Add some guards and fat warnings to the header files with still unstable
API, so people who just look at the installed headers know that it
actually is unstable API.
Also move schroedinger plugin. This creates a new library,
gstbasevideo-0.10, which will probably be merged back into
gstvideo-0.10 when this is moved back to -base.
- Separate gstsignalprocessor into a separate library (not sure if this
is in the right place, but it works for now anyway)
- Create LV2 element based on LADSPA element, port most discovery
functionality
Register xmp schemas for photoshop and iptc. Map a few location tags there.
Add more dc tags. Fix reading xmp tag by iteration over known schemas. Add
some more debug logging.
The gst_jack_audio_client_set_active() flags the port as deactivating and uses
a GCond to wait until the jack_process_cb() has run once more and cleared the
flag. This way the client zero's the buffer. This happens if one manyally go
to PAUSED and then to READY, while leting the mainloop run inbetween.
Enable creation of the demuxer pads for all audio streams, even types we
don't yet support. This means that unsupported types (LPCM, DTS) are output,
but not linked to anything yet. If only unsupported streams are available,
the user hears silence instead of having the pipeline not pre-roll correctly.
This is a prerequisite for hooking up the automatic decoder switching.
Re-work the dtsdec element code to unify it with changes made it a52dec,
including support for reverse playback and dynamic channel negotiation
on the source pad.
When updating a pad, send the update to half a second behind the SCR,
which avoids ever updating the start time for a pad to beyond the end of
the cell. Also, remember the last actual new-segment start time for each
pad, and use it when closing the segment.
When the current button number is higher than the number of available
buttons, switch to the highest numbered button rather than the lowest.
Also, don't throw errors when we fail to retrieve some button info
from libdvdnav, just reset the highlight.
Send the commands-changed navigation message when the set of available
DVD menu button actions changes, and handle the commands navigation
query so that (e.g.) Totem can know about the available navigation
commands.
Protect pad exposure with a preroll lock to avoid situations
where no-more-pads is fired more than once, or fired just before
the last pad is actually added.
Send segment updates to the audio and subpicture pads more frequently,
but less often to the video pad, where timestamps appear less often.
This helps with gap filling on some DVDs.
When creating a filler audio buffer in rsnaudiomunge, generate
a bit more, as audio sinks don't seem to preroll otherwise. This
needs a better algorithm in general, to intelligently fill the
gap, rather than hard-coding a value.
Make timed still frames work better by extending the current segment
when needed, and restarting the still sequence with the correct
remaining duration when the wait it interrupted by activation of a
highlight NAV packet.
The part number reported while in a menu doesn't reflect the selected
menu, so it's pointless to use it to report which menu we're in (Audio,
Angle etc). Just report "DVD Menu" in the title tag instead.
The logical audio and subpicture stream number doesn't always correspond
with the physical substream it is coming from. When configuring the demuxer
pads, use the mapping table provided in each PGC to get the layout and
ensure the demuxer creates the correct pads.
modplug's sndfile.h conflicts with libsndfile's sndfile.h, so
we'll access it directly using modplug/sndfile.h. Fixes#573849

No need to unref buffers if pad_push returns something non-FLOW_OK.
In fact, this will cause assertions or crashes. However, we do need
to unref the input buffer whenever we don't pass it downstream. Also,
a non-OK flow return is not an error, so don't post error messages on
the bus - the pipeline may just be shutting down. Miscellaneous other
clean-ups and crack removal. Plenty of work left for those who feel
like it.
When sending the stream change message(s) to the demuxer, also include the
logical stream id along with the physical ID, so that the demuxer can remap
logical->physical MPEG stream ID.
Handle the new DVD commands, so that we can handle commands from a player
to change angle, jump to menus etc. Use the new GstNavigation event parsing
functions, instead of hand-rolled stuff.
Send GstNavigation notification messages when the mouse enters a button
or leaves it, so UI can turn the mouse cursor to a hand icon.
Make the highlights re-appear correctly when jumping back into menus
by making sure to set the flushing_seek flag for user-action initiated
seeks.
Fiddle some debug related to tracking down the issue.
Add a workaround for an apparent libdvdnav bug where it loses nav packets
during multiangle titles, and add some keypress bindings to switch the angle.
