http://wiki.laptop.org/go/GStreamer#Using_gst_at_the_command_line 

Currently looking at ways to use the camera preview pipe as a method of video recording through the WebOS GUI by diverting it to the filesystem.

File of interest: /usr/lib/luna/luna-media/palmInitMedia.js

More on the camera module: http://www.st.com/stonline/products/literature/bd/14404/vx6852.htm

Relies on Prelease for launching shell scripts. Use Flashlight App! to install it before attempting to run.
 
Currently stop button doesn't work.

Note: Current versions of Prelease available through webOS QuickInstall and Preware no longer support the exploit to pass abritrary code, so this shouldn't work --[[User:Prenos|Prenos]] 16:59, 9 September 2009 (UTC)

== ToDo ==
1.) Figure out proper way to freevideosink via a homebrew app (killing gst-launch properly) (probably will involve invoking a custom service) 
2.) Mux in sound from alsasrc 
:"gst-launch alsasrc ! alsasink" will give you sound from the mic playing back through the speakers, verifying alsasrc. It quickly loses resolution though, and starts giving "can't keep up with audio source" errors. --[[User:Zinge|Zinge]] 08:23, 7 August 2009 (UTC)

:"gst-launch alsasrc ! wavenc ! filesink location=/media/internal/downloads/test.wav" will record audio no problem. --[[User:Cpcrook|Cpcrook]] 17:36, 7 August 2009 (UTC)
:"gst-launch camsrc ! palmvideoencoder ! avimux name=mux ! filesink location=/media/internal/downloads/foo.mts alsasrc ! mulawenc ! mux." will mux audio and video, though the timing was a bit off when I played it back. --[[User:Muchtall|Muchtall]] 18:15, 7 August 2009 (UTC)

3.) Implement preview screen (possibility: send video through palmvideosink, then to palmvideoencoder so its still accessible for preview?) 
4.) Get Videos app to display recorded video files (if anyone knows why the doesn't work now, please add it here, because it should work but it doesn't) 
5.) Video conferencing via UDPsink? 
6.) Get 720x480@30fps working (TI claims this is possible with the current hardware). This seems to require recompiling camsrc with palm's 'capabilities template' removed or adjusted(palm offers both the base v4l2 drivers as well as their patch to compile the camsrc plugin on their opensource website). There's also a comment in palmInitMedia.js that the driver only supports up to 480x320, but v4l2 is documented to handle higher resolutions. Will also requre installing another video encoder. --[[User:Prenos|Prenos]] 20:10, 27 August 2009 (UTC)

Relies on Prelease for launching shell scripts. Use Flashlight App! to install it before attempting to run.
 
Currently stop button doesn't work.

== ToDo ==
1.) Figure out proper way to freevideosink via a homebrew app (killing gst-launch properly) 
2.) Mux in sound from alsasrc 
:"gst-launch alsasrc ! alsasink" will give you sound from the mic playing back through the speakers, verifying alsasrc. It quickly loses resolution though, and starts giving "can't keep up with audio source" errors. --[[User:Zinge|Zinge]] 08:23, 7 August 2009 (UTC)
3.) Implement preview screen (possibility: send video through palmvideosink, then to palmvideoencoder so its still accessible for preview?) 
4.) Get Videos app to display recorded video files 
5.) Video conferencing via UDPsink?

At your command line (after [[Portal:Accessing_Linux|accessing linux]]):

(make sure FS is rw) 
<source lang="bash">
mount -o remount,rw /
gst-launch camsrc ! palmvideoencoder ! filesink location=/media/internal/downloads/foo.mts

- No GUI 
- No sound (need a muxer plugin? verify alsasrc works) 
- Frame rate seemed pretty decent too. 
- Video is H.264 at 480x320. 
- Image is rotated 90 degrees CCW

Currently looking at ways to use the camera preview pipe as a method of video recording through the WebOS GUI by diverting it to the filesystem.

File of interest: /usr/lib/luna/luna-media/palmInitMedia.js

More on the camera module: http://www.st.com/stonline/products/literature/bd/14404/vx6852.htm

== ToDo ==
1.) Figure out proper way to freevideosink via a homebrew app
2.) Implement preview screen (possibility: send video through palmvideosink, then to palmvideoencoder)
3.) Video conferencing via UDPsink?

At your rooted command line:

(make sure FS is rw) 
<source lang="text">
mount -o remount,rw / 
gst-launch camsrc ! palmvideoencoder ! filesink location=/media/internal/downloads/foo.mts 
mount -o remount,ro / 
</source>
- No GUI 
- No sound (need a muxer plugin? verify alsasrc works) 
Frame rate seemed pretty decent too. 
Video is H.264 at 480x320.
