[Live-devel] Merging images...

Tue Dec 13 14:14:47 PST 2005

Hi Ross,

I wrote an application based on live555 which streams images from an 
MPEG camera. When I start two instances from this app collecting images 
from two separate cameras we see that the images are merging from one 
camera into the other. Please find the logs attached. We compute 
checksums on video/audio packets what we actually get from "you" 
(addData1()) before storing the data. Look at the lines in the two logs 
with the same checksums showing that contents are identical (I marked 
the lines with a <- ).
