Update ffmpeg: flac decoding bug

FFMPEG can sometimes have issues fast seeking through files. It can find false frames.

For example: https://api.acousticobservatory.org/audio_recordings/1111135/media.wav?start_offset=2753.5&end_offset=2763.5 tiggers the bug. Actual server side command below:

        Standard output:

Notes:

full file decode with ffmpeg works
full file decode with flac -d works
cutting the segment with flac -d --skip 45:53.500 --until 45:63.500 -o test2.wav works.

This looks like it is a ffmpeg bug?
