The git history is required to determine the version number correctly, and without it the generated archives unfortunately lack that information making them look identical to earlier versions in log files.
By configuring and building 32-bit and 64-bit builds in parallel we can save massive amounts of time usually spent just waiting on other resources while the CPU is idle. On AppVeyor, this results in a roughly 50% lower build time, ensuring that builds can complete faster than before.
Artifacts have been reduced to only be created for tagged releases, which also reduces total build time. Additionally the notifications have been reduced to only happen when the build status changes, as there is no reason to notify about things that did not change the status.
Small performance optimization as this removes the extra texture render that would be done by libobs which we don't actually need as we already have a texture to render to for it.
Rendering happens with cached Geometry that is only updated when necessary, such as when the user changes settings. This optimization was necessary to reduce CPU and GPU usage as we can simply re-use the same geomtry instead of recalculating it.
However, the actual source size was never checked. That meant that when a source changed size through any means, the filter would not update the geomtry accordingly, and the result was a squished or stretched image.
With this, the source size is now checked each tick.
Fixes#48
The number of files in the source directory was a little bit much and just made file naming more complex than it had to be. Therefore all files were moved into subdirectories where it matters.
Filters now reside in source/filters/, Sources in source/sources/, OBS Wrappers in obs/, OBS GS Wrappers in obs/gs/, Transitions will reside in source/transitions, Graphics Helpers will be in gfx/.
MipGenerator.Strength was renamed to MipGenerator.Intensity, which better fits the actual intention of the property. Additionally all the mipmap generator options are now correctly named.
Gaussian blur used to have a hard edge which was caused by the filter width being wider than the actual sampling range, which is what is determined by the size option. In order to fix this, we have to figure out the proper filter width for a sampling range, so that we avoid any and all hard edges.
Additionally removes the old texture method entirely.
Fixes#44
Earlier versions tried using Trilinear as the Filter, but the correct name is Linear. With this the sampling is now set to be Linear instead of undetermined.
Additionally the logic for the displacement was adjusted and now no longer renders incorrectly when going from texel to texel. This was due to the unstable math being performed to retrieve the sign of the number, but the sign() command can do it without this math being required.
Source Mirror would incorrectly crash if an Audio only source was selected, as it expected a video frame to be present of any size. This fixes the problem by first testing if there is any video information to render and then just catching any exception that happens during rendering.
The normal OBS behavior is to cache files that are loaded from disk, however this is not the behavior we want at all, as it can miss file updates as it never checks the disk for an updated file.
So instead of relying on OBS, this implements the file reading and effect creation without the cache. If a cache is necessary, it would not be the job of this class.
This works around the incorrect shadow on the edge of the Signed Distance Field, but it does not get rid of it completely. Due to linear sampling it will still show at some point so a different solution has to be found in the future.
Colored shadows previously had an effect on the image color, but this is incorrect if the image is fully opaque. This fixes it by using premultiplied alpha mixing instead.
This allows increasing or decreasing the accuracy of the Signed Distance Field at runtime without requiring the initial source to be resized. Use case for this would be small text where the higher quality would only be noticable on the shadow and not the text itself.
Sources were rendering with a black border around them if they had a soft fade, which is due to how the shadow calculated the image sample. With the new shader code this is now fixed and the source looks like it should be. Additionally this removes the bug where enabling any shadow would cause only the texels to draw that were above the threshold.
Additionally this adds support for inverse gradients (min > max) and negative gradients for outer shadows instead of only positive gradients. This technically allows for cleaner shadows.
The nature of this Signed Distance Field based Filter is not to only draw shadows, but to also draw an outline or even glow around a source. Therefore the name "Inner/Outer Shadow (SDF)" does not fit well with the intent of the actual Filter.
Allows for enumerating any kind of source, as long as it has a name and is not private. As obs_enum_scenes is a 23.x and above function, this class should be used instead to remain backwards compatible.
