[FFmpeg-devel] [PATCH] avformat/srtdec: give WebVTT priority

[wm4]

WevVTT and SRT can look very similar. For some samples, they both
succeed and return AVPROBE_SCORE_MAX, which leads to probing failure.

This gives priority to WebVTT in ambiguous cases. Since WebVTT only
succeeds if the header is present, it's pretty sure WebVTT should win in
these cases.
