My feel sceMpegInitAu has something wrong
edit:I just find mpegAvcAu,mpegAtracAu declare in global variable in JPCSP source.

Bump, still hasn't been fixed yet on the latest svn.

Not related, but can we request for "skip mpeg/video playback" feature as a temporary workaround for games like these that hangs/crashes when trying to playback the video?

as @daniel229 metion I/O Timeing method:Host work
This is secound stage,

I/O Timeing method:Fast: (bad)
Media engine log and sceio log:
https://gist.github.com/sum2012/9b59fb1da89f436faf4b

I/O Timeing method:Host (good)
Mediia engine log and sceio log:
https://gist.github.com/sum2012/2862d49c26587b7e8c12

Hope @unknownbrackets have idea to fix it.

[unknownbrackets]

In sceIo.cpp, under __IoRead, there are these lines:

    // Low estimate, may be improved later from the ReadFile result.
    us = size / 100;
    if (us < 100) {
        us = 100;
    }

If you use "Fast" and change size / 100 to size / 50 does it help? Also, if you make it size / 100 + 3000 does it help?

[sum2012]

Both change help this game,but not Innocent Life #2830

[unknownbrackets]

Do any other values higher than 50 work? Like 80 or 90? Just want to get a sense of how sensitive it is.

-[Unknown]

[sum2012]

Last work value 62 ,first bad value 63

What is the correct fix , increase delay in sceio or scempeg ?
if (id == PSP_STDIN) {
DEBUG_LOG(SCEIO, "sceIoRead STDIN");
result = 0; //stdin
return true;
}
Do we need to add a check for PSP_STDOUT and PSP_STDERR ?

[Terra854]

Is this issue fixed yet? I can't get my Android PPSSPP to play all the cutscenes for this game as of 1.2.2

[sum2012]

@Terra854
You need this option to fix.

[daniel229]

Fixed in #8867

[unknownbrackets]

Ah, sweet. So it was a seek rescheduling issue, probably... wait, it was the mpeg change. Well, that's good too.... I guess it was about how much it read before starting the video?

[sum2012]
