MeGUI mutex troubles!

[hackaro70]

Hi there,

I'm a newbie and, following your instructions I was almost able to convert a full HD stream in MP4 (H.264) format. Here is what I did:


decrypt the stream files (.m2ts, MPEG2 coded) on my hard disk

demute the stream files with DGIndex and got the D2V and the .demuxed files.


I use the D2V file with Avisynth creator to output the .avs batch script that I used with MeGUI


I launched MeGUI with x.264 Blue-ray profile and got an .mp4 file 1080p without the sound as expected.


then I used HdBrStreamExtractor to extract the AC3 sound track (in my language) the chapters file and the subtitles file (.sub format)


I converted the AC3 sound file in ACC Multichannel-HQ 256 Kbs profile (NERO codec) with MeGUI


and till here everything went fine. Then the troubles:

I tried a muxing job with MeGUI using MP4 Mutex and giving as input:

video: the moviefile.mp4
audio: the accfile.m4a
subtitle: the .sub file
chapter: .txt chapter file

1st of all the MeGUI return me an error about the .sub file telling me that's a wrong format ... I didn't understand what it means! :confused:

2nd, I excluded the subtitles from the process and I launched the MP4 mutex (here I understood that it's necessary to "join" an video h.264 compliant with ACC sound file to have a compliant iso mp4 file. Correct me if wrong) that returned me always the same error:

and at this point I really don't know what to do. My OS is Vista 64 Ultimate SP1 and I have updated MeGUI to the lastest stable version. Any hints? what am I doing wrong!? :confused:

Thanks in advance for all your replies and sorry for my bad english.

Have a nice day! ;)

how big(mb) is the video file only ?

ciao! (sono italiano anche io!)

the video file is around 4GB ...

Vobsub can't be put in mp4. I mean, you can probably do it with ffmpeg, but it isn't spec-compliant.

So what should I do to have selectable (you choose the option to see them or not) subtitles in an .MP4 !? :confused:

TIA ::)

but there is memory error.. so it's no due to vobsub...

but there is memory error.. so it's now due to vobsub...

Yeah, I don't have any ideas about the second problem because I'm a total noob.

Hackaro70 - Use Subrip or another program of your choice to use optical character recognition to convert Vobsub format (idx/sub) to Subrip format (SRT). When MeGUI's mp4 muxer is called, it will automatically convert SRT to mpeg-4 timed text (TTXT) and put those in the new mp4 file, where they will be selectable.

Hi Inspector.Gadget,

thanks very much for the hints, I will follow your procedure and let you know about it. Thanks again. :)

Buzzqw,

Have you ever experienced the same "memory error" limit with MP4BOX? ... If it's so how can I split the audio and video files and then how can I join them once converted to the final MP4? :)

or is there another muxer, different from MP4BOX, that doesn't suffer from memory limitation!? :)

[buzzqw]

MKVmerge has proven to be rock solid

if i would have to guess: your M:\ drive is formated as fat32?

[hackaro70]

no, NTFS , whY?

[buzzqw]

on fat32 no files can be bigger than 4gb

another test:
try muxing without audio, just video
mp4box bombs again ?

well ... no, it didn't crash in that case! :sly:

But I have to admit that it was very near under the 4GB limit. The only video file, in that case, was 3.9GB, while adding the ACC audio it becomes 4,1GB ... so I guess MP4BOX has the project file size limit to 4,0GB :(

that or the mingw environment of the builder (kurtnoise) needs to be patched with largefile support patch...

btw, it's "MUXER" or "MULTIPLEXER" not mutex...
