Render video. Requires that the OpenGL state is initialized.
The video will use the full provided framebuffer. Options like "panscan" are
applied to determine which part of the video should be visible and how the
video should be scaled. You can change these options at runtime by using the
mpv property API.
The renderer will reconfigure itself every time the output rectangle/size
is changed. (If you want to do animations, it might be better to do the
animation on a FBO instead.)
This function implicitly pulls a video frame from the internal queue and
renders it. If no new frame is available, the previous frame is redrawn.
The update callback set with mpv_opengl_cb_set_update_callback() notifies
you when a new frame was added.
@param fbo The framebuffer object to render on. Because the renderer might
manage multiple FBOs internally for the purpose of video
postprocessing, it will always bind and unbind FBOs itself. If
you want mpv to render on the main framebuffer, pass 0.
@param w Width of the framebuffer. This is either the video size if the fbo
parameter is 0, or the allocated size of the texture backing the
fbo. The renderer will always use the full size of the fbo.
@param h Height of the framebuffer. Same as with the w parameter, except
that this parameter can be negative. In this case, the video
frame will be rendered flipped.
@return 0
