[FFmpeg-devel] [PATCH] avformat/wavdec: increase requested probe score for codec probe

Codec probing was primarily added to the wav demuxer to support DTS-in-wav
files, but DTS probing functions return AVPROBE_SCORE_EXTENSION+1, so we can be
a bit more strict with the required score.

This fixes MP3 misdetections for some wav files.

Fixes ticket #11581.
