MP4Box concatenating in same video stream

[Alphait]

Hi,
I've already tried to contact with MP4Box developers but with no luck so far. So I've desided to post my question here as well.
I'm trying to concatenate several video clips in one using MP4Box with -cat option. In manual they say that if source videos match then MP4Box will concatenate video in existing video stream of result. But if source video has different parameters new video stream will be created. My goal is to create resulting movie with only one video stream without encoding. I'm searching for fast way to do that. So I want to compare source videos for myself to make a desision if it is possible to concatenate without encoding. But I don't know which parameters to compare.
Could anyone provide me with a full list of video parameters for comparing?
I know that there is source code of MP4Box available, but I don't understand C so it make no sense for me ((((
Thank's for any help, guys!

Personally I would analyze the videos with MediaInfo and compare Video Format, Video Resolution, Frame Rate, Level and Profile, ScanOrder, to figure out if the content can be appended,...

MP4Box -cat file1.mp4 -cat file2.mp4 output.mp4should work if the content of the two files is compatible,..
