No discourse : query about blank stream

[James Linder]

Hi

This pipeline the network stream is blank when the valve is closed. Why ??

gst-launch-1.0 -v -e v4l2src device=/dev/video0 ! image/jpeg,framerate=30/1 ! \
    jpegdec ! \
    videoconvert ! \
    clockoverlay halignment=left valignment=top draw-outline=true font-desc="Sans, 12" time-format="%d %b %Y %H:%M:%S" ! \
    gdkpixbufoverlay location=rennisons.png alpha=0.5 offset-x=1800 offset-y=900 ! \
    textoverlay text=... ! \
     tee name=t ! \
     queue ! jpegenc ! multipartmux ! tcpserversink host=127.0.0.1 port=5000 \
     t. ! queue ! xvimagesink sync=false \
     t. ! queue ! x264enc speed-preset=ultrafast tune=zerolatency byte-stream=true bitrate=4000 ! \
     mux. pulsesrc device=0 ! \
     queue ! \
     audioconvert ! \
     audioresample ! audio/x-raw, rate=48000 ! \
     queue ! \
     avenc_aac ! \
     queue ! \
     mpegtsmux name=mux ! \
     valve drop=TRUE ! \
     filesink location='try.mp4'

Why is network stream blank.
They jpeg fiddle was taught to me to get 1080 from the camera
When valve is open everything works.
