Fred Rothganger 3f3229cd10 avformat: extracting NTP timestamp from RTCP
For muxing, it accepts
both 0 and AV_NOPTS_VALUE. For demuxing, it will present
AV_NOPTS_VALUE when start_time_realtime is unknown.

Luca Barbato d9ae1031f5 lavf: improve handling of sparse streams when muxing
Currently ff_interleave_packet_per_dts() waits until it gets a frame for
each stream before outputting packets in interleaved order.

Sparse streams (i.e. streams with much fewer packets than the other
streams, like subtitles or audio with DTX) tend to add up latency and in
specific cases end up allocating a large amount of memory.

Emit the top packet from the packet_buffer if it has a time delta
larger than a specified threshold.

Original report of the issue and initial proposed solution by
mus.svz@gmail.com.

Anton Khirnov 8b64c2ba03 lavc: add a dummy field to AVStream to preserve ABI compatibility for avconv
avconv abuses the API by accessing AVStream.parser (which is private).
Removing AVStream.reference_dts in

old avconv using a newer lavf. Fix this by adding a dummy field until
the next bump.

Michael Niedermayer f9d7431272 avformat/AVFormatContext: Move fields down to match the fork
avconv uses private and internal fields from libavformat, we thus must
match the layout even of the fields marked non public.
Otherwise ffmpegs libavformat could not be used as a dropin replacement
on debian/ubuntu

The current soname of libavformat was not part of any release nor are any
fields marked public moved thus in theory
no installed shared lib ABI breakage should occur. Still the need for this
change is unfortunate and chilling.
If you installed shared libs from a recent development version of libavformat
that is more recent than the last release. You probably want to check or rebuild
applications that linked to it.

minor versions of avformat & avdevice are bumped to allow detecting this
as both use the updated struct

Matthew Heaney bc35df29c1 lavf: add AV_DISPOSITION flags for WebVTT text track kinds
There are 4 separate WebVTT text track kinds: subtitles (the default
if not otherwise specified), captions, descriptions, and metadata.
The WebM muxer needs to know which WebVTT text track kind this is, in
order to synthesize the correct track type and codec id.

To allow a demuxer to indicate the text track kind of the input, a new
set of AV_DISPOSITION flag values has been added, corresponding to
each of the non-default text track kind values.
