Absolute time at which the frame is supposed to be displayed. This is in
the same unit and base as the time returned by mpv_get_time_us(). For
frames that are redrawn, or if vsync locked video timing is used (see
"video-sync" option), then this can be 0. The "video-timing-offset"
option determines how much "headroom" the render thread gets (but a high
enough frame rate can reduce it anyway). mpv_render_context_render() will
normally block until the time is elapsed, unless you pass it
MPV_RENDER_PARAM_BLOCK_FOR_TARGET_TIME = 0.
