In case of DRM streaming, decrypt session can start just after receiving the header, and it doesn't need to wait for the entire content. However, current API of DRM framework only accepts file handle or URI. With this new API, DRM session can start without waiting for the entire content. Changes are made by SEMC and Sony.
