d9ae1031f5 lavf: improve handling of sparse streams when muxing
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.

Original report of the issue and initial proposed solution by
mus.svz@gmail.com.

645c94b61b Revert "Merge commit '3bc2e89c76e88ae6f1fd5287e0b11abcfc3c601c'" (Bump libavutil major version to account for the LLS API/ABI changes.)
This reverts commit 792845e436, reversing
changes made to 1d6666a6b8.

Bumping libavutil requires all libraries that use libavutil to have their
major version bumped (yes breakage has been confirmed this is not a hypotheses)

One case of breakage is due to new types being added to AVOptions and
applications that linked to old libavutil and libswresample
then trying to use old libavutil (its soname changed so the old isnt updated)
and new swresample (its soame didnt change so it is updated)
the new swresample contains AVOption types that the old libavutil doesnt
know of thus the application attempting to access these avoptions
fails

AVOptions are used by all libs so the issue can potentially happen with
any other lib, libswresample was just the first that showed the problem
ive not checked if the other libs are affected currently by the same issue
or not

Also in addition to AVOptions, AVFrames are also defined in
libavutil, bumping it without all libs that use AVFrames could lead to
serious inconsistencies when 2 libs/app end up using 2 different libavutils

The alternative of bumping all is still possible after this revert, if it
turns out to be the preferred solution

6d3ea1957f Bump major of libavfilter for reference counted buffer API changes.
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.

3bc2e89c76 Bump libavutil major version to account for the LLS API/ABI changes.
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.

  libraries'.
* Avoids file name clash between FFmpeg's ./version.h and lib*/version.h when
  a library source file includes both and is compiled on an out-of-tree build.

Fixes #1769.

d404fe35b2 Make new VDPAU easier to use by adding context to callback.
Using VDPAU correctly means checking for preemption
and possibly regenerating the context all the time.
With the current API there is no context or other
user-defined pointer and thus this in not possible
during decoding unless using some hack like global
variables.
The need to reinitialize both surfaces and even function
pointers makes handling preemption even more difficult.
This patch introduces a new render2 function that gets
both the AVCodecContext and AVFrame in addition,
in both the user can store additional opaque data.
This allows even advanced approaches like keeping a
"generation counter" for the surfaces so they can be
regenerated on the fly and efficiently.
In addition, the function has a return value that will
be passed through all the way instead of being silently
ignored as for the current render function.
Unfortunately the HWAccel API has no way of providing
API/ABI compatibility, so a currently disallowed
state (render pointer being NULL) is used to extend it.

If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the

At the next major bump the current implementation of
avfilter_graph_parse() should be dropped in favor of the Libav/old

There are 4 separate WebVTT text track kinds: subtitles (the default

The WebM muxer needs to know which WebVTT text track kind this is, in
order to synthesize the correct track type and codec id.

To allow a demuxer to indicate the text track kind of the input, a new
set of AV_DISPOSITION flag values has been added, corresponding to
each of the non-default text track kind values.

7c1a002c78 subtitles: introduce ASS codec id and use it.
Currently, we have a AV_CODEC_ID_SSA, which matches the way the ASS/SSA
markup is muxed in a standalone .ass/.ssa file. This means the AVPacket
data starts with a "Dialogue:" string, followed by a timing information
(start and end of the event as string) and a trailing CRLF after each
line. One packet can contain several lines. We'll refer to this layout
as "SSA" or "SSA lines".

In matroska, this markup is not stored as such: it has no "Dialogue:"
prefix, it contains a ReadOrder field, the timing information is not in
the payload, and it doesn't contain the trailing CRLF. See [1] for more
info. We'll refer to this layout as "ASS".

Since we have only one common codec for both formats, the matroska
demuxer is constructing an AVPacket following the "SSA lines" format.
This causes several problems, so it was decided to change this into
clean ASS packets.

Some insight about what is changed or unchanged in this commit:

  CODECS
  ------

  - the decoding process still writes "SSA lines" markup inside the ass
    fields of the subtitles rectangles (sub->rects[n]->ass), which is
    still the current common way of representing decoded subtitles
    markup. It is meant to change later.

  - new ASS codec id: AV_CODEC_ID_ASS (which is different from the
    legacy AV_CODEC_ID_SSA)

  - lavc/assdec: the "ass" decoder is renamed into "ssa" (instead of
    "ass") for consistency with the codec id and allows to add a real
    ass decoder. This ass decoder receives clean ASS lines (so it starts
    with a ReadOrder, is followed by the Layer, etc). We make sure this
    is decoded properly in a new ass-line rectangle of the decoded
    subtitles (the ssa decoder OTOH is doing a simple straightforward
    copy). Using the packet timing instead of data string makes sure the
    ass-line now contains the appropriate timing.

  - lavc/assenc: just like the ass decoder, the "ssa" encoder is renamed
    into "ssa" (instead of "ass") for consistency with the codec id, and
    allows to add a real "ass" encoder.

    One important thing about this encoder is that it only supports one
    ass rectangle: we could have put several dialogue events in the
    AVPacket (separated by a \0 for instance) but this would have cause
    trouble for the muxer which needs not only the start time, but also
    the duration: typically, you have merged events with the same start
    time (stored in the AVPacket->pts) but a different duration. At the
    moment, only the matroska do the merge with the SSA-line codec.

    We will need to make sure all the decoders in the future can't add
    more than one rectangle (and only one Dialogue line in it
    obviously).

  FORMATS
  -------

  - lavf/assenc: the .ass/.ssa muxer can take both SSA and ASS packets.
    In the case of ASS packets as input, it adds the timing based on the
    AVPacket pts and duration, and mux it with "Dialogue:", trailing
    CRLF, etc.

  - lavf/assdec: unchanged; it currently still only outputs SSA-lines
    packets.

  - lavf/mkv: the demuxer can now output ASS packets without the need of
    any "SSA-lines" reconstruction hack. It will become the default at
    next libavformat bump, and the SSA support will be dropped from the
    demuxer. The muxer can take ASS packets since it's muxed normally,
    and still supports the old SSA packets. All the SSA support and
    hacks in Matroska code will be dropped at next lavf bump.

6fb2fd895e lavc: add lavfi metadata support.
This commit introduces a new AVPacket side data type:
AV_PKT_DATA_STRINGS_METADATA. Its main goal is to provide a way to
transmit the metadata from the AVFilterBufferRef up to the AVFrame. This
is at the moment "only" useful for lavfi input from libavdevice:
lavd/lavfi only outputs packets, and the metadata from the buffer ref
kept in its context needs to be transmitted from the packet to the frame
by the decoders. The buffer ref can be destroyed at any time (along with
the metadata), and a duplication of the AVPacket needs to duplicate the
metadata as well, so the choice of using the side data to store them was
selected.

Making sure lavd/lavfi raises the metadata is useful to allow tools like
ffprobe to access the filters metadata (it is at the moment the only
way); ffprobe will now automatically show the AVFrame metadata in any
customizable output format for users. API users will also be able to
access the AVFrame->metadata pointer the same way ffprobe does
(av_frame_get_metadata).

All the changes are done in this single commit to avoid some memory
leaks: for instances, the changes in lavfi/avcodec.c are meant to
duplicate the metadata from the buffer ref into the AVFrame. Unless we
have an internal way of freeing the AVFrame->metadata automatically, it
will leak in most of the user apps. To fix this problem, we introduce
AVCodecContext->metadata and link avctx->metadata to the current
frame->metadata and free it at each decode frame call (and in the codec
closing callback for the last one). But doing this also means to update
the way the tiff decoder already handles the AVFrame->metadata (it's the
only one decoder with frame metadata at the moment), by making sure it
is not trying to free a pointer already freed by the lavc internals.

The lavfi/avcodec.c buffer ref code is based on an old Thomas Kühnel
work, the rest of the code belongs to the commit author.

Make av_pix_fmt_descriptors table static on next major bump.

Making the table public is dangerous, since the caller has no way to
know how large it actually is. It also prevents adding new fields to
AVPixFmtDescriptor without a major bump.

9a92aea27b avutil: Add functions for allocating opaque contexts for algorithms
The current API where the plain size is exposed is not of much
use - in most cases it is allocated dynamically anyway.

If allocated e.g. on the stack via an uint8_t array, there's no
guarantee that the struct's members are aligned properly (unless
the array is overallocated and the opaque pointer within it
manually aligned to some unspecified alignment).
