I searched in vlc full help and http://wiki.videolan.org/Media_resource_locator for MRL (media resource locator) format how to play jpeg-2000 stream (jp2 format) over udp but i was unable to find any information.
When i dump the stream to a file vlc plays the jp2 file in wrong frame rate.
I have successfully tried vlc with h.264 udp stream format.
vlc udp/h264://@:9000 --h264-fps=30
Best regards,
