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.
Cuts down on a lot of duplicate code between
TimelineWidget/ViewerWidget/CurveWidget/NodeParamView
and TimelinePanel/ViewerPanel/CurvePanel/ParamPanel since they all use similar
time functions.
When dragging a value in the UI, we use a "single frame update" because we want
to prioritize the currently visible frame to give visual feedback as soon as
possible. Previously, we generated a single frame InvalidateCache() signal
from the widgets themselves, but this had the major downside of not necessarily
emitting the time that the viewer was actually showing (due to either node time
transformations or times differing between the effects panels and the viewer
panels). Now, we send a different signal that viewers can handle themselves to
update the time that they're currently showing. This means the fast updating
will work no matter how many viewers are connected at whatever time each viewer
is set to.
Previews don't need to be rendered full resolution, particularly since the
preview is hardly ever 1:1 size of the sequence. The functionality to render
at lower resolutions already existed, but there was no UI for it. This commit
implements UI to set the resolution divider on the viewer.
Implementation isn't perfect yet, viewer/renderer doesn't update yet when
the preference is changed so a sequence needs to be re-opened for the change to
take effect.
The ViewerGLWidget would receive raw GLuint textures while most of Olive uses
an OpenGLTexture C++ wrapper. Unfortunately this would lead to the C++ wrapper
getting destroyed since its instance wasn't kept in the ViewerGLWidget. This
meant by the time the ViewerGLWidget would re-draw, the texture would have
already been destroyed leading to some black frames. This is now fixed.
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.
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.
Updating values rapidly would cause strange jitters as a
byproduct of the viewer trying to update from the renderer while
it was still working. Rather than the viewer trying to access the
the renderer, we now send textures in the initial update signal
to keep everything synchronized.
I was looking for a way to update the length value automatically with signals
and slots (rather than just checking every time the viewer time changes). This
should do the trick.
Previously, the viewer could be set up with a custom PCM file to test playback
and scrubbing. Now these functions are connected to the audio renderer to
work within the render system.
The previous iteration was fairly OpenGL-heavy. It's now been separated into
a base class that is OpenGL independent and a derived class that is
OpenGL-based. Over time this should allow for portability away from OpenGL
if necessary.
