Question: if I was to try to make a multicam editor as a c++ plugin for reaper, what's the best way to grab the video frames from the tracks? a video processor eel2 can make a grid layout in the video preview window using input_track() but that's not clickable. I guess I need uess I need something like GetAudioAccessorSasomething like GetAudioAccessorSamples but for video.. would it using WDL_VideoDecode? thanks Justin!
