It would be possible to adjust the Quartz Composition through (a) wise thinking with maths or (b) blind guessing and luck tweaking variables. The current quartz composition in my git repo is only made for CamTwist and oriented for 720p not 1080p. *Quartz Custom Composition is the remaining step not complete. It is theoretically possible to experiment with the HDMI output of the Ricoh Theta S > Cable (Mini HDMI Output to Standard HDMI) > Capture Device (Blackmagic UltraStudio Mini HDMI Input to DisplayPort) > Quartz Custom Composition* > Quartz Syphon Plugin Output > OBS Syphon Receiver > RTMP > Streaming Service Theta-S camera: Product | RICOH THETA S.Another attempt using opencv instead of quartz:.Paul Bourke - Converting a fisheye image into a panoramic or perspective projection.Ideally in QC during dev one could use video input patch to use as reference for modifying settings, but it is not consistent with behavior when ran inside of camtwist.For testing / developing in QC, you’ll need to unhook the “Image (Required)” patch and use instead the image patch “image-example of 720p theta-s stream”.Change input image source to theta s on USB or HDMI input live stream, or use sample image from this git project’s root dir.Open theta-fish2sphere.qtz file in quartz composer.Download quartz composer from Apple’s developer site by searching for “Graphics Tools for Xcode”.Make sure to press enter after you enter new values. Step 3: Modify settings if you’d like, not sure it’ll make much of a difference yet.Step 2: Choose filter theta-fish2sphere.Step 1: View > Main Window, Double click “Webcam” and choose RICOH THETA S.Add theta-fish2sphere.qtz and theta-crop.qtz to Applications > CamTwist > Effects.Download camtwist, install to applications.Example of desired output (this is post-processed by theta-s software, but not available for live streaming):.Sample input file (raw dual fisheye from theta-s):.Theta-fish2sphere.qtz - this “routes” camtwist through Paul Bourke’s custom quartz patch project (see references modified version added : theta-fish2sphere_K.qtz with reference images to play with. Web front-end needs equirectangular image, see this example:.
