[Help] Access Violation Encoded In MEGUI
Well...To be brief, I have recently built a rig for encoding. The CPU is AMD threadripper with 32GB of ram and nvidia GeForce GTX 1080i. Anyway, I have installed avisynth+ with MT capable. Before that, I had avisynth 2.6 MT, the latest version. Unfortunately, it didn't work with HD videos and always gave me the out of memory errors and also was much slower compared to avisynth+. And the avisynth 2.6 MT only worked on DVD rip but worked pretty well except HD videos. So I switched to avisynth+, it is amazingly fast esp with the one that has MT built-in. The first few encodes were fine took about 17 mins for 45 mins of video for DVD rip. Then afterwards, it acted up. It always gave me access violation error half way of the encode and then crashed. In other word, it never completed the encoding. At first I thought it was a MEGUI problem, and I am still not sure. But I have tried a few different version of MEGUI, but still crashed and generated access violation halfway during the encoding.
I have also done the ram test - No problem. The rams are working fine. I also checked the CPU, the temperature was below 70 C. Graphic card no problem either. Attached with this message or post is the log of the plugins or scripts that I used. Hope somebody could help please. Last edited by jinkazuya; 11th October 2017 at 16:23. |

Attachments can take a few days to get approved . I'd recommend posting that to a 3rd party site, or even a free file host
If the crash occurs exactly at the same place each time, then maybe there is a problem with the source at that point. Or when you say "half way" did you mean approximately ? |

Yes approximately not really at the same point every time it occurred. Let says the video that megui determine's to be 750mb as the finished product of the encode. Inbetween 0 to 750mb, the error would occurs randomly and anytime during the encoding process. Sometimes it stopped at 350mb and sometimes it stopped at 500mb etc. But the same script and videos encoded with my old rig pc installed with ultimate window 7 with 8 threads enabled, it encoded pretty smoothly.

I have to correct what I said previously. With avisynth+ installed on my old rig window 7 ultimate, testing on the same video, it also crashed every once and then. Does it mean avisynth+ is not stable enough or are some of the filters or plug-ins or even scripts not 100% compatible with avisynth+.
After I used avisynth+, I like it better than I do the regular avisynth. It is a lot faster and use's less cpu cores. |

Avisynth+ MT is more commonly used now, and there aren't very many reports of issues like yours
It could be any number of things . It could be your hardware, or one of your plugins, or a specific issue with that x264 build. If I had to guess, one of those plugins have threading issues. Check your plugins, for example Quote:
So go through each of your plugins used in that script and make sure they are correct and updated If you still have problems, use a methodical process of elimination eg. start with using the script with different encoder like xvid in vdub, or just avsmeter . If that works, then problem is either with that x264 build or megui If it's the same crash then start removing filters one by one and repeat |
