Yes. in the web interface you have the Diagnostic sections. Press gstreamer, and UAVcast button. That will tell me much more what`s going on.

hello Bernt,
Hope you are doing well. sorry for the delay...finally got some time to reconfig my pi.

I have preformed a clean install image for my pi. (latest stretch image from emlid), and reinstall UAVcast. Then I setup the C920 just like before with same result. here is the gstreamer output:

04/11/2017 16:23:28
C920
WARNING: erroneous pipeline: no element "omxh264enc"

Do you need more info/log to troubleshoot this ?
ive check the list of usb device tap, the pi do detect the c920 camera.
Ive also order a pi cam just in case so that I can isolated the problem. it's on its way.

Many thanks!

Has anyone interfaced UAVcast with a BeagleBone Blue running Ardupilot?
Any ideas on the best way to connect Telemetry? USB networking mode perhaps? Or maybe RPi GPIO pins to one of the Blues built in Serial/Uart ports?
Or would Wifi be sufficient?

Thanks for any ideas~

[unknown] I will check this when im back home next weekend. Im currently on a business trip.
Can you try to set diffrent resolution; for example

width:640
heigth:480
Bitrate: 900000

See if the output is diffrent.

stavros

I'm getting the same error

C920
WARNING: erroneous pipeline: no element "omxh264enc"

I've also tried to set a different resolution (e.g. width:640 - heigth:480 - Bitrate: 900000) but I still get the same error.

Its probably an easy fix, but i will not be able to look into this before next weekend.
Can you try to start camera manually by typeing the commands in the link below directly into the RPI shell

https://github.com/UAVmatrix/UAVcast/blob/master/script/camera.sh

UAVcast uses these function to start camera based on what you selected in the Web Interface.

I've tried to start my C920 camera manually using the the C920 function from the camera.sh script, but got the same error.

WARNING: erroneous pipeline: no element "omxh264enc"

The command I've run in the RPI shell was:

gst-launch-1.0 -v rtpbin name=rtpbin v4l2src device=/dev/video0 \
        ! video/x-raw,width=640,height=480,framerate=30/1 \
        ! queue \
        ! omxh264enc target-bitrate=500000 control-rate=3 \
        ! "video/x-h264,profile=high" \
        ! h264parse \
        ! queue max-size-bytes=10000000 \
        ! rtph264pay pt=96 config-interval=1 \
        ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 \
	! udpsink port=5600 host=10.19.180.10 ts-offset=0 name=vrtpsink rtpbin.send_rtcp_src_0 \
    	! udpsink port=5060 host=10.19.180.10 sync=false async=false name=vrtcpsink udpsrc port=5000 name=vrtpsrc \
        ! rtpbin.recv_rtcp_sink_0

I'm using the latest Emlid image for Navio2, if that helps at all...

DorHalperin1 i cant open the web brower configuration from my pi 0 on my desktop

Check if you can open it locally from RPI browser http://127.0.0.1

Good day. We are on our way to do the UAVcasting but when we try to start the casting we got an error on gstreamer part. Could you help us solve this problem ? Thank you. Have a good day.

kevinpallado

and also while following the tutorials I got this error while executing the command in windows terminal
