Hi, We could succesfully port Gstreamer framework to Android going through the link <a href="http://gstreamer.freedesktop.org/wiki/GstreamerAndroid_InstallInstructions">http://gstreamer.freedesktop.org/wiki/GstreamerAndroid_InstallInstructions</a> Through adb shell, we could run gstreamer commands to view mp4 files as well as mpegts files using gst-launch command. To view the video/ausio, we used audioflingersink as well as surfaceflingersink. For this purpose, all the gstreamer related environment variables have to be exported manually through the adb shell. We would like to run the gst-launch as an application in the Android phone without exporting the variables using adb shell. Is there any method for this? I am exporting the following below mentioned environment variables in the adb shell. export LD_LIBRARY_PATH=/data/data/com.android.freedesktop.gstreamer/lib/ export PATH=/data/data/com.android.freedesktop.gstreamer/bin:$PATH export GST_PLUGIN_PATH=/data/data/com.android.freedesktop.gstreamer/lib/ export GST_PLUGIN_SCANNER=/data/data/com.android.freedesktop.gstreamer/bin/gst-plugin-scanner export GST_OMX_CONFIG_DIR=/data/data/com.android.freedesktop.gstreamer/conf/ export GST_REGISTRY_REUSE_PLUGIN_SCANNER=no Thanks & Regards Anees
