xHE-AAC is a profile where some frames depend on other key frames, named IPF.
By setting the codec as Intra Only, all frames output by decoders and all
packets output by encoders/demuxers will be unconditionally flaged as
keyframes, which is incorrect.
Should fix ticket #11272.

And not just the first, as it was being done for lacing. The spec states that the
flag applies to everything inside the simple box.

The ctxi_dst variable is unused outside of the av_assert1,
causing an unused variable warning. The simplest solution
for this is to avoid the intermediate variable here.
They are needed for audio tracks with priming samples, where negative CTS
offsets can't be used.
Fixes ticket #11031.

avgBitrate == 0 is used to signal a VBR track, so if that value is propagated by an
encoder, don't overwrite it with a calculated value based on track size.

This avoids unpleasant surprises to av_frame_get_buffer callers
that explicitly specified 64-byte alignment and didn't get
AVFrame.data pointers that are 64-byte aligned.
For example, see https://github.com/sekrit-twc/zimg/issues/212
Although the zscale issue has already been resolved by other means
it would still be prudent to improve the behavior of av_frame_get_buffer
to fix any unknown and future instances of similar issues.

STRIDE_ALIGN is a lavc define and is not necessarely 32. And align may be <= 0 at the

This is a preliminary step to separating these into a new struct. This
commit contains no functional changes, it is a pure search-and-replace.

Some mp3 files look surprisingly like mpeg PS streams. In order for us
to hint to ffmpeg that the file really is mp3, we can deliver it with a
mime type. The mp3 probe therefore needs to have a mime type registered,
(which is previously did not).
For example, with
./ffmpeg -operating_rate 400 -hwaccel mediacodec -i test.mp4 -an \
-c:v h264_mediacodec -operating_rate 400 -b:v 5M -f null -
The transcoding speed is 254 FPS.
Without -operating_rate on dec/enc, the speed is 148 FPS.
With -operating_rate on decoder only, the speed is 239 FPS.

The codec wants to know whether the usecase is realtime playback
or full-speed transcoding, or playback at a higher speed. The codec
runs faster when operating_rate higher than framerate.

The code used as a basis was the buffer dependency code, where the
counter was incremented after each buffer, but for the sw_frame dep
API, we only support adding individual frames at a time.
