69638517d1 lavf/segment: add increment_tc option 
For example you can split a file, keeping a continuous timecode between
each segment:
ffmpeg -i src.mov -timecode 10:00:00:00 -vcodec copy -f segment \
-segment_time 2 -reset_timestamps 1 -increment_tc 1 target_%03d.mov

14f7a3d55a lavc/lavf: transmit stream_id information for mpegts KLV data packets 
This allows to copy information related to the stream ID from the demuxer
to the muxer, thus allowing for example to retain information related to
synchronous and asynchronous KLV data packets. This information is used
in the muxer when remuxing to distinguish the two kind of packets (if the
information is lacking, data packets are considered synchronous).

The fate reference changes are due to the use of
av_packet_merge_side_data(), which increases the size of the output
packet size, since side data is merged into the packet data.

6c31c99289 hlsenc: add use_localtime_mkdir option to automatically create time-based directory 
Use with -use_localtime, and set -hls_segment_filename to a path which
contains a subdirectory i.e. /some/path/%Y%m%d/%Y%m%dT%H%M%S-%s.ts
This will mkdir the %Y%m%d-part of the path if it does not already
exist.
In addition, each filename in the playlist output will be prefixed with
this subdirectory (if playlist and segment shares the same base path).

9ba54c1b82 avcodec: Remove libaacplus 
TODO: bump minor

It's inferior in quality to fdk-aac and has an arguably more problematic
license.

As early as 2012, a HydrogenAudio user reported:

> It has however one huge advantage: much better quality at low bitrates than
> faac and libaacplus.

(https://hydrogenaud.io/index.php?PHPSESSID=ckiq394pdglka0kj2fin6ij8t7&topic=95989.msg804633#msg804633)

I myself have made a few spectrograms for a comparison of the two
encoders as well. The FDK output is consistently better than the
libaacplus one, in all bitrates I tested.

libaacplus license is 3GPP + LGPLv2. 3GPP copyright notice is completely
proprietory, as follows:

> No part may be reproduced except as authorized by written permission.
>
> The copyright and the foregoing restriction extend to reproduction in
> all media.

>
> All rights reserved.

(The latest 26410-d00 zip from 3GPP has the same notice, but the copyright
year is changed to 2015)

The copyright part of the FDK AAC license (section 2) is a copyleft
license that permits redistribution under certain conditions (and
therefore the LGPL + libfdk-aac combination is not prohibited by
configure):

This option can force the segmenter to only start a new segment if a packet
reaches the muxer within the specified duration after the segmenting clock
time, which makes it more resilient to backward local time jumps, such as leap
seconds or transition to standard time from daylight savings time.

9f61abc811 lavf: allow custom IO for all files 
Some (de)muxers open additional files beyond the main IO context.
Currently, they call avio_open() directly, which prevents the caller
from using custom IO for such streams.

This commit adds callbacks to AVFormatContext that default to
avio_open2()/avio_close(), but can be overridden by the caller. All
muxers and demuxers using AVIO are switched to using those callbacks
instead of calling avio_open()/avio_close() directly.

(de)muxers that use the URLProtocol layer directly instead of AVIO
remain unconverted for now. This should be fixed in later commits.

84110f4f77 libavformat/tcp.c : add send_buffer_size and recv_buffer_size options 
adds two new options that may be set via the dictionary:

- send_buffer_size
- recv_buffer_size

When present, setsockopt() is used with SO_SNDBUF and SO_RCVBUF to set
socket buffer sizes.  I chose to make send and receive independent
because buffering requirements are often asymmetric.

Errors in setting the buffer size mean the socket will use its
default, so they are ignored.

There is no sanity checking on values, as the kernel/socket layers
already impose reasonable limits if asked for something crazy.

Rationale for enlarging receive buffers is to reduce susceptibility
to intermittent network delays/congestion.  I added setting the send
buffer for symmetry.

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.
