Due to an oversight, incoming footage frames were NOT converted to the
working pixel format (usually half or float). For most frames, this meant the
OCIO conversion would occur on frames while they were still in their source
format (usually either RGB8 or RGB16). This leads to rounding error
inaccuracies, but even worse GLSL will clamp integer textures to 1.0 potentially
losing a lot of data.
While later nodes would correctly convert to the appropriate format, by then it
would be too late. This commit corrects this issue, converting the frames to
float during the OCIO shader pass.
This framebuffer was an early approach to the pixel sampler that never got
used, but was still getting created/destroyed unnecessarily. This has now
been removed.
Rather than the cumbersome and small "node connectors" (introduced a while ago
when nodes had more than one output), this is a more streamlined system of
connecting nodes (hold Ctrl and drag to connect)
While developing, we used a function that only exists in OpenImageIO 2.1.x+.
Fortunately however, it seems to have simply existed with a different name in
earlier versions so we can maintain compatibility with 1.6+.
Implements an extra widget to display images on a separate monitor. Both
viewers have separate display color controls since different monitors may
conform to different standards/transforms.
There's no real reason not to use float for audio. It's light on system
resources (compared to everything else we're doing at least) and the code
becomes simpler when we can assume all audio will be -1 to 1 rather than 0 to
255 or -32768 to 32767.
The only thing we might want to do one day is move up to SAMPLE_FMT_DBL, but
this should only take some mild refactoring and all our assumptions (i.e. -1 to
1 range, etc.) can remain the same.
While we implement an audio cache "truncate" function when the sequence length
changes, the render functions also have the ability to extend it. This is fine,
but if truncation happened while workers were caching, it could truncate and
then extend beyond the length of the sequence. This commit changes the worker
extend function to only extend as much as the length, therefore not undoing the
truncation.
