Change how video timing is done.

2024-01-28T01:01:56Z

This commit changes the approach with video timing. Previously, we would (more-or-less) try to use every video frame from the content in the output, hoping that they come at a constant frame rate. This is not always the case, however. Here we preserve the PTS of video frames, and then when one arrives we output whatever DCP video frames we can (at the regular DCP frame rate). Hopefully this will solve a range of sync problems, but it could also introduce new ones.

Fix handling of empty font IDs and default DCP fonts (#2721) (part of #2722).

2024-01-15T09:21:59Z

Previously we used an empty font ID as the default for when a subtitle has no Font, but in #2721 we saw a DCP with an empty font ID which raised an assertion (because we'd already added our default font with the empty ID). Here we try to fix this (and also make the default font correctly be that from the first ).

Fix possible deference of invalid iterator (if _reel == _reels.end()).

Fix DCP content font ID allocation to cope with DCPs that have multiple fonts

2023-10-15T07:10:18Z

with the same name in the same reel (#2600). Previously we had this id_for_font_in_reel() which would give an ID of N_font-ID. This means we got duplicate font IDs. Here we replace that method with FontAllocator, which gives an ID of N_font-ID for the first font and M_font-ID, where M is a number higher than the highest reel index. The idea is to support the required new IDs without breaking exisiting projects. There is some documentation of how it works in doc/design/fonts
