c0550265e6 Revert "openjpegdec: support grayscale with alpha channel" 
This reverts commit 1883ac26b7.

This breaks the build on older versions of openjpeg:
gstopenjpegdec.c:752:30: error: ‘opj_image_comp_t {aka struct opj_image_comp}’ has no member named ‘alpha’

2b401de91c dashdemux: Implement a default presentation delay 
Have a fallback presentation delay is great (if not present in the
manifest), having an actual default value is better.

be465a139b dashdemux: Use correct (sub) fragment start when clipping chunk size 
If we didn't download anything yet, we shouldn't use fragment.start but
the start position of the current sidx entry.

d5eee31918 dashdemux: Make sure to pass the next buffer after a seek with DISCONT flag 
When we manually seek for skipping ahead in keyunit-only trickmode, we
have to enforce that ourselves as adaptivedemux does not know about the
seeks.

e2a6573c7d dashdemux: Smooth out skip distances in keyframe-only trick modes 
This ensures smoother playback. It looks weird if we first do a big
jump, then play a couple of consecutive frames, just to again skip ahead
quite a bit because we ran late again.

needed.

133d1e86bd dashdemux: Download keyframes from the current position if we're far enough ahead 
Far enough here means more than 500ms or 4 times the average keyframe
download time. There is no need to jump ahead by one average keyframe
download time in this case.

This makes playback smooth if the network is fast enough.

245d73e516 dashdemux: Improve key-unit trick mode downloading 
When dealing with key-unit trick mode downloads, the goal is to
provide the best "Quality of Experience". This is achieved by:
1) maximizing the number of frames displayed per second
2) avoiding "stalling" as much as possible (i.e. not downloading and
  decoding frames fast enough)

This implementation achives this by:
1) Knowing very precisely the current keyframe being download (i.e
  more accurate than at the fragment level which might contain more
  than one keyfram). This is the new "actual_position" variable
  introduced by this commit
2) Knowing the position of downstream (provided by QoS and stored
  in the adaptivedemuxstream qos_earliest_time variable)
3) Knowing how long it takes to request and fully download a keyframe
  (the average_download_time variable)

Taking those 3 variables into account, whenever a keyframe has been
pushed downstream we calculate a "target time" (target_time variable)
which is the ideal next keyframe time to request so that:
1) It will be requested/downloaded/demuxed/decoded in time to be
  displayed without being too late
2) It will not be too far ahead that it would cause too few frames
  per second to be displayed.

How far ahead we will request is inversily proportional to how close
the actual position (actual_position) is from the downstream
position (qos_earliest_time). The more is buffered between the source
and the sink, the "closer" the target time will be, and therefore
the more frames per seconds will be displayed (up to the limit
of keyframes_per_second * absolute_rate).
