Reduce audio fragment alignment jitter by penalizing alignment
correction offsets that deviate too much from the target offset.
This is accomplished by multiplying the cross correlation search
window with a quadratic function.

This way the filters which are semantically closer to the codec layer
have a (subjectively to me) more similar color.

The code in avfilter_copy_buf_props() is more generic, allow code
factorization.

Use av_frame_* accessors for the newly added fields in AVFrame (for which
we are supposed to use such accessors), and group the istructions
accordingly.

Mention av_image_copy() instead.

The documentation states that av_image_check_size() will return a
negative value in case of error, while the check is done on ret != 0.

Also return a proper error code rather than -1 in case the check fails.

about 2-5 times faster than gnu libcs qsort()
And should be 100% binary identical across platforms.

I will bump the version once the API is certainly stable and
everyone is happy with the API.

This requires all NAL units to fit within single RTP packets. It
doesn't change the actual packetization for packets that fit, but
errors out and gives a helpful hint if the NAL units would have to
be split, and signals the right packetization mode in the SDP.
