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.
As OBS Studio locks some mutexes in a different order depending on what actions are being done, using modified_properties for GPU work causes things to freeze in place. Instead have users manually click the refresh button when they changed files in order to prevent this freeze from happening.
Fixes: #118
Ever wished you had a professional camera operator to highlight and follow the action, ensuring the audience never misses a beat? Thanks to NVIDIA, you can now do this at home for free! The new NVIDIA AR SDK unlocks augmented reality features, including motion tracking for faces.
This allows me to provide you with an automated zoom and cropping solution for your video camera to transform your streams into a slick, polished broadcast, where you’ll always be the star of the show. Don’t forget - everything is customizable so the possibilities are endless. You can even recreate that Futurama squinting meme if you wanted to (with some scripting)!
The filter requires compatible Nvidia RTX hardware and the Nvidia AR SDK Runtime to be installed ahead of time. This filter is considered "stable" and shouldn't change much from version to version.
Adds support for specifying Minimum Bitrate directly in the UI instead of requiring custom settings to do so. Additionally Adaptive I/B-Frames are now only shown if Look-Ahead is a value greater than 0 frames.
Quality Minimum can also now be left at a default value of -1, the Quality group is no longer toggleable and Quality Target moved into the group. Settings options on the context is now searching children too (if there are any).
Finally, some C++17 formatting was done.
Fixes#101
This drastically improves stability and prevents all exceptions from leaking into libobs C code, which prevents crashes and unexpected freezes from exception handlers further down the stack.
Additionally minor work was done to further improve the quality and user experience for the filter.
Caching the output of a source is only necessary for really expensive to render sources, so it is disabled by default now. Thanks to that, most Source Mirrors are now "free" instead of requiring two context switches and a texture, while those really expensive can be manually set to cache.
The scaling mode is also set to disabled instead of point when rescaling is off to further improve performance. The previous method would incorrectly cause an extra texture to be used.
Additionally we now have support for debug markers for graphics debugging, allowing us to exactly tell apart improvements in rendering cost for this source.
