304	"wrong detection: ""Format mp3 detected only with small score of 1"""	AndreAdrian		"The IP camera Lumenera Le165 uses MJEPG video codec. If ffmpeg version 0.7.1 is used together with OpenCV version 2.3.0 the Le165 mjpeg codec is miss-detected as mp3 codec. A simple fix (work around) is possible.

change from
        if (probe_size < offset) {
            continue;
        }
to 
        if (probe_size < offset) continue; 
        if (score <= 1) continue;

Justification: With a low score of 1 the mp3 codec is now ignored. OpenCV and ffmpeg find now the correct codec.
Disadvantage: Cases where codec was correct with score == 1 are now broken. "	defect	closed	normal	avformat	0.7.1	needs_more_info	mp3 mjpeg misdetection				0	0
