Heh... it is merged. Okay... Just tried building a static build and at3plus worked well. No crashes.
Ghhh, what have they done with gui? Most of the buttons are quite difficult to access. I will post the required changes for osx build when I get them ready.

if you can upload your xcode project and what changes you mae to the atrac3plus decoder i can make it a dynamic library for ios so it can be used like the other builds right out of the box

I already suggest a solution to use the latest version of the .dll :

1°) Delete your .dll from your PPSSPP directory.
2°) Launch PPSSPP.
3°) It will show you some explanations about the .dll.
4°) Click on the "Download and install" button.
5°) Click on the "Back" button.
6°) Now you're using the latest version of the .dll ! Wink

If PPSSPP don't ask you if you want to download the .dll, launch PPSSPP and click on the "Settings" button, then the "Audio" button and finally the "Download Atrac3+ plugin" button Wink

@vnctdj: the PPSSPP always freeze and unresponsive when I go to settings and download the plugins... so how to fix this??

That's strange... I don't know why Huh

Apparently someone have had the same problem, look at this.

Change it to stat? I can hardly imagine atrac3 files larger that 4 GBs... That worked for me on OSX at least.

So, I was testing Persona 1. The videos play fine, but performance is really bad. I get an average of 52 FPS, so sound and video slow down.

This is really weird because on the MUCH slower JPCSP those videos play without a glitch or performance issue.

On JPCSP playing a Persona video just takes 15% or so of my CPU power. On PPSSPP the same video maxes one core and it can't keep a smooth playback. Which is really weird since JPCSP has usually an horrid performance compared to PPSSPP.

The rest would be all fine, if it wasn't for a texture bug in Persona that makes it basically unplayable (since those textures are used frequently in combat, for example):
https://github.com/hrydgard/ppsspp/issues/1793
P.S.
This is also doing something very strange with the memory. As the video starts the memory starts increasing slowly as the video plays. I've seen it climbing up to more than 2Gb! If this is a memory leak it's the largest I've ever seen Wink

Fadeout: did you max out your texture scaling/filtering options or something? What you describe does not happen for me at all. I get 900 vps with fast forward, and it never uses more than 90 MB of RAM.

Of course, there is the ugly black boxes bug, yes...

Edit: oops, but I don't have this atrac3+ plugin thing installed, which is probably why you posted in this thread, n/m.

Nope. I've just verified that with atrac3+ off there are no changes at all: the video still plays at 52 FPS and I get memory usage going up steadily during playback till it fills the whole physical memory.

So I know for sure that both the performance and memory issues are 100% due to video playback/sceMpeg.

Tested again at 1x with options disabled, no scaling. No changes. Still same performance and memory problem. This with 1248 build.
