Implements the following:
- Sequences have pixel aspect ratios that work in tandem with footage PARs
to render footage correctly. Viewer and export also acknowledge PARs
- Sequences can have interlacing settings. This doesn't do anything yet,
eventually the renderer will need to interlace/deinterlace/reinterlace
appropriately in order to conform all the footage to the sequence. Export
acknowledges interlacing, but this only affects metadata, not the image.
We had support for detecting aspect ratios and respecting them in the
render, but this allows people to not only see the aspect ratio in use,
but also override it with their own.
There were a lot of issues that arose from trying to make GUI changes
from another thread (even though we ran those functions in the right
thread). Now we store layout information until the end of the load and
make the changes then. This works much better from both a business logic
and user experience perspective.
Also prevents multiple sequences from taking focus during load and
starting a render job.
Backslashes are the normal directory delimiter for Windows so Windows users
will likely be more comfortable with this. Also prevents issues where a
filename may appear twice in the "open recent" list for both slash
directions.
Removed proxy task and replaced with a true honest-to-god pre-cache for
footage. This footage is pre-cached to a sequence and therefore 100% ready
for use in it once the task is done.
Made various changes and fixes to the task system:
- Tasks are built around QtConcurrent rather than QThread. Reduces
code complexity significantly.
- Task error reporting is now streamlined in both TaskManager and
TaskDialog.
- Moved ProjectImport/Save/LoadManager to the app/task folder
Turned the two-step PCM transcode into one step and simplified/removed much of
the unnecessary infrastructure that supported it. This makes the code cleaner
and generally improves the code paths.
This required various changes to various parts of the infrastructure (mostly
using paths to finding the "root project" of any given object throughout).
Now theoretically infinite projects can be opened and accounted for at any
given time.
Implemented the ability to copy/paste blocks/clips in the timeline. This did
require some large scale changes and reworking of the copy/paste system
introduced a few commits ago, but should be largely functional now.
Updates drag mime data to include a variable determining which streams are
enabled and which ones aren't (a binary qint64 where the 0s are disabled
and the 1s are enabled) rather than relying solely on the stream->enabled
values which can't be modified as part of the drag process.
Should address any XML parsing issues and allows for simpler, more maintainable
code. Should also address a crash that could occur when pasting nodes that had
inputs that weren't copied.
