I'm not entirely sure how the iPod Video bootloader works. You probably
don't really need any of the code in the binary, but the partition
contents need to be structured correctly for the second stage bootloader
to find the rockbox bootloader. While I did craft some empty "container"
firmware partitions for the iPod Classic a couple of years back, I'm not
sure of anyone ever did that for the Video (which has quite a few
differences). It's probably not worth the hassle - just put on the Apple
binary and patch the Rockbox bootloader into that. (Or if you really
want to, dig into the image format and remove other parts that you don't
need.)

You don't need iTunes though. On the iPod Video, I think you can just
grab the file from Apple's servers and dd it onto the firmware partition
on the iPod's disk, as documented in the wiki. (On the Classic they went
through the effort to hide that partition and make it only writable
through vendor-specific SCSI commands, but we have a tool to fake that,
and I don't think it's needed for the Video anyway.)
