In the Photos and Camera applications, watching slo-mo video allows the user to set the time for the ramps, which affect the video playback speed.
When importing a video into my application through the UIImagePickerController, these ramps seem to be included in the asset that I receive. However, Im writing a custom image selection controller and ramps are no longer automatically included in the asset. I suppose I need to wrap this asset in AVMutableComposition and then add speed ramps, but I cannot find the ramp metadata anywhere.
Is accelerated metadata available anywhere?
