Myy, Korean today
<Myy>
Yup !
<Myy>
I'm trying to understand why the mpp_test is getting no informations from the VPU
<Myy>
And yet, it does not display error messages like "Can't find the VPU" or "Unknown platform"
<stdint>
I could read a few difference Asian language but the Korean is excepted
<stdint>
Myy, it won't
<Myy>
it won't display error messages ? Or find the right VPU informations ? :)
<stdint>
the platform detecting method comes from me, it only use dts information and check a few device node
<Myy>
Oh
<Myy>
I guess that the best way to test it is to install MPP directly, use gstreamer and give it a shot then ?
<Myy>
Also, I'm unable to force MPP to avoid compiling static libraries. Even though I defined -DENABLE_STATIC=OFF -DENABLE_SHARED=ON
<stdint>
Myy, which branch?
<Myy>
The develop one
<Myy>
According to git branch
<stdint>
Myy, use the for_linux branch
<Myy>
Alright
<Myy>
Oooh, it compiled !
<Myy>
I'll try vpu_api_test then, with a simple MP4
<stdint>
Myy, rk3288?
<Myy>
Yup
<Myy>
MiQi board
<stdint>
I didn't add the supporting for MPEG-4 Part 10 for that soc
<stdint>
Myy, have a try on mpi_dec_test
<Myy>
Is H264 ok ?
<stdint>
the input file could be found here
<Myy>
Oh !
<stdint>
Myy, only vp8, jpeg, hevc, avc is supported at rk3288
<stdint>
the decoder
<Myy>
Alright
<stdint>
ok, I found I have not upload it
<Myy>
I'll try with Big Buck Bunny
<Myy>
WebM format will do then ? (VP8)
cyteen has quit [Remote host closed the connection]
<stdint>
Myy, it can't accept any video contents
<stdint>
you need raw bitstream
<Myy>
Ah, without the headers then
ganbold has quit [Quit: This computer has gone to sleep]
<Myy>
So I extracted the datastream, using mkvextract tracks "bigbuckbunny.vp8" --raw 1:video.vp8
<Myy>
And then using mpi_dec_test returned that : https://ghostbin.com/paste/dufc3 I'll try to see if I can run MPP directly on the Debian box this evening, see if I can get something with it.

Hi everyone, how to stop uboot (rockchip loader) to get uboot command prompt?
<beeble>
is bootdelay set to -1 ?
<hardik_>
no
<hardik_>
in parameter file i did set it to 10 but it's not stopping
<beeble>
ah you want to get the prompt. not the other way around. sorry for missunderstanding
<hardik_>
can i do it using command line parameter ?
<hardik_>
and what is recovery partition ?
<beeble>
sorry, i'm not familiar with the rockchip loader tool, never used it. but if you are using a mainline u-boot setting CONFIG_BOOTDELAY via menuconfig should be enough. to be sure you can set it to -1 that should always give you a prompt
<hardik_>
ok
<hardik_>
no source code for bootloader
<hardik_>
it's a close source
<hardik_>
i mean rockchip loader
<beeble>
what board/soc do you have. you may not need it anyway
<hardik_>
read only flag " ro " also not working with mtdparts
<beeble>
mainline u-boot seems to have spl/tpl support. but that my be not what you are looking for
<beeble>
but i'm only familiar with the mainline stuff
<hardik_>
i think i'm doing something silly mistake ....this CMDLINE in parameter is to do kernel configuration ...and i'm trying to set u-boot variable there
<mmind00>
hardik_ beeble: yes rk3188 can now also use mainline uboot ... but of course that relies on a devicetree being available for the board and rk3188-boards in their kernel 3.0 days were still using boardfiles
<hardik_>
mmind00, yes
<hardik_>
then i need to go for latest avaialabe kernel for rk3188
<mmind00>
hardik_: also, most board follow Rockchip's reference design pretty closely, so you should even be able to see some output when using the radxarock board that we currently support there
<hardik_>
i have custom board based on olimex rk3188
<hardik_>
Ok, i have main work to create some partition on emmc ...1) recovery + readonly 2) user space 3) backup
<hardik_>
i can create partitions but don
<hardik_>
*don't know about recovery and read only
<hardik_>
if anyone experienced the same ..plz share

why we need both images kernel.img and boot.img to boot rk3188 ?
<phh>
well, there are two configurations for rk3188 bootloader, either just boot.img which is kernel + initramfs, or kernel.img + boot.img, in which case boot.img is used only for initramfs, not kernel, to save space with recovery
sunxi_fan has joined #linux-rockchip
<hardik_>
phh: boot.img consist of kernel image + ramdisk
<hardik_>
..right?
<phh>
well, it's not supposed to contain kernel when you have a kernel.img
<hardik_>
phh: means we don't have to do "mkbootimg --kernel RK3188-SOM/arch/arm/boot/Image --ramdisk initrd.img -o boot.img"
<hardik_>
*when using kernel.img
<phh>
yes, --kernel /dev/null
<phh>
that's what I remember at least, I could be wrong
<hardik_>
i'm not able to find any initramfs case in any guidline........everyone using ramdisk
<hardik_>
*for rk3188
<phh>
initramfs is the same as ramdisk
<phh>
well rather, ramdisk is something that has been obsoleted like a decade ago, and everyone is actually using an initramfs
<hardik_>
RK3188-SOM/arch/arm/boot/Image and kernel.img is same ...right?
<phh>
hum, no, I think kernel.img has an additional header
<hardik_>
for kernel.img using olimex kernel and all other rockchip loader(uboot),parameter.emmc, boot.img from manifest
<hardik_>
and technique to flash also from rk3188-manifest site
<hardik_>
so here kernel.img and boot.img (Image+initrd)................kernel.img and Image are different ......but no problem in booting and modules are working as expected
<hardik_>
i meankernel.img and Image from differnt kernel
