1) about test-appsrc;
It does not crash but just shows nothing (back screen) with counter running in
VLC media player.

Only when I abort the VLC media player I get a GLib-CRITICAL.

When I run gdb after I have set 'export G_DEBUG=fatal_warnings' I only get the
following:

When I change the media_factory to:
 gst_rtsp_media_factory_set_launch (factory,
      "( appsrc name=mysrc ! videoconvert ! video/x-raw,format=I420 ! x264enc !
rtph264pay name=pay0 pt=96 )");

I get a white screen instead of a black one (but not alternating black/white)
and I do not get the 4:4:4 message.

Concerning gstreamer-git version. It was a checkout from 26 or 27-12.
gst-launch-1.0 --gst-version ==> GStreamer Core Library version 1.3.0.1

About the gst-launch-commands I will tell you more about the failure:

My command for the udpsrc was in all cases:
gst-launch-0.10 udpsrc port=5000 caps='application/x-rtp, media=(string)video,
clock-rate=(int)90000, encoding-name=(string)H264' ! rtph264depay ! ffdec_h264
! xvimagesink sync=false

and that did not work with the gst-launch-1.0 videotestsrc, and did work with
the gst-launch-0.10 videotestsrc.

I swear I could remember also seeing the 4:4:4 message when startup of
gst-launch-1.0, but I saw nothing when I reproduced it now.

In the combi videotestrsc with 1.0 and udpsrc 0.1 actually the 0.1 udspsrc
crashes with:
ERROR: from element /GstPipeline:pipeline0/GstUDPSrc:udpsrc0: Internal data
flow error.
Additional debug info:
gstbasesrc.c(2625): gst_base_src_loop ():
/GstPipeline:pipeline0/GstUDPSrc:udpsrc0:
streaming task paused, reason not-negotiated (-4)

Sebastian, when I try your gst-launch-1.0 udpsrc they both run ok (just like
you mentioned), although I do not seem to have xvimagesink for 1.0 but used
autovideosink instead.

I assumed that the resulting udp-stream (sink) would be the same in 0.1 and 1.
But it looks like its different, otherwise udpsrc of gstreamer 0.10 would not
crash at videotestsrc 1.0 (as it does not when I launch viodetestsrc in 0.1.)

If you have more questions I am more than welcome to help. Preferably this
weekend, because on monday I am going on a long holiday.
