Ignore empty language codes on some poorly coded DVDs, rather than
setting empty strings into our outgoing taglist.
|
|
|
|
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.
|
|
Fix the same bug as the previous commit, but in resindvd's copy of
mpegdemux.
|
|
Make sure we send events to all pads. Unmark the notlinked flag on
freshly selected pads to ensure they get data.
|
|
Restore the old segment update behaviour, and instead extend the
close segment stop time if the SCR (last_stop) overruns the calculated
stop position.
|
|
|
|
Make the debug statement correctly show the 'old' and 'new' button
coordinates, instead of the wrong way around.
|
|
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.
|
|
Make sure we always show information about the segment events passing through,
even when pre-roll audio buffers aren't going to be needed.
|
|
Rename a debug category: rsn_audiomunge -> rsnaudiomunge.
|
|
|
|
Skip attempting to schedule a nav block unless we're in PLAYING. Take a lock
slightly later, when we actually need it. Remove a noisy LOG message.
|
|
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.
|
|
Make sure we send an update title tag when the current angle or available
angles changes.
|
|
Send messages when the available DVD navigation commands changes, and
handle navigation commands and angles queries.
|
|
Load each VTS ifo the first time the disc enters that VTS,
rather than scanning them all at the start.
|
|
Allow apps like Totem to display a nicer title that reflects the current
position on the disc.
|
|
Fix a small bug that results in the SPU highlight being reset more often
than is necessary - ie, clearing it when it's already cleared.
|
|
When the current angle changes, or the number of available angles changes,
send an angles-changed message to let the app know.
|
|
When the current angle is 1 and prev_angle is requested, loop to the
maximum angle and vice versa for next_angle
|
|
Trim down the g_print verbosity.
|

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.
|
|
Fixes #577864.
|
|
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.
|
|
Change the pad blocking behaviour during startup, and use a hard-coded mpeg2dec (for the moment), in order to make things work with playbin2.
|
|
|
|
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.

Add a 'fast-start' property to the rsndvdsrc element, that attempts to
jump directly to the DVD menu when starting. Doesn't work correctly on all
titles yet.
Add workarounds for issues with multiple angles in libdvdnav: Use a heuristic
to avoid detecting discontinuities during multiple-angle titles, it seems
caused by libdvdnav losing some NAV packets in multiangle titles. Fix
seeking in multi-angle titles by aligning our sector calculation logic
with libdvdnav's. Also, use libdvdnav's dvdnav_get_current_time() method
to determine the logical position of the current cell when it changes, as the
cell_start value in the cell_change event provides a number that doesn't
compensate for angle cell blocks.
