mj2_target::add_video_track

Returns a pointer to an internal video track resource, to which compressed data and rendering attributes can be written. Each call to this function creates a new video track, with a distinct track index. You may determine the track index using mj2_video_target::get_track_idx.

At a minimum you will need to configure the colour space information (see mj2_video_target::access_colour) and the frame-to-frame period (see mj2_video_target::set_frame_period) for the new video track, before writing compressed frames (or fields), with the aid of the mj2_video_target::open_image and mj2_video_target::close_image functions.
