This is a more sensible place for these macros.

Applications that have been linked against an older release of Libav and pick up
updated libraries experience segmentation faults because they pick up the new
libavfilter, which assumes AVFrames have been allocated by libavutil and thus
contain new reference-counting related fields. This will break for AVFrames that
have been allocated by old libavcodec.

All scheduled API changes are deferred to the next bump.

The function is used in a block of code that is deprecated anyway.

Before, it just returned width/height. Correct is width/height*sar.

That way it is consistent with DAR as in probe output and setdar.

Sometimes, if pthread_create() failed, then pthread_cond_wait() could
accidentally be called in the worker threads after the uninit function
had already called pthread_cond_broadcast(), leading to a deadlock.

Don't call pthread_cond_wait() if c->done is set.

The pixel format tables are never modified, mark them as constant.

When using AV_NOPTS_VALUE (which expands to INT64_C(0x8000000000000000))
as union initializer for a double field, the c99 converter needs to
interpret this constant when filling the union initializer, and it is
interpreted as a positive value.

When converting AV_NOPTS_VALUE to a double, MSVC 2010 ends up with
the same positive value as the c99 converter, while MSVC 2012 gets
a negative value.

This results in an infite loop in various FATE tests on MSVC 2012.

This allows for dropping or duplication to match a particular start time.

If any samples are still buffered when request_frame returns EOF, they
won't be returned currently.

This function should never modify the filter.

Also fix some similar typos in comments and documentation.

Previously it was partly only added to central functions called
internally, however if GCC would inline these into the public fuction, the
alignment attribute would not take effect.

Instead, add it to all public entry points to avoid these problems.

The generic code frees them as well. Since av_free was used to free them
instead of av_freep, this would result in a double free.

This simplifies the code and avoids using libavcodec-specific
avcodec_fill_audio_frame().

Mostly based on libavcodec's

Additionally change sizeof(type) into sizeof(var)

Use the formats.h API instead.
