v.buffertap Output the frames in a v.buffers object as a stream. Output the frames in a v.buffers object as a stream. v.buffertap accesses the frames stored in a v.buffers object of the same name. You can have multiple v.buffertaps accessing one v.buffers. You have several ways of playing back the frames: playing, looping, reversing_looping, and manual control. You can tell v.buffertap to interpolate between frames when the speed is slow, or you have manually specified a floating point frame number. You can set in and out points in v.buffertap to allow you to play and loop subsections of the buffers. If the in point is larger than the out point, the clip plays backwards from in to out.
