What do you mean? to launch the application? to make the soft-keyboard
come up? to enable an hardware keyboard input?

Till now the workaround is to use directly /dev/video0 or whatever
video source you have.. you can do directly v4l or you can use
gstreamer/ffmpeg to get the video frames to show on screen or encode
videos..
In this case you need to add gstreamer/ffmpeg as libraries in your
application.

Remember to add the correct Android permission! (like USE_CAMERA)
otherwise your application will not be able to open the video source
in a standard Android device.

Good luck! I'll have to manage the same in a while..
