2020-06-19Make Atmos content work more like other content. Now its MXFsv2.15.82Carl Hetherington
are re-written, meaning that they can be encrypted. This (along with the libdcp update) also fixes assorted Atmos bugs.
2020-05-11Change video content scaling so that it either:Carl Hetherington
1. scales the content up to fit the DCP container, preserving aspect ratio, or 2. stretches the content to a custom aspect ratio, or 3. scales the content to some custom size.

2020-04-15Fix length of player output so it can be either the film's length or ↵Carl Hetherington
playlist's length, as appropriate.
2020-01-28Missing #include for previous.Carl Hetherington
2020-01-28Fix deadlock during content examination.Carl Hetherington
Before this fix, the following situation could happen in threads A and B: A: Some DONE signal happens; this triggers setup_pieces which takes a lock on the player mutex. B: FFmpegContent::examine takes a lock on the content mutex. B: FFmpegContent::examine adds a stream B: That causes STREAMS PENDING to be emitted. B: This tries to take a lock on the player mutex so it can update _suspended A: setup_pieces tries to access some content information, hence tries to take a lock on the content mutex. Now B is holding the CL and awaiting the PL and A is holding the PL and awaiting the CL. It feels like the root cause of this is that while setup_pieces is happening another change (which would itself cause setup_pieces) is announced, and this isn't dealt with properly. There are two steps here; _suspended is protected with an atomic rather than using _mutex, and also it can cope with being updated recursively.

2019-10-13Fix failure to load OV after adding a VF to a project.Carl Hetherington
This has the same cause as 19f51503621a57794bd79bac053c9e6549a69f46 i.e. the DCPDecoder re-use optimisation. This commit tries to re-fix 19f515 in a more general way which also takes into account the OV/VF bug. It also adds a unit test.

2018-09-04Build Empty objects from the presence or absence of decoders inCarl Hetherington
Pieces, rather than the presence or absence of content. This seems better because of cases like encrypted DCPs without a a KDM: here we may have content but no decoder.

2018-08-29Basics of splitting CCAP streams into different assets.Carl Hetherington

the content.
2018-08-19Similar pending/done for Film::Change.Carl Hetherington
2018-08-19Replace May/Done/NotDone signal sets with one signal and extendCarl Hetherington
this treatment to anything that caused Player::setup_pieces. This should fix out-of-sequence Player emissions caused by setup_pieces being called by one thread while the butler is calling pass().
2018-08-19Suspend butler on player may-change as otherwise there's a windowCarl Hetherington
between Player::_suspended being set to false and the the butler requesting a seek, during which the butler may call pass().
2018-08-14More fixes for errors / crashes / misbehaviour with content changesCarl Hetherington
and the butler. Here we signal both before and after a change in content. Before, the player disables itself so that any pass()/seek() will be no-ops. After, the player rebuilds its pieces and the butler re-seeks to get back to where it was before the change.
2018-08-10Use more direct route to fix hangs after calling some Player methods.Carl Hetherington
2018-08-10Try to fix Windows build.Carl Hetherington
2018-08-10Add some Changed() emissions so that when a butler is in controlCarl Hetherington
we always do a seek when we set _have_valid_pieces to false.
2018-08-05Get closed caption view data from the butler, rather than the player.Carl Hetherington
You can't introduce the butler (so that the player is ahead of time) and then ask the player what should be in the frame that is being displayed "now"; the player will already have moved on.

2018-07-26Protect the public API of Player with a mutex, sinceCarl Hetherington
seek() and pass() may be called from the Butler thread ad the same time as other Player methods are called from the GUI thread (by FilmViewer and ClosedCaptionViewDialog).

2018-07-23Get ccaps by asking the Player, rather than by listening to its emissions,Carl Hetherington

2018-06-29Basic jump to selected subtitle (#1200).Carl Hetherington
2018-02-24Speed some operations by re-using the last PlayerVideo but withCarl Hetherington
updated metadata (where possible). Helps with #1194.
2018-02-23Fix implementation of delay in 7758260; it needs to apply toCarl Hetherington
anything passed to emit_video(), not just things that come from decoders.
2018-02-20Add a 2-frame `delay' on content arriving at the player to giveCarl Hetherington
subtitle content the chance to catch up. Fixes problems observed when overlaying a DCP subtitle onto an existing DCP and then seeking into the first subtitle. After the seek the decoder positions were: DCP: 0. subtitle: first subtitle time. This causes the DCP decoder to be pass()ed first and so the subtitle for the video frame has not arrived yet. I hope this does not cause unpredicted side effects...
2018-01-16In general the player assumes that it won't receive out of order video.Carl Hetherington
This clearly can happen with separate L/R sources. A pass in L might emit two frames which means the arrivals can't possibly be in order. This commit fixes this by introducing a Shuffler which all alternate-3D sources send their video to. The Shuffler re-orders things before they arrive at the player. It also fixes the code which inserts video frames before one that arrives after a gap. This didn't cope with 3D right before. The audio code solves a similar (perhaps the same?) problem with the AudioMerger; perhaps we should have a similar thing for video and make the player emit complete 3D frames. Should help with #976.
