(See ``<mpv/opengl_cb.h>``.) + Usually, ``opengl-cb`` renders frames asynchronously by client and this + can cause some frame drops. In order to provide a way to handle this + situation, ``opengl-cb`` has its own frame queue and calls update callback + more frequently if the queue is not empty regardless of existence of new frame. + Once the queue is filled, ``opengl-cb`` drops frames automatically. - This supports many of the suboptions the ``opengl`` VO has. Run + With default options, ``opengl-cb`` renders only the latest frame and drops + all frames handed over while waiting render function after update callback. + + ``frame-queue-size=<1..100>`` + The maximum count of frames which the frame queue can hold (default: 1) + + ``frame-drop-mode=<pop|clear>`` + Select the behavior when the frame queue is full. + + pop + Drop the oldest frame in the frame queue.
