[FFmpeg-devel] [PATCH] Update for Chromaprint 1.4

[Georgi D. Sotirov]

Hello FFmpeg community,

In new Chromaprint 1.4 (that was released 2016-12-03) type 
ChromaprintContext is no longer void *, but empty structure (see commit 
2132e19 [1] from 2016-06-06 in BitBucket). This breaks compilation of 
libavformat/chromaprint.c, because member ctx of ChromaprintMuxContext 
should be pointer. This simple change resolves the problem.

  static void cleanup(ChromaprintMuxContext *cpr)

I hope you apply the patch.
