Hello,
we successfully managed to get video stream into Gem/pix_video with v4l2loopback booth with gstreamer and ffmpeg, we used ffmpeg at the end, maybe some help by there : http://wiki.labomedia.org/index.php/AstroFluxTechnique#Pour_Debug http://wiki.labomedia.org/index.php/AstroFluxTechnique#Minicaster_Stream we used a compiled version of v4l2loopback https://github.com/umlaeute/v4l2loopback to get the latest version and a static version of ffmpeg or a self compiled version of ffmpeg in function of the codec needs

Hello,
I would like to use pdgst to play a video stream in Gem.
I tried with the vlc plugin : device tcp://192.168.1.101:5555
... but like with : $ vlc tcp://192.168.1.101:5555
... i got a black screen.
I tried with gstreamer : $ gst-launch-1.0 tcpclientsrc host=192.168.1.102 port=5555 ! h264parse ! avdec_h264 ! xvimagesink
... and i get the stream and everything is OK :)
So, I decided to use v4l2loopback to get the stream on /dev/video1, but after : # modprobe v4l2loopback $ gst-launch-1.0 tcpclientsrc host=192.168.1.102 port=5555 ! h264parse ! avdec_h264 ! v4l2sink device=/dev/video1
... i got : Setting pipeline to PAUSED ... Pipeline is PREROLLING ... ERROR: from element /GstPipeline:pipeline0/GstTCPClientSrc:tcpclientsrc0: Internal data flow error. Additional debug info: gstbasesrc.c(2943): gst_base_src_loop (): /GstPipeline:pipeline0/GstTCPClientSrc:tcpclientsrc0: streaming task paused, reason not-negotiated (-4) ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... Freeing pipeline ...
So I can't use pdgst nor pix_video to read the stream.
I also tried with : $ gst-launch-0.10 tcpclientsrc host=192.168.1.102 port=5555 ! h264parse ! avdec_h264 ! xvimagesink
but gstreamer (gst-launch-0.10) can't find the module "avdec_h264" (and i can't get ffdec_h264 on my system, dont't know why yet). Any suggestion to get the stream in Pd/Gem ? Thanx. ++
