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.

Current code divides before increasing precision.
Also reduce upper bound for strength from 255 to 64. This will prevent
an overflow in the SSSE3 and MMX filter_line code: delta is expressed as
an u16 being shifted by 2 to the left. If it overflows, having a
strength not above 64 will make sure that m is set to 0 (making the
m*m*delta >> 14 expression void).
A value above 64 should not make any sense unless gradfun is used as
a blur filter.

- Make MultiByteToWideChar fail when it encounters invalid encoding.
Without this, invalid characters might just be skipped
- When MultiByteToWideChar fails, assume the file name is in CP_ACP
and open it via normal open function, even when the file will be
written
- When malloc fails return error instead of crashing

In order to match Linux behaviour better our Windows-specific
open() replacement should disable Windows default file locking.

This makes standalone compilation of the eatqi decoder
succeed. The dependency comes from the shared mpeg12dec.o file.

This fixes standalone compilation of the msmpeg4v2, msmpeg4v3
and wmv2 encoders, that previously failed to link due to the
decoder codepaths requiring error_resilience.

Allows use of AVHWAccel based decoders with frame based multithreading.
The decoders will be forced into an non-concurrent mode by delaying
ff_thread_finish_setup() calls after decoding of the current frame
is finished.
This wastes memory by unnecessarily using multiple threads and thus
copies of the decoder context but allows seamless switching between
hardware accelerated and frame threaded software decoding when the
hardware decoder does not support the stream.
Since c977039e58 plane count for
PIX_FMT_HWACCEL pixel formats is 0 instead of 1. The created dummy
AVBuffers are still bogus since AVFrame does not hold frame data when
AVHWAccels are used.
Error resilience is enabled by the h264 decoder, unless explicitly
disabled. --disable-everything --enable-decoder=h264 will produce
a h264 decoder with error resilience enabled, while
--disable-everything --enable-decoder=h264 --disable-error-resilience
will produce a h264 decoder with error resilience disabled.
