MeGUI - x264/XviD/lavc/Snow encoder with MP4/MKV/AVI output & audio

[Taddeusz]

MeGUI in combination with Avisynth and the CoreAVC decoder don't seem to play well together. I can get previews and everything just fine. When it comes time to transcode the video if I click on the progress window MeGUI stops responding. Once x264 is finished MeGUI comes back to life, at least on shorter videos. This doesn't seem to happen with any other dx filter. Just with CoreAVC. Any ideas?

They all worked just fine on my computer. I was using CoreAVC, MeGUI and Avisynth all just fine on both windows xp with sp2 and with sp3.

Although that was a few months ago when I was still using DirectShowSource for both h.264 and vc1 sources.

My recommendations are to make sure CoreAVC, MeGUI and Avisynth are all updated to newest available.

If that doesn't work I really don't recommend using DirectShowSource anyways. You should be indexing the h264 file with DGAVCDec from neuron2.net. If the source is VC1 though, you have to 1) have an nvidia video card that support CUDA and 2) you have to be a contributer on the website neuron2.net to be able to use the VC1 decoder/indexing programs. At least the h264 one is free.

Hope that helps

DSS2 from Haali's splitter package is also a nice alternative when partnered with FFDShow-Tryouts. I use this all the time, as it's frame accurate and multi-threaded, since DGAVCDec is not multi-threaded.

[alc0re]

Oh...I didn't know there was another solution that was frame accurate....

Decodes VC1 also?


I'm not that worried about the decoder being multi-threaded since as far as I know, the decoding is hardly ever the bottleneck (as least with me dealing mostly with HD content.)

I can't convert AAC to MP3. The error says "DirectShowSource: Could not open as video or audio." I am using latest version. I think I have done this before with no problem.

[Inspector.Gadget]

mencius, you need an AAC decoder. Install latest ffdshow-tryouts (if you haven't already) and make sure AAC decoding is enabled in the audio config.

[mencius]

Thanks Inspector.Gadget. I already had ffdshow installed. I tried installing the latest version and checked everything (avisynth serving and plugins, etc) and set it to decode aac. But still doesn't work in Megui.

[Inspector.Gadget]

Do you have an MP4 splitter installed? (File may not be "raw" AAC).

[mencius]

Yes I have Haali Media Splitter installed. I reinstalled it but still no go.

if your avs doesnt play in a directshow media player, megui cant encode it.
fix your directshow filter chain until the avs script plays back in a DS media player.

[mencius]

Okay thanks, it works now. I installed "AAC parser filter for DirectShow".

Otherwise, I have the other settings all at default (eg, postprocessing, resize, sharpen, levels, overlay, etc. are all OFF/disabled.)

Also, on the Output & RGB Conversion tabs, should I make any changes or just leave those at default?

Many thanks

I posted the above question a while back, but didn't see any response, so I figured I'd try asking again.

Could someone who has some good experience or knowledge please recommend the appropriate settings to use for FFDShow's Deblocking option; and for Output Colorspace when used as a decoder with DirectShowSource? I'm assuming that using the wrong settings for those options would affect the quality of the encode to some extent?

Many thanks!

ask in the appropriate place.

Well, I know there are several different places where I could have asked, but really, what's inappropriate about here? Is there noone here who uses MeGUI as a frontend with ffdshow/directshowsource and have any advice to offer? There's all sorts of talk here about different ways to get the source video (and audio, as _you_ recently contributed to) into the encode process. I don't see anything inappropriate in asking for some advice from people who use a specific tool regularly.

And while I'm at it, if you were going to take the time to post a reply, if you thought I asked in the wrong place, could you not have maybe suggested what the appropriate place would be, rather than just post a snide, useless comment. Seriously, that was quite rude Sharktooth.

@therealjoeblow

I can't answer the question you have about the settings to use (see my pm that I sent you)

But, I would suggest not using DirectShowSource for re-encoding your existing h.264 encodes. Head over to neuron2.net. Go to the section titled Mine, and download DGAVCDec AVC/H.264 Decoder and Frame Server. Trying using that to index your raw h264 file and then using that tool to decode frame accurate video to avisynth. Works just like DGMPGDec. Its a better solution than using DirectShowSource.

Leave everything as default (everything unchecked), if you change the settings, the output file will not match the input file (unless that's what you want to do). If you have any filters activated in ffdshow, they will pass through to the encode if you are using DirectShowSource() and ffdshow as the decoder (usually unwanted)

If you need to do a colorspace conversion, you can specify that in your script. Most sources (DVD, blu-ray) will be YV12 anyway, so you don't need to do anything. Avoid unecessary colorspace conversions, because they are lossy.

Hi i wasnt sure where to post this but this seemed to most logical place at the moment. if its in the wrong place i do apologise. And please can someone notify me if it gets moved or such.

The problem i am posting about is a virus being downloaded with the MeGui updates. It is of the malware type and today is not the first time i found it. I found this previously but thought myself to have landed unlcuky. So after removing the previous completely and taking all neccisary precautions i re-installed MeGui from a fresh DL of the latest build and did the usual update to aquire the rest of the tools to go with the application. Then ran a virus check once again to be sure (AdAware) Againthis has come up with a virri is the DL'd files. And quite a serious one at that.

Here is the details -

C:\Program Files\megui\tools\eac3to\HookSurcode.dll
C:\Program Files\megui\update_cache\eac3to-316.zip:HookSurcode.dll

Win32BackDoor.Hupigon
also known as
Win32BackDoor.Graybird

As you can imagine i am finding this quite shocking as have used MeGui for quite some time and swear by the app.
If someone could please clear up whats happening here i would be most grateful. The virus is quite serious and i wish to continue using MeGui....

Thankyou for anyones time and look forward to reply's.

eac3to and its libraries do not contain viruses. That is a false positive. Check the eac3to thread for details.

[buzzqw]

just 2 words: "False Positive"

hooksurcode is a dll by eac3to use for commanding Surcode DTS Encoder.

It's safe software. You can check on eac3to thread. There are many antivirus that flag it as virus. BUT IS ALWAYS A FLASE POSITIVE.

you can report to your antivirus
