any plan to simplify the build steps? about v4l2test HOT 3 OPEN

if you cloned google AOSP source code, and switch to tag android-4.4.4_r2.0.1, I think it's possible to build v4l2test.

under android source dir:

1. source build/envsetup.sh
2. lunch (and select a combo, ex. aosp_arm-eng)
3. make -j8
4. cd v4l2test
5. mm -B -j8

if not using A33 platform, remove
-DUSE_MEDIASERVER_H264ENC
-DPLATFORM_ALLWINNER_A33
from Android.mk

and add
-DUSE_MEDIACODEC_H264ENC

this will disable allwinner A33 cedarx hw encoding code, and support android mediacodec hw encoding.

Hi,
"It seems to be almost impossible to build it without the A33 SDK."
I think it can be build on other platforms. i build success on iMX platform

from v4l2test.

build ffmpeg/x264 looks correct , but failure when mm instruction in A33/Android6 SDK:
