Thank you very much for the links - I was having trouble finding those definitive answers before.
If I read everything correctly, it sounds like Gstreamer is part of the Platform API and should be present on all the common profiles (handset/notebook/etc). It further indicates that V4L2 *might* be used to implement the GStreamer API's - but V4L2 might not be guaranteed to be present on any particular vendor's implementation. In other words, I probably should write to GStreamer interfaces. Did I read that correctly? That said, if I start writing to the GStreamer or V4L2 ioctls/interfaces on the latest handset image/simulator, are those drivers/API's functional enough at this point to get basic signs of life on a camera-like app - or are there known show-stopper bugs?

Please see a porting guide for more informaiton. http://wiki.meego.com/MeeGo_Porting_Guide#Video_imaging You just need to be aware of MeeGo compliance policy. MeeGo has two layers of APIs sets. One is called "MeeGo API" and the other one is "Platform APIs". http://meego.com/developers/meego-api MeeGo API is forward compatible and applications using the MeeGo API will be MeeGo compliant. Mobility is part of MeeGo API. Both MeeGo API and Platform APIs are common to Handset, Netbook and other profiles. So your app based on MeeGo Core OS will be running on all these platforms. http://meego.com/developers/meego-architecture/meego-architecture-layer-view Regards, Min From: qt-mobility-feedback-boun...@trolltech.com [mailto:qt-mobility-feedback-boun...@trolltech.com] On Behalf Of ext Fife, Matthew P Sent: Thursday, 2 December 2010 9:30 AM To: qt-mobility-feedback@trolltech.com Subject: [Qt-mobility-feedback] V4L2 on Meego Forgive the intrusion if this has already been answered, but is the QtCameraControl API going to be the only supported interaction with the cameras on Meego (handset)? I've found a number of conflicting threads on the topic... I had read somewhere that V4L2, or possibly gstreamer, would also be supported by lower/driver-level implementations for more direct access to the hardware. I was hoping to port an application written for V4L2 to the Meego platform. Also, if V4L2/GStreamer support is available - is that true for handset, netbook, or all Meego platforms or is each one going to possibly have different support? My app is most applicable to handsets, but it would be good to know in advance if it might work on the other Meego platforms. Thanks
