At check_count == CHECK_COUNT the existing branch caps the score at SCORE_MAX/2 even when every analyzed packet is sync-aligned and when analyze() already has full confidence. This loses probe to signature-only image demuxers (e.g. png_pipe at SCORE_MAX - 1) for streams with a small leading non-TS prefix. Some CDNs prepend a 1x1 PNG to MPEG-TS payloads to bypass image-only Content-Type filtering, and the PNG signature otherwise wins the first probe iteration.
