[gst-devel] rtph264pay cannot connect to rtph264depay?

[Chih-Wei Huang]

Hi,
I'm trying the H.264 RTP support of GStreamer.
I issued the following test command and got errors:

gst-launch -v videotestsrc ! x264enc ! rtph264pay ! rtph264depay ! 
ffdec_h264 ! videoscale ! video/x-raw-yuv,width=352,height=288 ! 
ffmpegcolorspace ! ximagesink

FREEING pipeline ...


If I removed the rtph264pay & rtph264depay in the above pipeline,
I could see the test image.

All the gstreamer core, base and plugins are CVS 20070511,
while the x264 is snapshot-20070322.
The OS is Fedora 6.

Any idea?
