Description D.S. (Spider) Ljungmark 2012-07-12 15:31:41 UTC
I have a flac file that checks out as valid with "flac -t" and plays in mplayer (ffmpeg / libavcodec audio decoder)  without issue, but that fails in gstreamer flac decoders.

This happens both on 0.10.x git head ( jhbuild ) and released ( Fedora 17 current )

The error is around 2 minutes into the song:

    flacparse: avoid some more frame misparsing by additional header sanity check
    ... using a required constant blocking_strategy bit.
