'Perspective' and 'Orthographic' work great if you know what the parameters were to generate the exact object position, but what if you don't know them? That is where 'Corner Pin' comes in! With it you can specify the exact location of every corner down to the micro-pixel, instead of fiddling with parameters.
Fixes#565
As people appear to be far too willing to mess with settings they have absolutely no reason to mess with, removing these seems like the best option. Both of these can still be set if you know where to look, and aren't actually required for operation at all.
Prevents some scale factors from simply not rendering anything at all, resulting in weird scene layouts. While this may incur a higher performance penalty, it does fix the issue with enough accuracy to be deployed into production.
As none of the known Upscaling algorithms handle Alpha, we need to manually restore and interpolate it properly. While this technically reduces visual quality slightly, the chances of this being noticed are slim to none considering that Upscaling is already a questionable solution to quality. Linear was picked here as it produces the best overall result for scaling, keeping gradients mostly in one piece. Mostly.
Fixes#646
As the Alpha channel is completely ignored and possibly destroyed by denoising algorithms, we should restore the Alpha channel manually. Linear interpolation was chosen here as it will behave like Point if the size matches, and properly interpolate if the size doesn't match.
Fixes: #646
The previous name was too strict on what could be put into the effect, and would result in additional clutter in the Filter menu when we eventually decide to support other Upscaling methods than Super-Resolution networks.
As not all encoders need all functions, classes inheriting from this should not need to implement all of them as no-ops. Instead the header should take care of this, which reduces duplicated empty code paths.
As vargs may be modified by some functions, we should not reuse it and instead create a copy of it. This fixes a segfault on logging calls happening with GCC, and potentially may fix other compilers and platforms as well.
While the previous method worked, it matches no other implementation including a reference implementation. The new implementation almost perfectly matches the reference implementation and uses oversampling to achieve the goal. This has the downside of limiting the blur size to just 64, but it is necessary in order to achieve correct results.
Fixes#573
The CUDA library is always available as a singleton, so it does not make sense for it to be passed in. Instead we can simply grab it from the singleton and use it as it is, which makes the code easier to maintain and automates certain code.
This reduces the total amount of links Supporters can submit to just one instead of two. Additionally by removing the buttons and making the entry itself clickable, the UI can show more entries at once and allow users to easily make the connection between the entry and the link it opens when clicked.
The 'obs-ffmpeg-mux.c' file specifies different color parameters than StreamFX does. This causes re-muxing to go haywire, and editors that trust these tags suddenly spew out bad colors for BT.601 and sRGB.
Reverts #478
Qt defaults to give every QAction a TextHeuristicRole, which means that certain key words will cause Qt to change how the QAction behaves. We do not want this, so we explicitly assign it to have NoRole instead.
Fixes#323
Instead of adding ourselves as the last entry which seems to confuse the MacOS Qt implementation, we instead insert ourselves before the Help menu. This should hopefully prevent the StreamFX menu from overriding the OBS About entry.
Fixes#323
Grouping properties by what they do improves the user experience as the user does not have to guess at what belongs to which part of the effect. Additionally toggleable groups automatically disable all child elements, so the user is not confused by them still being active.
While the long descriptions were useful, keeping the updated and translated is pretty much impossible. Technology moves fast and not everyone that translates the project knows a lot about technology.
Therefore the long descriptions have now been replaced with a button that opens the wiki page for the feature instead. This should drastically reduce the number of help cases, and improve the translation coverage at the same time.
Both Rec. 601 and sRGB looked extremely wrong before, resulting in weird or warped colors. Since it is very difficult to find up to date and accurate information on standards, we should simply go for what has the most widespread support.
There is hardly any reason for us to recalculate everything all the time. LUTs can cache the work once, and then re-use it every time necessary, drastically reducing the impact of Color Grading by almost 60% (on some GPUs even more). Additionally this fixes the negative gamma issue, which plagued the filter for a while.
In the future, once PR 4199 (https://github.com/obsproject/obs-studio/pull/4199) has been merged, we can cut away one intermediate rendering step currently required to make the effect work. Hopefully this will be with the 27.x release of OBS Studio.
For simple image and video editing, LUTs (Look-Up Tables) are vastly superior to running the entire editing operation on each pixel - especially if all the processing can be done inside a single shader.
Due to the post-processing requirements for our LUTs, we are limited to 8 bits per channel - though clever use of the unused Alpha channel may result in additional space. For our purposes however, this is definitely enough.
A complete redesign of the component and dependency system is necessary in order to support additional platforms, such as MacOS and other Linux platforms. Additionally it results in a much cleaner code base, which is less confusing overall.
Eventually it might be necessary to push components of StreamFX into their own CMake projects, as it is getting kind of complex now. Especially with the push for a proper plugin manager, things get dicey for big plugins like StreamFX.
Ignoring the data parameter during initialization results in duplication and some third party plugins not working as expected, so it's better to not ignore it.
Fixes#315
