Question

Broadcasting from camera blocks other applications from using the camera!

hi everybody,

  Have been stuck with this for quite sometime.Here's what i'm trying to do.

I have a video capture device on a machine. I have written a windows application to capture the video from this device. While capturing, if i try to broadcast using flash it does not connect. If i'm already broadcasting and then try to capture then my windows application does not get the capture pin of the device. So, flash seems to be taking the capture pin. Is there anyway to broadcast using the preview pin on the device so that i can capture using my application. Or is there way where i can split the capture pin and give one to my app and one to the broadcaster. Thank you for the help in advance.

    Have you considered using getting more than video feed into your rig using a hardware video splitter? It might be more rugged than a software option. I've had three webcams all going into flash at the same time with no problems.

    Hmmm, i dont want to increase the cost on my hardware. Also, i have already

    developed the software. I am just not able to integrate the two. I think

    i'll try shifting the capture code into flash itself and do only the

    crossbar switching in my application.

    Hi

    Applications such as splitcam allow multiple applications to access the same video source. Just simply download splitcam and point it to your video capture device then point your applications to splitcam.

    Hi,

    But my application catches onto the crossbar interface (i'm working on a

    cctv interface). If i try to run this with splitcam my app crashes.

    Splitcam should work with crossbar too. There is a crossbar option under the file menu

    That's something you'd need to handle at the device driver level. There is no API in Flash beyond connecting up to the device and setting some basic device parameters... so I'm fairly certain that the rest is up to the OS and device driver.

    @Jay : is there anyway i can modify the flash broadcaster (which calls

    getcamera) to take only the preview pin since i dont want to capture in

    flash anyways.
