How to concatenate possibly non compliant mp4?

[DiscError]

I bought a sanyo vpc-cg10 camcorder that produced mp4 files. I can play this file just fine.

But when I tried to concatenate several such files together I could not. As soon as I try to add a stream with mp4boxgui it says something to the effect of illegal or invalid file.

Using YAMB doesn't work either. The resulting file has the size of all the input file summed, but when played, only shows the first clip.

Could someone tell me how I can either make this file into a legal mp4 file or other means to concatenate them?

i have no problem with your sample:


mp4box -cat SANY0004.MP4 -cat SANY0004.MP4 -new final.mp4

mp4box -cat SANY0004.MP4 -cat SANY0004.MP4 -new final.mp4

You're right! Turns out I can join the file using command line. There must be something wrong with the guis.

Thanks!!
