[gst-devel] udpsink issues

[Greg Wunder]

Running on Windows right now, but my app & the underlying framework seem to produce the same error on Linux & Mac.
Still need to test more, but I'm running with GStreamer 0.10.26 & udpsink 0.10.17.
I just upgraded the udpsink to the latest I'm aware of (0.10.24).
Started investigating the debug output yesterday.
Will let you know if I find more info to the problem I'm receiving as this is odd.
Thanks for all your help!

Greg

that is pretty odd... which version of gstreamer are you running and in
which system? (udpsink can have some problems on windows, depending on the
version of gstreamer that you are using)

have you tried a identity before your udpsink just to be sure that data is
flowing trough your pipe? (i must admit that given the simplicity of the
pipe i don't know why it wouldn't go to play... but anything is possible
:-)).

you can try debugging with a --gst-debug=udpsink:5 or --gst-debug=5 to see
if anything odd appears on the debug.
