Several problems in Gstreamer Android

[Jacques Bride]

Hello All

On Android and Gstreamer SDK, I also met the already exposed problem with
av_malloc defined both in ffmpeg and ffmpegcolorspace. I run ubuntu 12.04
and I wish to create an android player for H264using ffmpeg usiing
tutorial5

I went and see https://bugs.freedesktop.org/show_bug.cgi?id=59485 which
provides a new ffmpegclorspace library.

Unfortunately it's not a static version but a .so version.
Looking at the comments, I downloaded the tar.gz plugin-base package
containing the fix from :
http://cgit.freedesktop.org/gstreamer-sdk/gst-plugins-base/commit/?id=8599175207e044ad5a46edc81ed9166dd3175157
I also installed androgenizer from
http://cgit.collabora.com/git/android/androgenizer.git/

Unfortunately, I did not manage to run ./autogen.sh to create the configure
script, got message saying missing common/gst-autogen.sh....

I would be very grateful someone kindly share with us a fixed static
version of this lib please?

Jacques
