strange problem on Nokia 770

Hi!
I observed a strange problem on Nokia 770.

After I playback video using the default video player on Nokia 770,
I can't playback video using gst-launch or the media player that I have
developed.

If I reboot the device, I am able to playback video using gst-launch/my
player.

Any pointers on how to deal with this problem?

Regards,
Vinod

Hi,

please tell use whats the error you get. Have you closed the video
player? Try to stop the media-engine process.

Hi Stefan,
There are no errors that I see on playback of video file using
gst-launch-0.10. Its just that the video is not seen.

I closed the video player before trying gst-launch.
But, I am not aware of the media-engine process. How can I stop and start it?

Regards,
Vinod

/etc/osso-af-init/media-engine stop

this is from the top of my head, so look around, if the filename is not 100%
correct.

Hi Stefan,
Thanks for the pointer.

I tried using this
/etc/osso-af-init/osso-media-server [stop|start].
But that didn't help in getting back the video.

I found out that the following command can be run to get video back. But only
problem is that it needs to be run in sudo mode.
/usr/sbin/dsp_dld -m /lib/dsp/modules/mpeg4.cmd

Now, I can't expect every user of N770 to have sudo access. So, I'm still
stuck with the problem.
Is there any work around possible?

Regards,
Vinod
