MP4Box problems with AC3 using command line

[mrloofer]

Calling all MP4Box experts!

Ok, so I'm attempting to join track #1 (video) from an MP4 file along with an AC3 file using the following syntax:

MP4Box.exe -add "c:\temp\file.mp4#1" -add file.ac3 outputfile.mp4

Note that this is the exact syntax that Yamb gave me in the log.

This is what I get on the output:

IsoMedia import - track ID 1 - Video (size 720 x 400)
Unknown input file type
Unknown input file type
Saving to c:\temp\outputfile.mp4: 0.500 secs Interleaving

The resulting file is then corrupt. Thing is if I use Yamb to do exactly the same thing it works fine, which I don't understand since Yamb is giving me the same MP4Box command syntax in the log!

Any ideas?

Cheers.

I guess you have the ac3 in same folder as mp4box? Or else must you add the folder like "c:\temp\file.ac3" .

Yep, the fiile.ac3 is in the same folder as mp4box.exe.

I've the same problem with a little difference:

I've an mp4 video file without any audio tracks and i want to put once. I try do do:

C:\Programmi\YAMB>MP4Box.exe -add "C:\Mp4\audio.ac3" "C:\Mp4\Out.mp4"
Unknown input file type (Feature Not Supported)
Error importing C:\Mp4\audio.ac3: Feature Not Supported

C:\Programmi\YAMB>

Anyone can help me ?

you should convert AC3 File to AAC, can do with ac3to and nero aac codec, when you convert ac3 file to aac mp4box work.!!!
