i used this command to extract the dav file
test@test-VirtualBox:~$ ./hikpack -t k41 -i digicap.dav -o contents
Magic : 484b5753
hdr_crc : 00001d1a (OK)
lang_id : 00000001
date_hex: 20150315
devclass: 00000043
File: cramfs.img, CRC OK
WARN: missing new_20.bin trailer file
Extra tail at the end of dav, 29082624 bytes, maybe firmware id?
------------------------------------------------
The Problem is i don't know which type of firmware i have. i just tried k41 and know it works. i can decrypt the tar.lzma files.
i use this command:
test@test-VirtualBox:~$ ./hikpack -t k41 -d webs.tar.lzma -o decrypted/webs.tar.lzma
by the way: can i use firmware from hikvision to update this OEM DVR?
Because i have a new product type and there is no firmware update available and i cant activate SSH on the DVR.
My main intention is to change the logo which is shown if no camrea is connected
