ffdec_h264 problem on windows

[giorgino]

 Hi all,
       I downloaded OSSBuild 0.10.6 using it under windows.
I have in a Linux PC the following pipe

gst-launch -v gstrtpbin  v4l2src ! ! video/x-raw-yuv,width=320,height=240,
framerate=15/1 ! videorate ! ffmpegcolorspace ! x264enc byte-stream=true
bitrate=128 ! rtph264pay pt=99 ! udpsink port=5000 host=192.168.100.194

In reception I use a java program using java-gstreamer 1.4 in order to decode
the stream and visualize it in swing videocomponent. In reception the pipe is

gst-launch udpsrc caps=application/x-rtp,media=video,clock-rate=90000,
encoding-
name=H264 port=5000 ! rtph264depay ! ffdec_h264 ! ffmpegcolorspace !
autovideosink  

If I start first the java program and after the send pipe on linux the
program
works well although sometimes it crashes saying that there is a problem on
lib
avcodec. If I start the Linux pipe and after the java program, the video
isn't
fluent and in the console I can see

The same code instead works well without any problem under Linux, so the
problem is related to windows OSSBuild library. How I can solve it?


Thanks in advance and have a nice day

I think the problem is in rtph264depay that doesn't work well on
windows, look at the following bug:

https://bugzilla.gnome.org/show_bug.cgi?id=633831

in you are on windows xp you should see a crash too, the crash is not
present on windows 7

instead of autovideosink try:

d3dvideosink sync=false

based on my experience you should see this error after a while in any
case and this will impact on the quality of the video you see

I think the problem is gstreamer on windows and not OSSBuild,
