It was never used since it was added and the things it was intended for
are now exported differently.

Currently ff_interleave_packet_per_dts() waits until it gets a frame for
each stream before outputting packets in interleaved order.

Sparse streams (i.e. streams with much fewer packets than the other
streams, like subtitles or audio with DTX) tend to add up latency and in
specific cases end up allocating a large amount of memory.

Emit the top packet from the packet_buffer if it has a time delta
larger than a specified threshold.

Includes a libavcodec utility function to update a frame's side data.

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.

Commit 41578f70cf changed the LLS API, which was
called from libavcodec. Thus using an old libavcodec with a new libavutil will
break.

All scheduled API changes are deferred to the next bump.

Also bump libavcodec micro and add an APIchanges entry saying that
av_frame_* should now be used instead of the lavc AVFrame functions.

We will likely want to add new fields to it in the future, so this is
needed to avoid breaking ABI.

This can be optionally disabled whith the "output_corrupt" flags
option.  When in "output_corrupt" mode, incomplete frames are
signalled through AVFrame.flags FRAME_FLAG_INCOMPLETE_FRAME.

Also fix the typo in the last entry version.

Provide a clean way to manipulate packets.

The bitstream buffers are now private and freed by libavcodec. For
backward compatibility, the hold bitstream buffer pointer is left NULL
(applications were supposed to av_freep() it).

Mostly based on libavcodec's

It will be useful in lavfi, and could conceivably be useful to the user
applications as well.

Fixes Bug 378.

Removes an arbitrary hardcoded limit on the number of filters.

The caller needs to know what valid indices can be passed to
avfilter_pad_get_name/type.

This will be useful in avtools in the following commits.
Any other caller might also want to know this information.

Drop the unused opaque parameter from its signature.

It will be useful in the following commits.

Since this function adds a standalone filter to a filter graph and we do
not support creating such filters, there is no reason for this function
to exist.
