104f459258 qtdemux: fix key unit seek corner case 
If a key unit seek is performed with a time position that matches
the offset of a keyframe, but not its actual PTS, we need to
adjust the segment nevertheless.

For example consider the following case:

* stream starts with a keyframe at 0 nanosecond, lasting 40 milliseconds
* user does a key unit seek at 20 milliseconds
* we don't adjust the segment as the time position is "over" a keyframe
* we push a segment that starts at 20 milliseconds
* we push a buffer with PTS == 0
* an element downstream (eg rtponviftimestamp) tries to calculate the
  stream time of the buffer, fails to do so and drops it

4911ac38ac jpegdec: Don't dereference NULL input state if we have no caps in TIME segments 
Simply assume that the JPEG frame is not going to be interlaced instead
of crashing.

5fde140e6e qtdemux: implement support for trickmode interval

and TRICKMODE_KEY_UNITS was requested, only let through keyframes
separated with the required interval

436d33b288 splitmuxsink: add the ability to mux auxilliary video streams 
The primary video stream is used to select fragment cut points
at keyframe boundaries. Auxilliary video streams may be
broken up at any packet - so fragments may not start with a keyframe
for those streams.

b5d8484b0b splitmuxsrc: Add video_%d pad template. 
splitmuxsrc actually supports multiple video pads. Make that clear,
especially since it was already creating pads named "video_0" etc.

9deb3c27ac qtdemux: fix conditions for end of segment in reverse playback 
The time_position field of the stream is offset by the media_start
of its QtDemuxSegment compared to the start of the GstSegment of
the demuxer, take it into account when making comparisons.

9d9d543d5c rtpsession: Also send conflict event when sending packet

upstream event to tell the source to reconfigure itself.

Also ignore the collision if we see more than one collision from the same
remote source to avoid problems on loops.

b46dab13d2 rtph264pay: Support STAP-A bundling 
Add a new property "do-aggregate"* to the H.264 RTP payloader which
enables STAP-A aggregation as per [RFC-6184][1]. With aggregation enabled,
packets are bundled instead of sent immediately, up until the MTU size.
Bundles also end at access unit boundaries or when packets have to be
fragmented.

*: The property-name is kept generic since it might apply more widely,
   e.g. STAP-B or MTAP.
