efc7df6c1f lavc: preserve the original private data in avcodec_copy_context() 
If a non-NULL codec was passed to avcodec_alloc_context3(), private data
will be already allocated in dest.

c9281a01b7 lavf: drop the zero-sized packets hack 
There should not be any valid reason anymore for passing completely
empty packets to lavf.
OTOH side data-only packets can be useful.

0c1959b056 lavf: add AVFMT_FLAG_BITEXACT. 
Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's
codec context.

Using codec options inside lavf is fragile and can easily break when the
muxing codec context is not the encoding context.

It leverages the new hwaccel 1.2 features:

- get_buffer2 is never called
- the internal context is automatically initialized/deinitialized

Support the URL scheme where the playpath is in an RTMP URL is
passed as the slist argument and the app is given infront of the
query part of the URL:

rtmp://host[:port]/[app]?slist=[playpath]

(other arguments in the query part are stripped as they are not used)

3828eb8519 libfdk-aac: Relicense the library wrappers to 2-clause BSD 
This should make it possible for Fraunhofer to contribute to these
wrappers - they didn't want to contribute to code under LGPL2.1 with
the "or any later version" clause (which allowed using the code
under the LGPL3 license).

15fa856b82 libfdk-aacenc: Enable 7.1 channel encoding 
7.1(wide) and 7.1(wide-side) channel layouts are supported in
fdk-aac since the 0.1.3 release.

The earlier versions of fdk-aac didn't include any library
version defines in the public headers, thus checking for
the AACENCODER_LIB_VL0 define is enough to know that we're
building against a new enough version of fdk-aac.

This change includes contributions by Tim Walker,
Michael Niedermayer and Timothy Gu.

Changes the result of the lavf-asf test (and its associated seektest),
since 'msmpeg4v3' gets written instead of just 'msmpeg4'.
