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
* "Quality" Minimum/Maximum is actually QP Minimum/Maximum
* Bitrate Limits is now just Limits
* Buffer Size and Quality Target have been moved into "Limits".
Proxies allow for older configurations to work fine on newer versions, without having to manually adjust the scene collection to match the new ids at all. Thanks to the migration system we can freely support any number of old versions, as long as we write migration code.
Occasionally, mostly due to other sources rebuilding their UI, an out-of-order lock freeze can be observed with Source Mirror. This is unwanted, so we need to move the freezing logic into a place where freezing shouldn't happen.
Fixes#228
Actually fixes#61
Moves the menu for StreamFX to the primary menu, so that it is not hidden under tools. This makes it clearer to the user if their installation of StreamFX is working correctly, in addition to reducing the steps necessary to use the menu.
Also the 'About StreamFX' dialog now actually shows up for every update, as expected.
Adds support for enumerations, a different way of selecting how something should behave in a shader. Enumerations rely on a continuous list of values, and will automatically detect how many values there are in the enumeration. Only non-vector types are supported as enumeration entries, and array/vector parameters can have each member set to a different enumeration value.
Furthermore suffixes now are properly assigned, and 'bool' no longer causes shaders to stop rendering. Additionally by inlining some functions and using std::string_view we can achieve a slightly better performance than before.
Using std::string_view over std::string (and const std::string&) has the advantage that we skip potential temporary std::string objects that are immediately thrown away, thus slowing down the code. It can also be implicitly cast to std::string, which makes it compatible with existing code that uses std::string.
The high priority CUDA stream causes libOBS to be at a lower priority than the tracking, which is not what we want. Instead we want tracking to be incomplete in those cases, rather than slowing down encoding and other things.
Geometry updates are also now done once per frame instead of one per tracking update, which should improve the smoothness without affecting performance too much. Additionally all tracking info is now in the 0..1 range, which drastically simplifies some math - especially with texture coordinates.
To deal with tracking and updates being asynchronous, a very simple approximation of movement velocity has been added. This is mostly wrong, but it can bridge the gap where tracking updates are slower, as the values are all filtered anyway.
