[Mp4-tech] Re: cmp format

hi asaf!
oh yes that could be the failure,...but I think I also tried (during my
diploma work this spring) to make a yuv with premiere. Maybe you can trie
out this: to take an avi and make a yuv out of it with premiere, virtual dub
or some other videoedit-programm...
maybe this works?!
regards,
karin

Hi Karin,
Thank you very much, it was a lot of help.
I think you didn't succeed in the first method because the output of avi2raw
is still MPEG-4  coded (video only), and the necessary input for encoder60
is a "Real" raw file - one which is in YUV format.
Now the only question is how do I take a movie and convert it into a YUV or
RGB format. (the output would probably be huge in size).
Thanks again,
Asaf.

hello!
You can use MPEG4IP to create a *.cmp file. I've created several *cmp files
with this programm but they couldn't be played in any MPEG-4 player.. I
don't know if this is because the players do not support this file format or
because I created the file in the wrong way...
but you can try it:
At “DeXT stuff”, http://peque.metropoliglobal.com/dext/index.html you can
download the MPEG4IP package. After downloading you can follow the
instruction from "encoding.htm".
sort summary of the instructions:
1) convert your video file into a raw video (avi2raw.exe)
2) then you have to write a .par file (an example see attachment)
3) convert the *.par file with the encoder60.exe to a *.cmp file
But I have had much more success with the video formats from ENST
(http://www.comelec.enst.fr/~dufourd/mpeg-4/)file formate: .nhnt,.media and
.info (you can create them with the mp4tool from ENST. But they can only be
played with the ENST Osmo4 Player!
Generaly I didn't really succeed in creating video files that could be
played with more than one (different) MPEG-4 players.
good luck!
regards,
karin

Hello,
Hello,
I saw your address in the M4IF technotes newsgroup regarding to cmp format
of MPEG-4.
Can you help me to find a tool that can demux an AVI or MPEG file encoded
with MPEG-4 into a video .cmp stream?
How can I create such a file format with a commercial software, or transform
another format into cmp file?
Regards,
Asaf Jazcilevich
