62227a70f0 avformat: add av_stream_get_parser() to access avformat AVParser 
The AVStream.parser field is considered private and its location cannot be
preserved while preserving also ABI compatibility to libav, as libav added fields
before it.
Some tools like ffmpeg.c access this field though

650ef18078 avformat/utils: better probing for duration in estimate_timings_from_pts() 
It seems it is more secure to simply duplicate the computing routine from compute_pkt_fields to estimate_timings_from_pts.

194be1f43e lavf: switch to AVStream.time_base as the hint for the muxer timebase 
Previously, AVStream.codec.time_base was used for that purpose, which
was quite confusing for the callers. This change also opens the path for
removing AVStream.codec.

The change in the lavf-mkv test is due to the native timebase (1/1000)
being used instead of the default one (1/90000), so the packets are now
sent to the crc muxer in the same order in which they are demuxed
(previously some of them got reordered because of inexact timestamp
conversion).

5331773cc3 ff_id3v2_read: add option to limit ID3 magic number search 
Several chunked formats (AIFF, IFF,DSF) store ID3 metadata within an 'ID3 '
chunk tag. If such chunks are stored sequentially, it is possible for the
ID3v2 parser to confuse the chunk tag for the ID3 magic number. e.g.

[1st chunk tag ('ID3 ') | chunk size] [ID3 magic number | metadata ...]
[2nd chunk tag ('ID3 ') | chunk size] [ID3 magic number | metadata ...]

Fixes ticket #3530.

9f6f4962fb avformat/utils: dvd still frames read thru libdvdnav ended up in internal lavf buffer 
This is the solution we've been using in XBMC for over 2 years for dvd still frames.
The problem is that the demuxer asks for probing of the codec in the mpeg stream.
This causes lavf to read the whole menu structure into internal buffers.
After which, it won't read from input stream anymore and no events triggers.

86bee7984e AVFormatContext: add metadata_header_padding field 
This field is used to store the number of bytes that should be written
as padding to a metadata header of a file.  For example:
 - The FLAC format's METADATA_BLOCK_PADDING [1]
 - The ID3v2 tag format's padding           [2]

  lavf: Make probe_codec return an error code

Conflicts:

A failure to reallocate should not free the array as it is used
to probe the codec. And failure to reallocate if the following
probe succeeds isnt a fatal error for probe_codec(). Thus this
is only partially merged to ensure probing still is attempted
with the data available.

The check added in df33a58e53 does not work
at all, rather it broke the summing of bitrates completely.
The comparission was wrong way around.
This commit replaces it by a simpler and hopefully clearer check

37ecd67b5e Revert "avformat/utils: Close codec context since it is allocated by avformat_new_stream in refrence to ticket 2716" 
This causes a race condition with VLC. Its plausible that other
applications also would have races with it and its just fixing a memleak when
the user application forgets to free the codec. It causes more
problems than it solves in its current form, thus the revert.
Better solutions are welcome

This reverts commit 0f229f9b91.

says: "Something somehow does not look correct."

Since this message is most likely useful for debugging only, raise the
