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
Adds a BeforeInstall step to the InnoSetup installer which uses the msvc-redist-helper tool to automatically check for the necessary DLLs and install the required redistributable if some are found to be missing.
Additionally slightly modernized the installer with a design that isn't from the 90s, and paves the way for preventing updating StreamFX while OBS Studio is still running.
* "Quality" Minimum/Maximum is actually QP Minimum/Maximum
* Bitrate Limits is now just Limits
* Buffer Size and Quality Target have been moved into "Limits".
