Implements a manual and automatic update checker with support for both release and testing update channels, allowing users to stay as up to date as possible. It is fully compliant with privacy regulations around the world, as it stays completely silent and inactive until the user gives the Ok to connect to GitHub for the latest releases.
Adds colored and inverted colored variations for Luma Burn, enabling some more fancy transitions with it. All variations with color support smooth fading, and allow choosing any possible color for the transition.
* #307 Fix MSVC exclusive strcmp crash in FFmpeg Encoders.
* #310 Add shadertoy effect.
* #311 Move template files to custom directory.
* #312 Hide encoders that the current system does not support.
* #313 Enable FFmpeg Encoders on Linux.
Removes the NVENC entry on systems without an NVIDIA GPU by checking if the library for it can be loaded. If it can't be loaded, it's likely that the user does not have a system with NVENC capabilities - and guaranteed that they can't use the encoder as FFmpeg relies on these libraries.
Adds a utility class and functions to load libraries and symbols from libraries somewhat safely. Libraries are immediately unloaded when the last reference to them is lost, so the shared_ptr should be stored if the library is actually needed.
Ubuntu 20.04 has officially replaced 19.10 as the latest version, and is stable enough that people can move to it. The script doesn't change much for that. However we do remove the needless extra builds here and revert to the system installed clang version, which thanks to other pull requests now works fine. For Ubuntu 18.04 that is clang-8, while for Ubuntu 20.04 it is clang-9.
Using '-Wpedantic' on any GCC warnings enables a lot of annoying warnings that don't actually warn about anything. Some of the warnings seem to exist purely for maintaining a certain code style, and have no actual effect on the program itself. Since there is no way to selectively disable warnings like on MSVC, removing it is the easiest choice.
Changes applied:
* Moved utility files to /util/.
* Removed unused #includes.
* Removed unused ::ffmpeg::tools function.
* Removed unused variables.
* Fixed missing parentheses in the version macro.
* Fixed missing override on virtual function overrides and removed unnecessary virtual keyword from them.
* Disabled additional warning for ATL headers on MSVC only.
* Replaced direct printf parameters with their macro equivalent.
* Replaced C-style casts with C++-style casts.
* Applied clang-format again after an earlier change to the CMake file broke the integration for it.
The levels 5.2 and above were added in a newer FFmpeg version than OBS Studio is shipping with. Ideally we'd take these options directly from FFmpeg, but that is for a future commit.
Fixes the issue where "high444p" shows as "high", and "high" shows as "main", caused by the internal option mapping never being correct across version changes. Instead of keeping our own copy of things that has to be adjusted for each FFmpeg version, it's easier to just use the FFmpeg values and names.
* Changes the encoder name to 'streamfx-{name}' from 'streamfx--{name}' as the latter is a typo, but adds a proxy to still support the latter in bad configurations.
* Some of the warning messages have been improved in order to better support end-users, and support for the new encoder error messages has been added.
* Adds support for the is_hw argument instead of blindly relying on obs_encoder_get_caps() which actually returns the wrong values due to rerouting.
* Fixed handler-less encoders showing up in the UI outside of debug builds.
Due to an oversight in the code, the fallback code would simply fail to work as the encoder was always the zero-copy version. This resulted in weird crashes and encoders not working that used to work before.
Fixes#295
