Muhammad,
Do you mean that the video just disappeared on the second machine
while the service was running, or do you mean that it just didn't
appear during a second running with the SimpleHDVideoConsumerService?
If you mean a second running of the SimpleHDVConsumerService, does
vic appear at all (even without any video)?
If vic appears but shows no video, what media address appears at the
bottom of vic? Is it the same address that appears on the first
machine's vic?
Please check the contents of the Venues->Properties widget of the
receiving machine. Does it contain a reference to the DV stream? Is
it the same as the corresponding entry on the first machine?
Ensure there are no other *HDV* services left over from previous
attempts
Some other things to keep in mind:
- both machines need to be in a venue; its possible to add and
configure a service without being in a venue but you must be in a
venue with both machines to actually have a flow of media traffic
- if the receiving machine has entered a venue before the producer
machine generates a DV stream, then the receiver has no information
about the DV stream. This is due to the dynamic generation of the
media addresses for *HDV* services. You may have to re-enter the
venue with the receiving machine to update its knowledge of all the
available streams
- its possible that with a lot of testing (including starting lots of
new streams) in a particular venue, then that venue may have built up
a number of possible media addresses which the receiver could use. At
any time, only on of these addresses is the correct one. The unused
addresses should quietly timeout eventually but, in the meantime, it
may be better to try a different venue
