Kitchen function broken in Monster Hunter Freedom Unite for ALL git builds starting from v0.7.6-389-gd952f74

[solarmystic]

UPDATE:-

After much testing and head on the wall banging I've finally narrowed down git version that caused this issue to be replicated 100% of the time without fail.

It's this massive merge pull commit that merged Atrac3 support in sceAtrac via FFMPEG into the main PPSSPP code that's the source of this problem d952f74

All git versions starting from v0.7.6-389-gd952f74 (which is the first one to have it) exhibit the problem and it is replicable 100% of the time.

The lastest git revision that does not have this specific kitchen issue after repeated and persistent testing (10 times each git revision using the same methodology outlined in problem replication section) has been narrowed down to v0.7.6-387-g9922756, which funnily enough is the last one before any form of FFMPEG support was merged into the PPSSPP code. #1662

I now have a much, much greater appreciation for the testers and devs of this fine emulator.

EDIT:- I also discovered that holding turbo prior to eating in the kitchen also causes the issue in otherwise working builds.

ORIGINAL POST:-

As per my post in the ppsspp forums:-

There is an issue with the game in the latest git version v0.7.6-483-gc4529ef. This is older issue actually but doesn't happen consistently like in the latest build.

The last working build tested without this issue at all for MHFU was the official 0.7.6 release by Henrik on the main website.

Description of the problem:-

The game gets stuck/unresponsive after you eat a Felyne prepared meal at the kitchen. Without fail. No matter the ingredient combination.

You see the felyne chefs just clapping their hands over and over again, you can't move and the game refuses to respond to any button presses. Holding down turbo does nothing.

Problem Replication:-

The steps to replicate the problem are as follows:-

1. Load your savegame. Preferably one where you've just completed a quest.
2. Head to your home, and then the kitchen.
3. Eat a meal prepared by your felyne chefs.
4. Watch game get stuck in a loop after you recieve the meal bonuses.

I've posted a video on youtube that demonstrates the issue better than words. Observe the ending of the meal in particular. The cats kept on clapping in a loop that wouldn't end.

Knowing which exact git build this started happening in would help significantly. To confirm, you're saying it never happened in 0.7.6, or that it happened but not with 100% reproducibility?

This is almost certainly the same as all the other Monster Hunter hang problems with some queue overflowing, what does the log look like when this happens?

It almost never happens in the official 0.7.6 release on the main ppsspp webpage. I've just tested the same savegame to elicit the problem:-

In 0.7.6 official release the kitchen problem doesn't occur

In the git build (v0.7.6-483-gc4529ef) I posted above it can be reproduced with a 100% certainty. Without fail.

The main difference between both builds is that I can replicate the issue (kitchen endless loop) consistently in 0.7.6-483, while in the official 0.7.6 build, I cannot.

Here's the log file for your perusal (in 7z format):-

Indeed another "Queue Full!" problem. I wonder what queue that is. A msgpipe?

Scheduling changes since 0.7.6 may have affected it.

@hrydgard

Here's another log file for your perusal when the problem does not rear it's ugly head, and the kitchen segment runs smoothly. Perhaps you can find out the difference between them when the issue occurs and when it doesn't. I'm not quite proficient in these matters.

@solarmystic , can you test the build from @oioiff to see if you can still reproduce this issue ?

https://docs.google.com/file/d/0B1ftGc2t9-dZVUZsUUZIYmFtRTQ/edit?usp=sharing

[solarmystic]

Yes I have raven. The same issue is exhibited on not just his latest build, but all of his builds. I went as far back as his first build (dated 15th March 2013).

https://docs.google.com/file/d/0B1ftGc2t9-dZcGpBT0NCb3AwT3c/edit?pli=1

Which makes me suspect the implementation of FFMPEG even more.

[dbz400]

Can you try this build ? rename it from jpg to zip , extract and run it with those dll lib from oioitff build

[solarmystic]

Well what do you know.... the build you posted solved the issue, twice out of ten attempts.

I placed it next to the dll libs from the oioitff build (The avcodec, afvormat, avutil, swresample-0, and swscale dlls) and tried to replicate the issue. I couldn't reproduce the issue the first time. The second time issue came back. Third time it resolved itself. And the next seven times it came back.

Did you figure out what was at fault?

[dbz400]

Seems to me that it is random . This build basically disable the ffmpeg code to be functional however looks like may be other code not related to ffmpeg causing problem .

[solarmystic]

Okay, but the fact that it does work some of the time instead of failing 100% like in the other tested builds implies that ffmpeg could be at fault. As I mentioned earlier it was the builds on orphis post the ffmpeg merge (any build after 0.7.6-389) that all have the problem all the time.

Last working build that does not display the kitchen loop issue at all and works properly 100% is still ppsspp-v0.7.6-387-g9922756-windows-x86.

Thanks for being patient with me.

[solarmystic]

Closing this page for now as the issue seems to have been resolved as of 0.7.6-804. Kitchen function now works as intended. Will reopen if it returns.

[unknownbrackets]

Really? That's weird. I'd be very interested to know which revision actually fixed it.

This combined merge https://github.com/hrydgard/ppsspp/commit/1b3079142bb58bc57d05a6720ecf8193f636e185 of your audio blocking functions into the master is the one that seems to have done the trick. Git revision v0.7.6-685-g1b30791 is the first build not to exhibit the kitchen issue with repeated and persistent testing.

Thanks again @unknownbrackets

[unknownbrackets]

Hurray. I thought it might fix something but I was disappointed when none of my games seemed to care. Glad it helped, thanks for checking.
