In the non-bitexact mode, vp3 currently decodes to the same
frame crcs as before 28f9ab70 (and the output visually looks
correct).

Unrolling and not storing mask both save some cycles.

The gcov/lcov are a common toolchain for visualizing code coverage with
the GNU/Toolchain. The documentation and implementation of this
integration was heavily inspired from the blog entry by Mike Melanson:
http://multimedia.cx/eggs/using-lcov-with-ffmpeg/

There is no arch-optimized version of the H.261 loop filter and there
likely will never be, so the dsputil overhead does not give any benefit.

It can be 0 or -1 for invalid files, which may result in invalid memory
access.

This can happen when the number of skipped lines is not consistent with
the number of coded lines.

Make sure we notice when the lace_size[n] is a negative value.

The previous syntax is deprecated.

Avoid snprintfing a NULL pointer.

The "suncc" atomics implementation uses a suncc specific memory
barrier, but also relies on a few atomic functions from atomic.h,
that are not suncc specific but specific to solaris. This made
the current implementation fail on suncc on linux.

Add simpler names and a shorthand for native atomics (as opposed to
pthreads fallback).

The sample rate index is 3 bits even if currently index 5, 6 and 7 are
not supported.

Only deprecated things need this at all anymore, as we have functions
to access them or they are no longer needed.

The document should not encourage use of deprecated APIs.
