How to connect webcam to playbin2 ?

[Won J Jeon]

Hello all,

I'm trying to modify playbin2 so that it can use a webcam's captured frame as a  source to playbin2.

I notice that playbin2 - actually uridecodebin defines a file descriptor (fd://) to specify the source, so I wonder if this could be used for connecting the webcam's captured frame.

I appreciate if you have any comments or suggestions.

Regards,

Won

What do you want to really do. Would perhaps using camerabin be more appropriate? What features in playbin2 do you need to be applied to the live-camera stream?

Dear Stefan,

Thanks for your response. I'm modifying the existing code, so reusing playbin2 is one of constraints that I have.

Basically I'd like to use a captured frame (as in camerabin's source) as an input of playbin2.

Well if you are not able to share more about what you want to do, I won't be able to help you any futher. With the given input I can only repeat that sticking live camera input into playbin2 is weird.

Dear Stefan,

If I use camerabin, how can I disable a popping preview window and instead copy the captured frame to my own image buffer in the application?

Regards,

Won

I don't knopw how you are using it. Is your code online somehwere? If an extra window pops up, you want to take the video-sink under your control.
