Android emulator

[webpolis]

Hi guys

Even if I know running in emulator isn't officially supported, I wonder why some people could make minicap work with emulator running on API 23. I have an Intel Atom x86 image with sdk 23, but when running minicap to grab a screenshot, I get

nico@nico:~/dev/stf (master)$ adb shell LD_LIBRARY_PATH=/data/local/tmp /data/local/tmp/minicap -P 720x1280@720x1280/0 -s

Minicap info cmd shows

And I'm running following emulator

Available Android Virtual Devices:
    Name: android-23
  Device: Galaxy Nexus (Google)
    Path: /home/nico/.android/avd/android-23.avd
  Target: Android 6.0 (API level 23)
 Tag/ABI: default/x86
    Skin: 720x1280

Please advise which is the right emulator setup to make minicap work.

Thanks
