The everlasting OSD

[RandyAdamsTN]

It is possible to change the pause feature to display the OSD only for about 5 seconds, then go away. Alot of times we like to pause the show to read any words or fast action. The OSD staying up all the time gets in the way. I know there is a setting for minimal OSD in the config program, but thats not what I am looking for, I want to see the time line, but if it stays paused for a few seconds, go away.


Thanks for reading.

I cant change the OSD in any way while the video is paused with VMR, including hiding it. This is just the way VMR works.

That doesn't sound very pragmatic. I don't know very much if anything about DirectX, but I find it hard to believe that when video is paused, you can't..

Copy the current buffer to a secondary off-screen buffer (like you would if you are going to overlay something).

Draw that buffer to the screen.

Tear down the primary buffers and whatever else is neccesary.

Start it all back up again with no OSD.

Swap the primary and secondary buffers.

Take my word for it, its true. When you're playing video using the Video Mixing Renderer, the overlay bitmap can only be updated while the stream is running. This limitation does not exist when using the Overlay renderer.

If you're playing video with frame accurate seeking (AVI) you can seek back to the current frame to force it to update the OSD. With MPEG2, which is primarily what GB-PVR uses, there is no frame accurate seeking, so if try this approach results in funny stutters as the video moves up to half a second.

Its not a huge problem, and most people dont even notice. The only place its obvious to me, is when you pause playback of an in-progress recording, and the recording length shown in the OSD doesnt update. When you use Overlay instead of VMR, then it does update.
