Yeah, that looks goofy. That's very acute observation, BoardLord, congrats. It's a bug in DGIndexNV. I've fixed it and will release a new version soon with MP4 container support. Sorry for the inconvenience and thanks for helping me to improve DGDecNV.

I've used MeGUI with a screen capture and PCM audio. The muxed output MP4 has no audio. Aften and ffmpeg will create a stereo AC3 file at 128k and 22050 which match the original PCM source. I tried to mux that audio with the MeGUI-created video using mkvmerge. End result is a muxed file but the audio does not play because it is unrecognized. MeGUI's muxer drops the audio file, writing only the video portion.

Is there a required audio sampling rate? Do I need to resample? If so, is mono supported?

Here it is. There is a statement about a decode error with the audio file but the entire source was encoded to ac3 by aften and will play. This was a webcast and there were a couple of drop outs. That shouldn't affect the structure of the source file, though.

Looks like your AVS - load VirtualDub frame server.ac3 file is not handled by MediaInfo...

Could you run this file into mediainfo GUI from the official website and paste the result here ?

Hey, no problem, glad that I could help Your exemplary support was one of the main reasons I bought DGIndexNV!

There's not much to paste. You are correct, MediaInfo doesn't properly recognize the file.

Code:
Complete name                            : E:\AVS - load VirtualDub frame server.ac3
File size                                : 76.8 MiB

Thanks for the kind words. There's a release candidate with a fix for your issue here:

Ok...could you upload your ac3 file somewhere ? or a sample from your original stream...

AC3 don't support 22050 samplerate, but Aften convert a wav file with this samplerate to 44100 and create a valid AC3 file that is not recognized by MediaInfo.

Encoding for multiple bit rates!

Hello,

I am using MeGUI to encode 6 multiple bit rate MP4 files to use them on adaptive streaming. I am creating 150k, 300k, 500k, 800k, 1200k and 1800k variants.

150k, 300k, 500k and 800k variants use the same resolution.

1200k and 1800k will use different resolution.

My current steps:

1. Get the source .VOB file from the DVD.

2. Create AVISynth script for 500k - First pass. This stats file is used as input for 150k, 300k, 500k and 800k second pass, so that I can get same key frame settings.

3. Create AVISynth script for 1200k - First pass. This stats file is used as input for 1200k and 1800k.

4. Encode Audio into 48k and 128k.

5. Mux Audio & Video.

Is there any easy way of doing the above steps automatically? Currently, after creating 500k first pass stas, I need to copy and create new files with the same names as 150k, 300k, 800k. Similarly for 1800k.

I tried with Windows Task Scheduler to copy the files automatically. But, had few issues (some times) while copying the stats files if the video duration is very small (500k second pass finishes fast and the 150k pass will be looking for 150k stats, which is not yet created by task scheduler).

Also, I created different X264 profiles to add the above bit rate encoding to the Queue manually.

Thank you for your time!

Thank YOU for the offers to help.

Here are the first 30 seconds of PCM exported from VirtualDub as a WAV.

A sample:
I tried ffmpeg to make the AC3 and had the same issue. So...what to do? Resample to 44100 then encode to AC3 with BeSweet?

update: BeSweet failed so I resampled to 44100 in VirtualDub and saved as a WAV then encoded with MeGUI and muxed. Final result works.

Perhaps MeGUI should be modified to only allow supported bitrates.

Hi,

Replace current MediaInfo library by the one available from this package. Choose the one for your platform (x86 or x64)...and retry an encoding. That should be ok now.

Haali installation?

Can someone please help me understand why the log is now warning that Haali Matroska Muxer and Haali DSS2 are not installed? I'm not aware of them ever being installed in the past, and I assume they're not required or they'd be included in the MeGUI updates. Would like to know if I can safely ignore the warning, or need to get them onboard. Thanks.

They are only required for people who prefer processing media formats not well supported by FFMS2 (like M2TS directly, instead of remuxing that to MKV first). Therefore it is just a "Warning", nothing which keeps you from continuing.

P.S.: Haali Matroska ... "Muxer"? Not "Splitter"?

Yes, it says "Haali Matroska Muxer". I initially though "Haali Media Splitter" too, which I don't have installed currently.

So my usual format of IFO/VOB's from DVD Decrypter is not affected by and/or wouldn't benefit from these missing components?

Ah, then it means dsmux as tool to convert e.g. TS to MKV.

No, they are "nice to have" for specific cases, but DVD Video can be processed with PGCDemux and DGMPGDec/FFMS2 only.

No, it is the splitter. Will be renamed in one of the next builds. Without the splitter some functions in FFMS or eac3to may not work - also DSS2 will not be supported.
It is not possible to add it to the updater as it must be installed.

I just installed Haali Media Splitter / Matroska Splitter from http://haali.su/mkv/ and MeGUI is no longer showing a warning for the 2 items in the log.

Does that sound correct Zathor?
