Mp4Box Video Concatenation

[Kreez]

Hiya,

How do we concatenate [append] 3 or more MP4 files to a single MP4 using MP4box.

the -cat and -add options miss out atleast one or more videos and the audio is totally out of sync.

anyone to help me out there !!

is there a good guide/manual for mp4box.

Bye.

Try mp4creator from MPEG4IPTools. It's a lesser known alternative to mp4box. It might work better.

mp4creator cant cat

for being able to cat two streams, the streams need to use exactly the same encoding options

extract the streams to raw .264 with mp4box, run h264_parse from mpeg4ip over it and check whether the sps and pps parts are identical for all streams. if not, post the differences here

Hi,

It Works now.

The constraint using MP4Box is that all input videos must have same encoding options.
