ffmpeg: Check read_ffserver_streams() return value The function avformat_alloc_context() will return a NULL pointer on failure. However, in function read_ffserver_streams(), its return value is not validated and the subsequent dereference may result in a bad memory access bug. Check its return value against NULL and avoid potential NULL dereference.
