Despite its challenges, cloud gaming is growing its share in the gaming market by attracting more players. This has led to an increasing number of researches trying to overcome cloud gaming's challenges, including the required high bandwidth and low latency, to make cloud gaming more practical and profitable. To perform this research, researchers need a testbed to evaluate their ideas and find the best solutions. Currently, GamingAnywhere is the only open source platform and testbed to serve

In this testbed, the screen capturing module is fundamentally a DirectShow filter and, hence, can be tuned for any DirectShow compatible video game. The testbed also facilitates the measurement of delay and quality as the video is processed through its modules.
