[Elphel-support] Gstreamer JP4 plugin issue

[Ángel]

Dear elphriends,

I am playing with the GStreamer JP4 plugins.

I call gst-launch with the following pipe (previously I set the camera up to
1920x1088 JP46 mode):

$ gst-launch-0.10 rtspsrc location=rtsp://xxx.xxx.xxx.xxx:554 ! rtpjpegdepay
! jpegdec ! queue ! jp462bayer ! queue ! bayer2rgb2 ! queue !
ffmpegcolorspace ! videorate ! "video/x-raw-yuv, format=(fourcc)I420,
width=(int)1920, height=(int)1088, framerate=(fraction)25/1" ! autovideosink

as seen on

http://blogs.elphel.com/2009/11/interfacing-elphel-cameras-with-gstreamer-opencv-opengl-and-python-get-profit-of-dsp-or-gpu-based-optimisation-control-camera-settings-from-python-application-or-human-interface-device-hid/

and I get the following error:

(gst-launch-0.10:4928): GLib-WARNING **: g_set_prgname() called multiple
times

El flujo es en vivo y no necesita PRECACHEADO ...

Translation: ERROR on element
/GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc0: internal data
flow error

The pipe:

gst-launch rtspsrc location=rtsp://xxx.xxx.xxx.xxx:554 latency=40 !
rtpjpegdepay ! jpegdec ! autovideosink

shows the undemosaiced JP4 stream successfully.

Thank you,

Ángel.
