udp streaming and webm

[Trevor Clarke]

Still no luck:

$ gst-launch-1.0 videotestsrc ! videoconvert ! vp8enc end-usage=cbr
error-resilient=partitions keyframe-max-dist=10 auto-alt-ref=true ! webmmux
min-index-interval=10000000 ! chopmydata max-size=9000 ! udpsink
host=127.0.0.1 port=5432 & sleep 3 && gst-discoverer-1.0 udp://
127.0.0.1:5432

An error was encountered while discovering the file

 Could not determine type of stream.



But this works (changed sleep to 0)

$ gst-launch-1.0 videotestsrc ! videoconvert ! vp8enc end-usage=cbr
error-resilient=partitions keyframe-max-dist=10 auto-alt-ref=true ! webmmux
