megui 0.3.0.2015 is crashing during encoding, tried 679 and 682 x264 builds

[hajj_3]

build 979 is crashing, i've sent the bug reports to MS if you can get them off them, just randomly crashes during encoding:( same happens with build 682 so think it might be a megui problem.

me too .

but use build 965 , no crash problem

i think maybe x264 problem

r979 works for me (xp pro 32-bit)

Check you CPU temps (e.g. coretemp), reset your overclocks, check your memory with memtest64+

My two PC also have this problem
NO overclock.

PC1 - Intel PD 935 with 2.5GB (vista SP1 64-bit)
PC2 - Intel C2Q 9300 with 6GB ram (vista SP1 64-bit)

do x264 have a fund set up to pay ms for crash logs? if not it might be worth posting on forums asking for donations, im sure coreavc and divx would pay for the money needed.

Okay, I can also add my confirmation, atleast for build 979. I have not yet updated to the new builds. But what was happening is that it was crashing on the exact same frame every time (17660). The crash log generated by Microsoft claimed x264 as the issue. I will update everything to the latest build and give it a try.


Edit: Bug also confirmed for 982. Same frame again. And I checked the source (a lossless encode of an anime episode) and that frame is one hundred percent fine. Along with the adjacent frames.

try with 983 (now in the auto-update). it it still crashes, contact the x264 dev reporting the possible bug.

1. Microsoft isn't going to do anything, and their bug reporting feature is utterly worthless; the data dumps contain nothing useful at all and might as well be /dev/random.

2. Yes, there's a confirmed bug in x264, but I've only found a few extremely rare cases that can trigger it. I'm waiting on akupenguin to wake up and explain to me why the current code was what it was before I change it, but he hasn't responded to me for almost half a day now, so I'm considering just pushing it in and ignoring complaints...

Edit: Screw it, committed. Thanks to b0bor for sending in the minimal test case necessary to find the bug.

I have another encode running right now, doing a lossless pass before x264 encoding, and it is setup to run with 983, so I will see if that one crashes.

It is interesting that you say it is rare, as yes, I had one encode run fine in my Queue, and then on the next encode, the crash occured. Both were anime episodes, however they were totally different series, meaning different animation styles and use of b-frames, if that is what is causing the crash (i don't know what the issue is, but it is good to hear that you do Dark Shikari).

This next encode is live action, so I will see if anything happens with it.

maybe you could build in a crash system into x264.exe so that if it crashes it can send a complete detailed crashlog to the x264 developers, quite alot of apps have these nowadays like flashfxp amongst many others.

Also, a backtrace is sometimes not possible unless you use --no-asm too (it was in this case).

still crashes with 683 build:(

still crashes with 683 build:(Bugfix was in 985, not 983... :rolleyes:

[hajj_3]

ahh, hope its added to megui auto-update soon and i'll try again.

thanks.

[Sharktooth]

done.

build 685 fixes the crashing:)

you can close this thread now.

Yep, I confirm. My encode worked perfectly!
