Some issues of running gstreamer-android in the emulator

[Fang Bao]

Hi,

I tried the gstreamer-android in the emulator running on Ubuntu 10.10 amd64 and followed the documents < http://gstreamer.freedesktop.org/wiki/GstreamerAndroid_InstallInstructions>.
Android started playing audio/video failed and printed follow errors:

E/GstDriver(  369): Can't create surfaceflingersink
V/GstDriver(  369): add surfaceflingersink to playbin
E/GstDriver(  369): Can't create audioflingersink
V/GstDriver(  369): add audioflingersink to playbin
E/GstDriver(  369): Pipeline not initialized

I found the plugins surfaceflingersink and audioflingersink were not built in default configuration.

1. audioflingersink is defined as optional tags in gst-plugins-bad/sys/audioflingersink/Android.mk.
So I issue the follow commands to build this library and added it to Android system image:

make libgstaudioflinger
make snod

2. surfaceflingersink is removed from Android.mk. The details is as follow:

    Remove -android2 buildsystem hooks, surfaceflingersink is in gst-android now

diff --git a/Android.mk b/Android.mk

So I reverted this change and build whole system again.

After above two steps, the surfaceflingersink and audioflingersink were created successfully and pipeline were initialized ok.

I have a question why setting audioflingersink library tag to optional?
