how to fix run stagefright on ubuntu x86_64 built normally?

[callm...@gmail.com]

I'm trying to run stagefright on linux environment `x86_64`.  

I built android-9.0.0-r35 as `x86_64`, and compiled kernel with binder, ashmem configuration, but it didn't work.

My environment is Ubuntu14.04 64bit, I compiled and install new kernel 4.20.17.

According to https://source.android.com/setup/build/building , I did below first.  I set the build environment as x86_64.

$ source build/envsetup.sh
$ lunch aosp_x86_64-eng
$ make -j4

I Also built stagefright like below.

$ cd [AOSP sourcecode]/framework/av
$ mma -j4

After that, I made a symbolic link for runtime-environment.

$ ln -s [AOSP sourcecode]/out/target/product/generic_x86_64/system /system

Next, I download newer version kernel, 4.20.17, and copied my original configuration file, and add options, compiled, and install it.

$ cp /boot/config-4.4.0-142-generic .config

(.config file)
...
CONFIG_ANDROID=y
CONFIG_ANDROID_BINDER_IPC=y
CONFIG_ASHMEM=y
...

$ make menuconfig
$ make-kpkg --initrd --J 4 kernel_image
$ dpkg -i linux-image-4.20.17_4.20.17-10.00.Custom_amd64.deb
$ echo -e "KERNEL==\"binder\", MODE=\"0666\"\nKERNEL==\"ashmem\", MODE=\"0666\"" | tee /etc/udev/rules.d/android.rules

After that process, I rebooted my VM, and tried to run the stagefright.

$ /system/bin/stagefright -s sample.mp4


(waiting until ctrl+c)

But the result is `nothing`. The process didn't stop or finish.

I just want to know how to run stagefright on x86_64 environment.

(I don't want to ARM cross compile stagefright.)

AOSP version is pie_9.0.0-r35.

Is anybody know how to fix it and run stagefright on ubuntu x86_64 normally?

As far as I know, the 'stagefright' shell command located in frameworks/av/cmds/stagefright

is intended for unit testing on Android only, and in any case is unsupported.
