Indeed there's an object named VideoDecoder but it is not used with streamed media - why separate the two decoders it is basically replicated code using the external codec API.

What I don't understand is why video playback has to be controlled by gnash on frame granularity. It would be far better to treat the a/v decoder as a standalone entity with create, destroy, configure, play, pause, stop, query etc' methods. Configure methods can connect this decoder entity with the NetStream/DiskStream on the one side and with the renderer/GUI on the other. Of course clip and transform changes must be propagated to the video decoder (or more precisely to a video compositor entity). Frame based control should only be done if it is required - for instance I don't know the flash spec that well but if videos can be embedded in such a way that they need to be synced with the rest of the graphics to frame-accuracy (and not timestamp accuracy) current style sync is necessary. In any case a compositor entity could receive frames from GUI, videos etc' and do the sync according to the current scheme, scaling, filtering and format-converting as necessary for each input. This kind of a design lends itself much better for acceleration (be it multicore CPU/GPU or dedicated codec HW).
