vidsrc in uvch264 fails

[Sneha Murganoor]

Forgot to mention

I read that vfsrc must be linked and in playing mode (or set
auto-start=true).. so captured the below scenario too.

When i try both the sources vidsrc and vfsrc, i get only vfsrc window.

gst-launch-1.0 -v -e uvch264src device=/dev/video0 name=src
auto-start=true  src.vfsrc ! queue !
video/x-raw,format=\(string\)YUY2,width=320,height=240,framerate=10/1 !
textoverlay text="Capture from vfsrc" font-desc="Sans 24" ! xvimagesink
sync=false src.vidsrc ! queue ! video/x-h264 ! h264parse ! avdec_h264 !
textoverlay text="Capture from vidsrc" font-desc="Sans 24" ! xvimagesink
sync=false
