Any way to dump and replace video frames?

Video Any way to dump and replace video frames?
Hi! I've seen around the forum that it used to be possible to dump video frames, but that it was changed so that videos would be avoided. I've also seen that at some point, there used to be an option you could change in the texture.ini for the game to allow you to dump video frames (video = true) but I tested it (only with Persona 3 Portable) and it doesn't seem to work anymore. Sooo, as the title says, is there any way to replace video frames nowadays?

I'm working on a Persona 3 Portable HD Texture Pack, and I would like to try and upscale the opening video.

If the option is not available anymore, where and how can I request it?

Here? ...github.com/hrydgard/ppsspp/pull/8715 (Initial texture replacement support)

RE: Any way to dump and replace video frames?
Frames of some videos can be dumped, but it might not work as you think it would as it still just dumps textures which might not have any actual video frame graphics;p. You can try by adding "video = true" under options in your textures.ini.
Replacing such textures back would not work anyway at least not smoothly since PNG format can't be directly uploaded to GPU as it's image and not a texture and has to be converted first which has a small delay that get's noticeable with higher res.

Better "video replacement" might be problematic as explained by [Unknown] in here.

You can also look into "video aware" shaders, basically another uniform called "u_video" can be used to detect whenever video is playing or not and apply different effect to video than the rest of the game smoothing it out better or in more artistic way than all the other graphics / in-game, but this will also be problematic in some games as "video might be playing" as part of some tiny 2D effect in-game applying the video effect to everything;].

Ohh, that's a shame Sad I tried to add that line for the intro of Persona 3 Portable before posting here and it didn't dump anything, so I guess it's just not going to be possible :/ And yeah, I guess it just wouldn't work very smoothly anyways :/ But who knows, maybe some day we'll be able to use dds textures, which would solve the lag Big Grin Right? XD

Thanks for the answer!
