Description

Turns out this is easy to run. Just start the wecam (as is done with the web-based player) and then run:

omxplayer 'http://localhost:9090/?action=stream

Playback smoother than on the web interface but there is a bit of jumpiness. And it eventually locks up.

Might play better with the raspicam that's on order....

Wrote the front end, but it's missing the startup of mjpeg-streamer. I need to add the call to piboxd (like in the web interface) to have mjpeg-streamer started before I try to connect to the stream. Probably needs a short pause or some mechanism to sync/validate the mjpeg-streamer server is running.

The web interface sends the command from this code: piboxwww/src/piboxwww/php/webcam.php:webcam(). The protocol is specified here: http://www.graphics-muse.org/wiki/pmwiki.php/RaspberryPi/MessageFlow.

I need to send an MT_STREAM, MA_START to initialize the process. Then send MT_STREAM, MA_END to stop it.

Done. The webcam can now play on the console. There is an app icon for it in the launcher. The code also carries a generic messaging function to piboxd. This function should eventually be migrated to libpibox.

Tested on hardware via package installation. Code committed and pushed.

Closing issue.
