Thanks.

There's no file libpng12.so.0 on Debian sid. I think it's a little bit old because in the system I can find the package libpng16-16 which has the the following files:

/usr/lib/x86_64-linux-gnu/libpng16.so.16.25.0
/usr/lib/x86_64-linux-gnu/libpng16.so.16

ERROR : Kernel header magic is not valid !

I tried to unpack a logo.bin from a Gretel A7 (based on the MT6580), but mtkimg fails with:

ERROR : Logo header type is not valid !

The problem is the case of the string "LOGO" at offset 0x08, the program expects an uppercase string, where I have a lowercase one.
After fixing that, there is another problem with the decoding of the raw data. It seems that mtkimg expects an RGB565 formats (16 bit), but in my case I have images in bgra format (32 bit).

I successfully decoded the binary files (after z-decompressing) with:

ffmpeg -y -vcodec rawvideo -f rawvideo -pix_fmt bgra -s 720x1280 -i file.bin -f image2 -vcodec png file.png

Hello rom1nux,
I am using your mtkimg tool for AMAZON Fire TV with MTK-8173 chipset.*
I am facing some problem during repacking. Can you help.

I did the unpack, using the following command:
#*./mtkimg unpack -m
It created 3 files:
-rw-rw-r-- 1 pintu pintu *349 Jul 31 18:15 image.cfg
-rw-rw-r-- 1 pintu pintu *14M Jul 31 18:15 kernel.img.mtk
-rw-rw-r-- 1 pintu pintu 761K Jul 31 18:15 ramdisk.cpio.gz.mtk

After that, I just tried to repack the same image again.
#*./mtkimg repack newboot.img -n -k kernel.img.mtk -r ramdisk.cpio.gz.mtk
MTKIMG V0.44(linux64) by rom1nux
Repacking image to 'newboot.img'...
ERROR : Configuration file 'image.cfg' is not a valid 'ROOTFS' or 'RECOVERY' image descriptor !

But it gives the above error.
Can you help me, what is the problem. And how to fix it.

If possible, CC me in this mail id: [email protected]*

Thanks,
