How to capture an image

[dasun]

I want to capture an image from the camera while streaming is running. How can I do it with libstreaming?

Hi,

If you use the mediacodec branch (I will merge it with master when it will be more stable), you could do that with some modifications of the lib: look at onPreviewCallback(...) in VideoStream.java, you have a buffer there that contains the last image (more or less...) from the camera (which is given to a MediaCodec instance).

The image is encoded in the NV21 color format, so you will also need to convert it back to RGB :(

If you are using the master branch, well you can't do that, you need to stop the stream first...

Hi fyhertz,

try1 :
I wanted to capture image while streaming video for this i have edited example3 and removed library from libs and added libstreaming master project library. I edited the videostream.java and Session.java file to capture image and it works but further when i try to stream the video application hangs(streaming does not takes place).

try2: - using library.jar file

i have used this and streaming works supper fine thank to you. Further if i want to capture image from stream i cant do it as obvious that i wont get acces to camera.

Is there any way that we can work with the master project where we can implement this.

any idea or any way or any sort input you have will be great so that even i can share things if i am able to achive this.

any ways thanks a lot for your wonderful effort.

regards,
