machybris for developers: exposing rockchip video and graphical hw acceleration in linux apps

[joe540]

Hey, sorry for the delay

I managed to install your DEB completely without breaking my LXDE/Xserver stuff.

sudo apt-get install lsb-release
wget  http://mac-l1.com/v0.1.2/machybris-rk3188_4.4.2-0.1.2_armhf.deb
sudo dpkg -i --force-all,confnew machybris-*_armhf.deb
sudo apt-get install -f

But now hwc_test complains:

rock@radxa:~$ sudo test_hwc
UMP: ump_arch_open() failed to open UMP device driver
hwc already has procs! now overriding...
width: 1024 height: 600
UMP: ump_arch_open() failed to open UMP device driver
ERROR: failed to open gralloc: (Operation not permitted)
test_hwcomposer: eglplatform_hwcomposer.cpp:33: void hwcomposerws_init_module(ws_egl_interface*): Assertion `0' failed.

and all GL ES related stuff complains also.

I added fb=vc:64-63 to my kernel cmdline, but I still have a framebuffer console while booting, not sure if this is normal?

CMDLINE:fbcon=vc:64-63 console=ttyFIQ0,115200 console=tty0 root=/dev/block/mtd/by-name/linuxroot rw rootfstype=ext4 init=/sbin/init mac_addr=de:ad:de:ad:be:ef initrd=0x62000000,0x00800000 mtdparts=rk29xxnand:0x00008000@0x00002000(boot),-@0x0000A000(linuxroot)

I had the sunxi-mali driver to work so EGL/GLES drivers are not necessary to me, as I have already working driver directly in linux.

I'd like to strip the EGL/GLES part of the package. Would you mind guiding me in the right direction?

According to " cat /var/lib/dpkg/info/machybris.list | egrep 'EGL|GLES|egl|gles' ", I removed everything related to EGL/GLES:

and the X11 configuration at /etc/X11/xorg.conf

I also commented the kernel modules things (mali, ump, mali_drm, drm) from the boot script (/usr/local/share/libhybris/libhybris.sh) to keep my mali kernel modules and removed the # set EGL_PLATFORM to default part

Is there anything else to remove? Is there anything I should keep to be sure?

Also, I'm not able to 'make' your player example:

h265player.cpp:33:34: error: ‘OMX_RK_VIDEO_CodingHEVC’ was not declared in this scope
...
h264player.cpp.text+0x5afe): undefined reference to `machybris_init'
collect2: error: ld returned 1 exit status

Would there be a way to use the h264 decoder directly in chromium, for example? I'm developing a web application that will be both accessible directly via a web browser but also embedded on a RK3188 based board. I will have to decode h264 video and want to find a way to use the VPU for that!

Thanks for your support and your super work!
Sorry if I'm still a linux-newbie!
