Can MP4Box does everything YAMB could?

[tigerb]

It says "YAMB - Yet Another Mp4Box GUI for windows", so....I'm assuming YAMB is using MP4Box and theoretically MP4Box could do everything YAMB could (not to mention the latest MP4Box is dated 2011 whereas the last YAMB was dated in 2009).

I've a FLV file in H264 which I need to Demux, so I extracted the file with FLVExtract.exe and the end result is T1.264 and here is the strange part:

1) I drop the file (T1.264) into YAMB (2.1.0.0 beta 2 June 29, 2009) using the "Editing" > "Join", the file got processed perfectly and now even Windows Media Player could play the file.

2) If I'm to use MP4Box with " mp4box.exe -cat "P:\T1.264" "P:\New.mp4", MP4Box crashed!

1) What gives? or my -cat command is not right? -cat = join, right?

2) How does one use MP4Box (what command/s) to FIX a problematic/non indexed/no headers/file which is playing too fast .264 file?

Thanks.

-cat is concatenate or append (as in append sequentially file A + file B)

yamb is just a GUI; mp4box can do anything yamb can, but the versions of mp4box might be different. Yamb will have one bundled with it, probably an older version. It might be better or worse might offer different functions

Yamb is has a box where you can enter the value for FPS, but you use FPS to enter the FPS for mp4box

mp4box -add input.264:fps=25 -new output.mp4

Thanks poisondeathray, you are of great help.

I have the attitude of never give up till I find the solution/s, and upon installing the latest MP4Box MP4Box-0.4.6-rev2735 (previously I was using MP4Box-0.4.6_x64-rev2698, couldn't find the x64 version of 2735, that's why not updated for so long)...and got the missing MSVCP100 dll something error message and found out this 2735 needs vcredist_x86.exe.

Bravo, rev2735 processed my T1.264 without any problem (but I got this strange looking screen with tons of not implemented pic timing part..., is this normal or supposed to be there), but anyway....the end result is perfect again without having to go thru YAMB or MKVtoolnix, just like the good old 2 steps: 1) Use FLVExtract.exe and 2) Use Mp4Box, I'm happy now, lol.
