This likely isn't necessary, but was one of the steps made trying to debug
MSVC compilation. Considering the previous iteration was from 2012 and this
one is from 2019, it may have other improvements.
A slider can now hold a float value and display it in the UI converted to
either a percentage or a decibel (still returning a linear float value
programmatically for the rest of the code).
Earlier, footage that was not the same frame rate as the sequence had the chance
of their length value falling between a frame. This doesn't really help anything
with video since a frame is a discrete point in time, and only led to confusion
while navigating the timeline.
Splitting commands would run CopyInputs after set_length. Since length is now
a parameter (aka a NodeInput) the former would override the latter breaking the
implementation. This commit fixes that.
Transitions are nodes but have a few parameters that are programmatic and always
required. This lets people write external code for transitions as well.
OCIO config was set on a per-project basis, but we were using a singleton for
the ColorManager that would break if more than one project was ever open.
Now the ColorManager belongs to the Project and is always accessed through the
Project.
An earlier commit implementing media in and out parameters was primarily for
this addition. A simple control dialog for the clip's speed presentation
reimplemented from the old codebase.
This commit adds the background functionality of the render cache invalidating
whenever a footage's color space is changed. This includes when the project's
configuration is changed as well.
The viewer had the color management backend in place already, but the frontend
was non-functional. This commit implements most if not all color management
functionality.
Uniform values cannot be set if the shader is not bound, and calling Blit would
release the shader making subsequent iteration count updates not work. This
commit makes sure the shader is bound before trying to do so.
Ultimately it would be nice if nodes could configure this themselves, but
CLAMP_TO_BORDER behavior can be written manually into the shader if that
behavior is desired, whereas CLAMP_TO_EDGE cannot.
Implemented the ability to load a node externally. This XML data could also
eventually be copy/pasted between instances of Olive alongside XML data for
other nodes and their connections to allow copying entire node trees.
These could be reimplemented almost wholesale, however the code has been
cleaned up and documented and the XML metadata has been updated to support
international translations.
