Gstremer compatibility with android 10+ devices

[Purva]

Hi,
I am developing android application I am facing issues while live streaming
in android 10 devices.
App works fine with android 7 devices. Here is the error Error received from
decodebin0 : on Android 10 device,
===========================
Your gstreamer installation is missing plugin.
============================
../sys/androidmedia/gst-android-hardware-camera.c:1616:_init_classes Failed
to initialize android.hardware.Camera classes: Failed to call Java method:
java.lang.ClassNotFoundException: Didn't find class
"org/freedesktop/gstreamer/androidmedia/GstAhcCallback" on path:
DexPathList[[zip file
"/data/app/org.freedesktop.gstreamer.livestream.livestreaming-1/base.apk"],nativeLibraryDirectories=[/data/app/org.freedesktop.gstreamer.livestream.livestreaming-1/lib/arm64,
/data/app/org.freedesktop.gstreamer.livestream.livestreaming-1/base.apk!/lib/arm64-v8a,
/system/lib64, /vendor/lib64]]

I figured out that issues is with libgstandroidmedia.a which is prebuilt
file. Is there any way to get this file source code or modify this file so
that I can make this library compatible to Android 10 ?
 
I have been using gstremer source from below link
https://gstreamer.freedesktop.org/download/

Any help or guidance would be appreciated

The source code for the androidmedia plugin is available from
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/tree/master/sys/androidmedia 
<https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/tree/master/sys/androidmedia>.
A MR fixing the incompatibility would be very welcome.

Cheers

Any idea about how to install this plugin or compile this ?

The official GStreamer binaries are built using cerbero available from
https://gitlab.freedesktop.org/gstreamer/cerbero/ 
<https://gitlab.freedesktop.org/gstreamer/cerbero/>. The README contains
some information on how to use it.  Building for android is only
officially supported and known to work from a linux host.

The oficial binaries already contain the androidmedia plugin however due
to changes in Android 10, it seems androidmedia doesn't pick up some/all
of the codecs anymore.

Thanks for the help
The source which I have used is
 https://gstreamer.freedesktop.org/download/
And you are referring to different source.
Should I use different source for ndk compilation?
