Problem Streaming webcam

[Cylarcy]

Hi all

i am newbie in linux and i am trying to stream my Webcam from the Rpi. Please bear in mind that i followed i think all the tutorials in the forum

I have tried so far

motion, ffmpeg and GStreamer

Although motion is not streaming i tried it to play around and i had some success but i could only get a very dark image and did find a solution.

ffmpeg i couldnt get it to work

I tried to get GStreamer to work and open the stream in vlc but the only thing i get is a green screen

Can you help to get atleast GStreamer to work. i really dont know where to go from here. ofcourse i googled, checked the forum etc

thank you

Show first lsusb and the last lines of dmesg so that we can see what camera you are using. I am just testing my webcam also and it seems to work, but the quality is bad.

What make and model of webcam are you using?

Have you examined the webcam properties using the v4l2-ctl command?

Some camera work better than others but safe to say none of them are better than "satisfactory" and thats if you don't set the bar too high. Crippled USB subsytem (it drops packets) and a puny processor means the Pi doesn't do webcams very well. The USB is betting better with ever improving drivers but personally I'm not holding my breath for it to work properly. I'm holding out for the dedicated camera module (which doesn't use USB and makes use of the very good GPU in the Pi).

I managed to get the camera working somehow using the arch image but quality is really bad. I guess i should play with the settings more but the camera works nonetheless
