It's not easy to tell whether the OSD/subs are empty, or if something is drawn. In general you have to use osd_draw() with a custom callback. If nothing is visible, the callback is never invoked. (The actual reason why this is so "hard" is the implementation of osd_libass.c, which doesn't allow separating rendering and drawing of OSD elements, because all OSD elements share the same ASS_Renderer.) To simplify avoiding copies, make osd_draw_on_image() instead of the caller use mp_image_make_writeable(). Introduce osd_draw_on_image_p(), which works like osd_draw_on_image(), but gets the new image allocation from an image pool. This is supposed to be an optimization, because it reduces the frequency of large allocations/deallocations for image data. The result of this is that the frequency of copies needed in conjunction with vf_sub, screenshots, and vo_lavc (encoding) should be reduced. vf_sub now always does true pass-through if no subs are shown. Drop the pts check from vf_sub. This didn't make much sense. |
