  • Solution for VB6 to broadcast Webcam

    14 septembre 2018, par vantrung -cuncon

    Sorry, I know VB6 is decades ago, but I’m in a situation that I have to use VB6 to deliver live webcam stream beetween 2 PC in Server - Client Model program. Vb6-code holds the connection then I have no choice but to transfer all data via that connection.

    I’ve tried weeks for this, uncountable approaches but went to nowhere.
    My efforts focused on 3 major approaches :

    1/ Use ffmpeg to record live webcam as ".avi" file on hard disk, transfer parts of file to other end & play it. But I’ve stucked with a media-player that can play a "being written" avi file.

    Windows Media Player control told me "file already in use..." & VLC Plugin can’t even be added to VB6 (axvlc.dll).

    2/ Use ffmpeg to save live webcam as avi file, transfer each bit of that file to the other end, then in other end, extract 24 images / second from the avi to display continously in a picture box.
    This approach is ok except that my hard disk get fulled of images in a time of wink and my program get very slow before hanging.

    3/ Use ffmpeg to stream the live webcam to a rtp-port like this :

    ffmpeg -f dshow -i video="Lenovo EasyCamera" -vcodec mpeg2video -pix_fmt yuv422p -f rtp -an rtp://224.1.2.3:8191

    I’ve successfully watch the stream in VLC, but VLC(axvlc.dll) refused to be integrated into ancient VB6. And more important, I don’t know how to redirect/reroute the rtp stream to other PC with VB6.

    Any one please light me up ? (Any 3rd party component is welcomed)
