Hi All,

I am working on Displaying/streaming 2 UVC CAM's simultaneously. Below Command

gst-launch v4l2src device=/dev/video1 ! videoscale ! ffmpegcolorspace ! video/x-raw-yuv, width=320, height=240 ! videobox border-alpha=0 left=-320 ! videomixer name=mix ! ffmpegcolorspace ! autovideosink v4l2src device=/dev/video2 ! videoscale ! ffmpegcolorspace ! video/x-raw-yuv, width=320, height=240 ! videobox right=-320 ! mix.


Out of 2, /dev/video1 streams data but the second CAM /dev/video2 is ON after the command, but in my Display its pitch black.


Is this the correct way to stream multiple cams??

Kindly advice
