This makes little sense due to how HLS works, and only causes some
additional annoyances if the HLS read_seek function fails (for example
if it's a live stream). It was most likely unintended.

Currently http end of chunk is signalled implicitly in dashenc_io_open().
This mean playlists http writes would have to wait upto a segment duration to signal end of chunk causing delays.
This patch will fix that problem and improve performance.

On systems which deliver SIGPIPE (Unices), a broken pipe will currently
result in the immediate termination of the ffmpeg process (the default
disposition as required by POSIX).  This is undesirable, because while
the broken pipe is likely fatal to useful cleanup of whatever component
is writing to it, there might be other components which can do useful
cleanup - for example, a muxer on another stream may still need to write
indexes to complete a file.  Therefore, set the signal disposition for
SIGPIPE to ignore the signal - the call which caused the signal will
fail with EPIPE and the error will be propagated upwards like any other
I/O failure on a single stream.

MediaSDK may fail to decode some frame, just skip it.
Otherwise, it will keep decoding the failure packet repeatedly
without processing any packet afterwards.

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.

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).

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
