933dec0e29 file: Add an option for following a file that is being written
Using this requires setting the rw_timeout option to make it
terminate, alternatively using the interrupt callback (if used via
the API).

ccea588f83 avio: Add an option 'rw_timeout'
If set non-zero, this limits duration of the retry_transfer_wrapper()
loop, thus affecting ffurl_read*(), ffurl_write(). As soon as
one single byte is successfully received/transmitted, the timer
restarts.

This has further changes by Michael Niedermayer and Martin Storsjö.

9200514ad8 lavf: replace AVStream.codec with AVStream.codecpar
Currently, AVStream contains an embedded AVCodecContext instance, which
is used by demuxers to export stream parameters to the caller and by
muxers to receive stream parameters from the caller. It is also used
internally as the codec context that is passed to parsers.

In addition, it is also widely used by the callers as the decoding (when
demuxer) or encoding (when muxing) context, though this has been
officially discouraged since Libav 11.

There are multiple important problems with this approach:
    - the fields in AVCodecContext are in general one of
        * stream parameters
        * codec options
        * codec state
      However, it's not clear which ones are which. It is consequently
      unclear which fields are a demuxer allowed to set or a muxer allowed to
      read. This leads to erratic behaviour depending on whether decoding or
      encoding is being performed or not (and whether it uses the AVStream
      embedded codec context).
    - various synchronization issues arising from the fact that the same
      context is used by several different APIs (muxers/demuxers,
      parsers, bitstream filters and encoders/decoders) simultaneously, with
      there being no clear rules for who can modify what and the different
      processes being typically delayed with respect to each other.
    - avformat_find_stream_info() making it necessary to support opening
      and closing a single codec context multiple times, thus
      complicating the semantics of freeing various allocated objects in the
      codec context.

Those problems are resolved by replacing the AVStream embedded codec
context with a newly added AVCodecParameters instance, which stores only
the stream parameters exported by the demuxers or read by the muxers.

1f9139b07b lavf: add automatic bitstream filtering; bump version
This solves the problem discussed in https://ffmpeg.org/pipermail/ffmpeg-devel/2015-September/179238.html
by allowing AVCodec::write_header to be delayed until after packets have been
run through required bitstream filters in order to generate global extradata.

It also provides a mechanism by which a muxer can add a bitstream filter to a
stream automatically, rather than prompting the user to do so.

0f87cbdd51 lavf: add oggparsedaala and bump micro
This commit introduces a parser for the current bitstream produced by
Daala. It currently bears a large similarity with Theora, another
codec produced by Xiph. While likely to change in the future, its basic
format of packet parsing should remain fairly identical with its current
structure.
Once the bitstream freezes, there are a few probable simplifications
that could be made. Also, the current version (major, minor and micro)
is stuck at zero so it's unusable as a way to warn about possible
incompatibilities. This will change once the bitstream freezes,
however until then this file is strictly targeting the current git
master of the reference encoder, libdaala.

This file was developed independently at the same time by both myself
and Vittorio Giovara, who used libav as a starting point. For fairness,
and to prevent confusion and allegations, his name has been added to the
copyright in the license header as well, and vice versa.

b08569a239 lavf: Replace the ASF demuxer
The old one is the result of the reverse engineering and guesswork.
The new one has been written following the now-available specification.

This work is part of Outreach Program for Women Summer 2014 activities
for the Libav project.

The fate references had to be changed because the old demuxer truncates
the last frame in some cases, the new one handles it properly.
The seek-test reference is changed because seeking works differently
in the new demuxer. When seeking, the packet is not read from the stream
directly, but it is rather constructed by the demuxer. That is why
position is -1 now in the reference.

414d6547f3 mov: Add option to keep exact packet sequence after seeking
The current behavior may produce a different sequence of packets
after seeking, compared to demuxing linearly from the beginning.
This is because the MOV demuxer seeks in each stream individually,
based on timestamp, which may set each stream at a slightly different
position than if the file would have been read sequentially.

This makes implementing certain operations, such as segmenting,
quite hard, and slower than need be.

Therefore, add an option which retains the same packet sequence
after seeking, as when a file is demuxed linearly.

847bf5988f movenc: Add an option for delaying writing the moov with empty_moov
This delays writing the moov until the first fragment is written,
or can be flushed by the caller explicitly when wanted. If the first
sample in all streams is available at this point, we can write
a proper editlist at this point, allowing streams to start at
something else than dts=0. For AC3 and DNXHD, a packet is
needed in order to write the moov header properly.

This isn't added to the normal behaviour for empty_moov, since
the behaviour that ftyp+moov is written during avformat_write_header
would be changed. Callers that split the output stream into header+segments
(either by flushing manually, with the custom_frag flag set, or by
just differentiating between data written during avformat_write_header
and the rest) will need to be adjusted to take this option into use.

For handling streams that start at something else than dts=0, an
alternative would be to use different kinds of heuristics for
guessing the start dts (using AVCodecContext delay or has_b_frames
together with the frame rate), but this is not reliable and doesn't
necessarily work well with stream copy, and wouldn't work for getting
the right initialization data for AC3 or DNXHD either.

8a70ef94b9 libavformat: Add a muxer wrapping mpegts encoding into RTP
Since this structurally is quite different from normal RTP
(multiple streams are muxed into one single mpegts stream,
which is packetized into one single RTP session), it is kept
as a separate muxer.

Since this structurally also behaves differently than normal
RTP, all of the other muxers that do chained RTP muxing
(rtsp, sap, mp4) would need to be updated similarly to handle
this - in particular, creating one single rtp_mpegts muxer
for the whole presentation instead of one rtp muxer per stream.

a505c0d737 rtp: Initial H.261 support
The packetizer only supports splitting at GOB headers - if
such aren't available frequently enough, it splits at any
random byte offset (not at a macroblock boundary either, which
would be allowed by the spec) and sends a payload header pretend
that it starts with a GOB header.

As long as a receiver doesn't try to handle such cases cleverly
but just drops broken frames, this shouldn't matter too much
in practice.

500d608861 lavf/ffmenc: store recommended encoder configuration
ffmenc will store recommended encoder configuration if present.
This will allow the user to base on local defaults and
apply only explicitly set options.

If recommended encoder configuration is not present, then
non-default context's options are stored.

fe5e6e34c0 lavf: Add an MPEG-DASH ISOFF segmenting muxer
This is mostly to serve as a reference example on how to segment
the output from the mp4 muxer, capable of writing the segment
list in four different ways:
- SegmentTemplate with SegmentTimeline
- SegmentTemplate with implicit segments
- SegmentList with individual files
- SegmentList with one single file per track, and byte ranges

The muxer is able to serve live content (with optional windowing)
or create a static segmented MPD.

In advanced cases, users will probably want to do the segmenting
in their own application code.

2ded57371a movenc: Add support for writing sidx atoms for DASH segments
A flag "dash" is added, which enables the necessary flags for
creating DASH compatible fragments.

When this is enabled, one sidx atom is written for each track
before every moof atom.

1384df6419 lavf: Add an option for avoiding negative timestamps
This is the same logic as is invoked on AVFMT_TS_NEGATIVE,
but which can be enabled manually, or can be enabled
in muxers which only need it in certain conditions.

Also allow using the same mechanism to force streams to start
at 0.
