We could throw many more into the thread. When comparing video encodings, we must take into account: - speed of encoding (many of the encoders are not fast enough for real time, they may decode fast, but we need fast encoding too) - quality (and how to measure it - see http://x264dev.multimedia.

Hello, all. This isn't a critical question so please do not take lots of time to answer it unless it would be a helpful general discussion. We are still trying to properly set our expectations about video streaming using SPICE on low bandwidth networks. Indeed, this is our principle interest in S
