Decode H264 stream with Gstreamer [windows]

[Pyrodrag]

Hello community. I try to display an rtp stream encoded in h264 on a computer
(send by a camera) . I use gstreamer (in command line) for windows (sorry I
didn't have the choice to use it on windows). I success to display correctly
with this line on Linux (ubuntu):
gst-launch-1.0.exe -v udpsrc port=5008 ! application/x-rtp, payload=96 !
rtpjitterbuffer ! rtph264depay ! avdec_h264 ! textoverlay
text="192.168.120.2" ! fpsdisplaysink sync=false text-overlay=false


But when I try to use the same line on windows, it works but they are some
glitch on the video( luminosity problem, color problem etc), it seems to
have difficulty to decode, depay or support H264 format. I search since 2
weeks how to resolve this, but I found nothing. Someone has idea of what is
wrong on my line or what option that I don't use and it necessary in windows
for a best H264 decoding?

Thanks

Best regard

I wasn't able to get your pipeline to work on a Windows system as-is. However, the following modified pipeline worked for me:

gst-launch-1.0.exe -v udpsrc port=5008 ! application/x-rtp, payload=96 ! rtpjitterbuffer ! rtph264depay ! video/x-h264,stream-format=(string)byte-stream,alignment=(string)nal ! h264parse ! avdec_h264 ! textoverlay text="192.168.120.2" ! fpsdisplaysink sync=false text-overlay=false

I added the stream format description and the h264parse element . Your format description may be different than mine so if the one above doesn't work you may have to tweak that.

Thanks, it works perfectly now. The order of the different "plugin" is very
important for gstreamer ? I search what is the reason for my line doesn't
work. Now I try to add some options. If I have another problem, I ask you ;)
