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:

(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

This option can force the segmenter to only start a new segment if a packet

time, which makes it more resilient to backward local time jumps, such as leap

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.

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.
