hi all,
according to mma,VideoControl.getSnapShop() can get image data on its display area;if i creat a player via Manager.creatPlayer("capture:video"),the method works well and get a image from the camera;when i creat a player via Manager.creatPlayer(URL), VideoControl.getSnapShop() failed and return null;

so,we can take a photo via mma,but the problem is that whether we can get a snapshot from a displaying video.

hi,
are you trying to get snapthot (to bytes/to output stream) of Image? - via getSnaphot() or record Video (to bytes/output stream) - via RecordControl?
or you want to "capture" (using Canvas/Graphics api) what is currently displayed in viewport in your application?

regards,
Peter

hi,
I could only guess, never tried myself,
download SUn WTK 2.5 Beta tool, install it (its very usefull, having lot of api and tools), go to install dir>apps>MobileMediaAPI and browser source files for "VideoPlayer", sample midlet shows how to implement getting snapshots form VideoControl from Form/Canvas,
it works with Sun WTK 2.5 emulator (which emulates video playback/snapshots), never tested on real nokia device yet,

Peter

hi,i have try sun wtk 2.5beta,.it also capture snapshot via camera with"capture://video",fortunately,when i modify the source code and make it capture snapshot from a playing video player,it also works!
when it comes to the real nokia devices such as N80,getSnapShot(null) returns a 69-byte array which creates a white spot image.
i have no idea about what to do next...
