RPCS3 freezes on startup #280

Closed thegamingrestoration closed 4 years ago

thegamingrestoration commented 4 years ago

Using the latest version of RPCS3 (0.0.7-9004-6944e180 Alpha) https://rpcs3.net/download

Using the OpenGL renderer, the LLVM Recompiler and the OpenAL audio backend, the game starts but doesn't advance past frame 0. I tried using different options, but the only one that lets the game start is "Uncontrolled Time". Here's the output from gdb:

RPCS3 is using Qt as its frontend, so it is likely it won't work on the current version (Hotline Miami is using Qt and I couldn't make it to work). They don't seem to offer another frontend.

Also, it would greatly help libTAS if we would be able to only open the game window. I'm seing a --no-gui command-line option, but it gives me the following error: QWidget: Must construct a QApplication before a QWidget. Did you manage to launch the game window only?

thegamingrestoration commented 4 years ago

Yes, I managed to open the emulator with the following command: /home/x/.config/rpcs3/dev_hdd0/game/ARTPS3001/USRDIR/EBOOT.BIN --no-gui And now the emulator freezes in the first frame (1 instead of 0), without showing any errors:

If there is a freeze, check uncontrolled time, debug - print categories - time get and see what function(s) pop up. Next enable those functions in runtime - timetracking

Ok, I read the Time Get calls, enabled time(), clock_gettime() and SDL_GetTicks(), and ran the emulator again (without Uncontrolled Time). Now I can see the emulator's FPS counter, but everything freezes after the third frame. The gdp output is slightly different but it still doesn't show up any errors:

Is it advancing time in any way on the libtas window? Sometimes the frame counter freezes but its still advancing time.

Another thing you can try is debug - keep first thread. This same thing happened with midnight club 2 wine

Good news! The emulator works after enabling "Keep main first thread", even without the --nogui parameter.

The problem is that.. it works only when I move the mouse. Every time I stop moving it, both the emulator and frame counter freeze, same thing with the sound.

Here's a small demonstration: https://gfycat.com/dopeyhalfdormouse

Also, the keyboard works ingame, but it doesn't register any input on libTAS, and the mouse stays at 0:0 all the time.

Maybe the Qt libraries are interfering with the recording? LibTAS seems to recognize all the necessary components:

Video support: unknown (OpenGL 4.3 Core profile)
Audio support: yes (OpenAL)
Keyboard support: default (xevents)
Mouse support: default (xevents)
Joystick support: unknown

(I can't use the gdb debugger to get more info, it crashes the emulator)

Have you checked runtime - asynchronous - xevent?

Well, its nice to see it runs through libtas.

Have you tested encodes yet? If that works fine, we can at least use it for segmented runs with frame advance and slow downs to make it easier.

There are still problems with threading, but you should be able to run with "Runtime > Time Tracking > clock_gettime()" and "Runtime > Debug > Time tracking all threads > clock_gettime()" with commit 90a2e39d946741fbad3a0034b812f7558e073875. The latter option can cause desyncs.

thegamingrestoration commented 4 years ago

Awesome! It works now! It's a bit unstable (probably the emulator's fault, the --no-gui parameter is not very well implemented), and some games run much slower; but otherwise the input,sound and video encoding work perfectly.

The only remaining issue is that libTAS is unable to play movie recordings. Whenever I try to play an ltm file I can see my keyboard inputs onscreen, but they don't register in the emulator.

InfamousKnight commented 4 years ago

Yeah, it runs slow because libtas is using a software renderer. If you turn that off, it will run at its native speed, but save states will likely crash. So the fact that frame advance works, means that its technically a tas.

thegamingrestoration commented 4 years ago

I had the software rendering setting disabled the whole time. libTAS is definitely slowing down the emulator, and whenever I click on Stop, libTAS suddenly disconnects from the emulator, and the emulator runs fast again. I think there's something wrong with the way libTAS handles the wait calls, but that's probably what @clementgallet meant with problems with threading.

clementgallet commented 4 years ago

Keyboard inputs should work after commit 0a7744cbd411aa6d4bae0e5742a3dad38436524d

Yeah, mesa OpenGL software rendering does not support OpenGL 4.3, which is required by RPCS3. As a consequence, it is likely we won't be able to use libTAS savestates.

thegamingrestoration commented 4 years ago

Thank you so much, recordings now work properly :) And I'm sure this will also fix other games & emulators that rely on xcb events.
