Summary | 0000047: New Subtitle Interface: madVR CPU queue causes delay updating subtitles after scaling | ||||
Description | Using a high CPU queue in madVR causes a noticeable delay before subtitle bitmaps are updated after scaling. | ||||
Steps To Reproduce | *Set CPU Queue to 32. *Resize video with a subtitle line visible. *Very long delay updating subtitle bitmaps for the new resolution. *Set CPU Queue to 4. *Resize video with a subtitle line visible. *Very short delay updating subtitle bitmaps for the new resolution. | ||||
Additional Information | madshi comment (04/22/2013): Probably madVR should automatically request newly rendered subtitles for all frames in the queue (which were not presented yet) when you scale the madVR window. I don't think I already do that right now. | ||||

I've now modifies this to update the subtitles at once, but only when in paused mode. When in normal playback mode, I'm not doing that, because it would require a rerendering of all frames. So basically every small scaling change could potentially result in frame drops. I think it's not too much of a problem if the subtitles are a bit blurry or aliased for a few frames. I think it's more important to avoid frame drops. |
