Several things are accomplished in this commit, including:
- Use OIIO instead of our own functions for pixel format conversions
(cleaner code/less for us to maintain)
- Fold all PixelService functions into the PixelFormat class
(cleaner code)
- Moved OpenGL pixel definitions to OpenGL classes and out of the
global classes.
- Add support for RGB buffers as well as RGBA (optimization)
In the previous commit, we added a dialog to give users options when dropping
footage on a sequence-less timeline panel. However some users will have a
preferred behavior that they'd want every time without having to go through
the messagebox, so we add a "don't ask again" option that stores the setting
in the application config.
If there was anything that 0.1.x taught me, it was that a substantial number of
users did not understand that a new sequence was being made by dropping footage
onto an empty timeline and wouldn't know what to do if they wanted parameters
that differed from the footage they dragged in. This dialog makes the operation
clear and gives users an option to set the parameters on drop for convenience.
Improves viewer appearance and performance. Rather than using a timer roughly
set to the sequence's frame rate to update the viewer, the viewer synchronizes
itself to the display's refresh rate resulting in much smoother playback.
An earlier commit addressed faulty TaskViewItem ordering by changing
insertWidget to addWidget. Turns out this was the wrong strategy since the
insert was used to get widgets above the stretch. The correct strategy is
using insert(count()-1) instead of insert(0)
functions
Indexing is a lengthy process and had a high chance of getting RenderWorkers
stuck doing it rather than being responsive to cache requests. This commit
introduces a system where workers never index media, but instead signal that
media is not ready to their RenderBackends which ensure that the media gets
indexed and re-queues the affected frames when those indexes are ready.
Nouveau has poor compatibility with Olive (and most other graphically intensive
applications). For user benefit, we throw a warning messagebox if we detect the
user is using Nouveau.
context
More intuitive code flow and allows the user to undock the viewer (which
forcibly destroys and recreates the context) and the viewer will handle
creation of the new texture in said new context.
"toggled"
Only signal a change if the user made one. Toggled would be signalled even when
we set it programmatically (e.g. by simply creating the checkbox widget and
setting its state) causing unnecessary re-caches of the sequence.
