Thank you, Yair. I was able to get a ton of debugging output with your advice (and Tim's). My steps: Set GST_DEBUG=*:7 Then adding this to my command-line program execution: 1> out.txt 2>&1 eg: foo.exe 1> out.txt 2>&1 Now I will step through that. Happy to share it if anyone wants to see it. -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/
