced by 430kB.

Previously it was interpreted as number of bytes, while the
documentation stated that it was the number of 8 byte blocks.
This makes it behave similarly to the existing AES code.

Using ff_mspel_motion assumes that s (a MpegEncContext
poiinter) really is a Wmv2Context.

This fixes crashes in error resilience on vc1/wmv3 videos.

Should slightly improve performance depending on the compiler used.

Should slightly improve performance depending on the compiler used.

In certain conditions video or audio frames might appear way later in the
stream.

If the output frame size is smaller than the input sample rate,
and the input stream time base corresponds exactly to the input
frame size (getting input packet timestamps like 0, 1, 2, 3, 4 etc),
the output timestamps from the filter will be like
0, 1, 2, 3, 4, 4, 5 ..., leadning to non-monotone timestamps later.

A concrete example is input mp3 data having frame sizes of 1152
samples, transcoded to aac with 1024 sample frames.

By setting the audio filter time base to the sample rate, we will
get sensible timestamps for all output packets, regardless of
the ratio between the input and output frame sizes.

MSVC doesn't like the offsetof(..) >> 1 construct, it interprets it as
a non-literal, thus causing use of this in static tables to fail
compilation.

MSVC gives a compile error on the tentative definition of
mov_default_parse_table[].

All libs have version headers now, which allows hardcoding the path.

This avoids confusion from patterns meant to only match at the top
level matching files in subdirectories.
