The alsamidisrc element allows to get input event from ALSA MIDI
sequencer devices, and possibly convert them to sound using some
downstream element like fluiddec.

These markers are visible in tools that record the GL function calls
such as apitrace, et al.
Makes it easier to match up GL draw commands with specific elements.
Ignore the normal gap threshold for laggy streams and
immediately catch all streams up to the end of the segment
when processing gap updates for a segment during a
still frame sequence.

An IDX file or codec_data normally contains the original frame size of
the video. Allow upstream to provide this information by sending a
custom event, which will allow scaling the overlay correctly.

Instead of only supporting writing SPU data directly to YUV frames,
render the SPU data to an intermediate AYUV overlay buffer. The overlay
data is then attached to the video frame if downstream supports overlay
composition, otherwise the AYUV overlay is blended to the video frame.
For the PGS format, the overlay buffer size is set to the size of the
Composition Window, and its position in the overlay composition is set
to the window position. The objects to render are now cropped when the
cropping flag is set.
For the Vobsub format, the overlay buffer size is set to the size of the
Display Area.
Once rendered, the overlay composition rectangle is now moved and scaled
to fit the video output size, to avoid clipping.

Create src pads for Representations that contain timed-text subtitles,
both when the subtitles are encapsulated in ISO BMFF (i.e., the
Representation has mimeType "application/mp4") and when they are
unencapsulated (i.e., the Representation has mimeType
"application/ttml+xml").

Otherwise they will receive a QOS event that has earliest_time=0 (because we
can't have negative timestamps), and consider their buffer as too late

The same has to be done for AdaptationSet and SegmentList nodes still.
Also this does not correctly implement the semantics: by default Period (and
other nodes) should only be loaded when needed, not in the very beginning. We
need to implement lazy loading for them, which means adjusting
gst_mpd_client_setup_media_presentation().

gst_uri_join_strings() will return the second parameter if it is an absolute
URI. No need to do a (wrong) check if the URI is absolute or not beforehand.
