[Debburn-devel] read named pipes

[Tom Deblauwe]

Hello,

I have a question about writing files to an iso image.

I want to write an iso image, with the following structure for example:
/cam1.mp4
/cam2.mp4
/cam3.mp4

I have a lot of small files on my harddisk, which I need to read, strip 
some things of of them, and then append the remaining data of that file 
to for example "cam1.mp4".
I first thought that I could make a directory with named pipes, and then 
write that directory to an iso image using genisoimage. But it just 
writes the named pipes literally to the disk, it doesn't ask data from 
those pipes.

I tested this:
mkdir burn
cd burn
mkfifo test.txt
cd ..
echo "hello world" > burn/test.txt &
genisoimage -J -r -o test.iso burn/

This gave me an iso with test.txt that was 0 bytes, and of file type 
"pipe". So it didn't read that echo. How can I do this, or is there 
another way?

Thanks a lot,
Best regards,
Tom,
