+In the past xbmc delivered its own ffmpeg source code with specific patches to
+address bugs found during the use of xbmc. For Helix the ffmpeg source code was
+removed, Helix uses a vanilla ffmpeg source tarball and applies this patchset
+on top of it.

+Subject: [PATCH 01/17] Support raw dvdsub palette as stored on normal dvd's
+
+This is how the palette is stored on dvd's. Currently
+only xbmc passes the palette information to libavcodec
+this way.

+Subject: [PATCH 17/17] mlpdec: support TrueHD streams with an Atmos substream
+
+The fourth substream is being discarded, since its not raw audio data,
+but an encoded Atmos stream which needs a specialized decoder.
+
+Fixes decoding of the true hd stream from Transformers\ -\ Age\ of\ Extinction\ 2014\ 1080P-003.mkv
