            /A@@spark||/B@@spark-mini||/C@@vp6-hd||/D@@vp6||/E@@h264
            Not everybody can decode HD, not everybody has a 80x60 screen,
            H264/MP4 is buggy , so i choose VP6 as the highest priority

            Ideally, VLC would propose the different streams available, codecs
            and resolutions (the resolutions are part of the URL)

            For now we just built a list of preferred codecs : lowest value
            means highest priority
