Re: [Java-player-users] Camera compress data never ready

[<mar...@gm...>]

I tried with your option but I didn't get anything, I also tried with the
runThreaded but is always the same, there is no data ready. I don't know wh=
y
with the camera device (no compress) works fine if I'm using the same
routine but the camera compress just read once.

Thanks
Marcela

I think the problem is that you set PlayerClient to run not threaded, then
after the initial client.readAll(); you then enter the infinate loop:

while (!cami.isDataReady ());

and since there is no reading inside the loop to check for new data from
player once this loop starts it will never end.  I think something like:

while (!cami.isDataReady ())client.readAll();

may work.

thanks

John
