Enables getting access to ID3 PRIV tags from the command-line or metadata API
when demuxing. The PRIV owner is stored as the metadata key prepended with
"id3v2_priv.", and the data is stored as the metadata value. As PRIV tags may
contain arbitrary data, non-printable characters, including NULL bytes, are
escaped as \xXX.
Similarly, any metadata tags that begin with "id3v2_priv." are inserted as ID3
PRIV tags into the output (assuming the format supports ID3). \xXX sequences in
the value are un-escaped to their byte value.

If somebody else wants to maintain dashenc either now or in future,
I am absolutely fine with giving up this responsibility anytime.
But till then we need a maintainer for dashenc, and I am volunteering for that task.

Fixes a warning on ppc:
libavcodec/svq3.c:1055:21: warning: passing argument 1 of ‘av_write_bswap32’ discards 'const' qualifier from pointer target type
1 Add function 'resolve_content_path' to propagate the baseURL from
upper level nodes.
* if no baseURL is available, the path of mpd file will be set as the baseURL.
2 Remove checking for newly established connection.
3 Establish the communication protocol in each connection rather than
applying one protocol to all connection.
If no representation bandwidth value is set, the url value returned
by get_content_url is corrupt (as it has been freed).
This change ensures the url string is not freed unless it is about
to be reused
Changes since v1:
1 removed the unneeded 'if' statement (as pointed out by Michael Niedermayer
2 added comment to make it clear why the av_free was required

If codecpar->extradata is not set (for example, when the stream goes
through the 'tee' muxer), then a segfault occurs.
This patch ensures the data variable is not null before attempting
to access it
Before the var_stream_map option was available - I was using the tee
muxer to create each resolution as an individual stream.
When running this configuration after the most recent hlsenc change
I hit a segfault
The most simple command which recreates the segfault is:
ffmpeg -i in.ts -map 0:a -map 0:v -c:a aac -c:v h264 -f tee [select=\'a,v\':f=hls]tv_hls_hd.m3u8

During the initialization stage, the codec attempts to get free
buffers from the driver before any have been queued (this is to keep
the code simple and generic)
When the kernel driver detects this situation, it returns POLLERR in
revents and ffmpeg therefore raises a warning.
This commit disables the warning since no buffers were queued to the
driver yet.

Qualcomm's db410c/db820 Venus driver currently present in mainline
kernel has a bug which mishandles the CMD_STOP requests causing the
decoder to block while draining [1].
This patch removes the workaround that was used to prevent that
situation.
Encoding/Decoding tested on db820c.
[1] on CMD_STOP, the driver is flushing all buffers and never raising
IPIPE which ends up in blocking on poll.
Refcount all of the context information. This also fixes a potential
segmentation fault when accessing freed memory (buffer returned after
the codec has been closed).

There are 32 pseudo-instructions for each floating-point comparison
instruction, but only 8 of them are actually valid in legacy-encoded mode.
The remaining 24 requires the use of VEX-encoded (v-prefixed) instructions
and can therefore be disregarded for this purpose.
Clang applies the missing-prototypes warning on C++ files, whereas
gcc only applies it to C. As a result, the decklink_common.cpp file
fails to build because of missing prototypes in DecklinkDispatch.cpp
(which is #included by decklink_common.cpp).
We don't want to change the actual Blackmagic SDK sources, so
suppress the warning just for that one #include.
