I am building a program that uses the GStreamer c++ code to stream from a server to a client from a webcam input. On the server, while implemented in code, I basically run this pipeline:</div><div> </div><div><p>pipeline = GST_PIPELINE(gst_parse_launch("v4l2src ! video/x-raw-yuv, width=1280,height=800,framerate=30/1 ! ffmpegcolorspace ! smokeenc keyframe=8 qmax=40 ! udpsink host=192.168.1.100 port=1234", NULL));</p><p> </p><p>And on the client I run this:</p><p> </p><p data-focusfrompointer="true">pipeline = GST_PIPELINE(gst_parse_launch ("udpsrc port=1234 ! smokedec ! ffmpegcolorspace ! autovideosink", NULL));</p></div><div data-focusfrompointer="true">Now as always is the way, this has worked fine for me on three machines (all windows 8 with VS2012 and GStreamer 0.10 runtime and SDK installed) and now I have a fourth machine it HAS to work on and it won’t. It will initialise, give me part of a frame in the pop up windows with mostly green (but partially there) and then crash.
