Black screen with ximagesrc

[Arnaud Loonstra]

What version of gstreamer?

Does something this work?

gst-launch-1.0 ximagesrc use-damage=false ! glimagesink (or ximagesink)

Does this work?

gst-launch-1.0 ximagesrc use-damage=false ! videoconvert ! x264enc ! 
av_h264dec ! glimagesink

Does this work?

gst-launch-1.0 ximagesrc use-damage=false ! videoconvert ! x264enc ! 
rtph264pay ! udpsink host=127.0.0.1 port=5000

gst-launch-1.0 udpsrc port=5000 ! 
application/x-rtp,encoding-name=H264,payload=96 ! rtph264depay ! 
avdec_h264 ! glimagesink

I don't know specifics about rtmp or flash muxing but if these above are 
working you know where to look...

Rg,

Arnaud
