we are trying to use web cam for a security application:images transfer to the internet in case of alarm.
The web cam example works great but it would be nice to add the possibiliy to decrease the size of data due to reduce transfer time/cost.
Is it possible,for example,to reduce the data size using gray scale images or jpg/png format?
How can we access web cam primitives to get raw data? It would be useful to transfer directly raw data (without saving it locally on a file) and process it afterwards on a PC.
Thanks in advance.
