Hi,<div> </div><div>I tried to play mpeg/mp4 files as an Application using eclipse environment by loading some of the libraries from Gstreamer. The main limitation is that it requires both audio sink(audioflinger.so) and video sink(surfaceflinger.so) to play the files and display it on the screen, When we tested it on the phone. we are able to hear mp4 audio perfectly but video is not displayed on screen. This is due to a permission error on video sink - surfaceflingersink.</div><div><div>08-01 16:11:31.335: W/ServiceManager(1542): Permission failure: android.permission.ACCESS_SURFACE_FLINGER from uid=10076 pid=15466</div> <div>08-01 16:11:31.335: E/SurfaceFlinger(1542): Permission Denial: can't access SurfaceFlinger pid=15466, uid=10076</div><div> </div><div>How to resolve this permission error?</div> <div> </div><div>Regards</div><div>Anees</div> <div class="gmail_quote">On Tue, Jul 3, 2012 at 7:23 PM, Anees Alappat <<a href="mailto:aneesalappatt@gmail.com" target="_blank">aneesalappatt@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5">Thanks for your help.

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 -------------- next part -------------- An HTML attachment was scrubbed...

Is there any method for > this? Maybe some of these suggestions could be useful to you: - Writing a wrapper in shell script (eg: gst-launch.sh) that does the variable exports before calling the actual gst-launch executable. Execute the script invoking /system/bin/sh <script-name>. - Writing a wrapper C program that does the variable exports using setenv() and then exec() the actual executable. - Modify the gst-launch sources to add the setenv()s there.
