Cong Zhong 46c01de05d codecparsers: mpeg2: store quantization matrices in zigzag scan order. ... Quantizer matrices are encoded in zigzag scan order in the bitstream, but they are stored in raster scan order when they are parsed. However, default matrices were also prepared in zigzag scan order, hence the mismatch. i.e. the matrices were presented either in raster scan order if they are explicitly present in the bitstream, or they were presented in zigzag scan order if the default definitions were to be used instead. One way to solve this problem is to always expose the quantization matrices in zigzag scan order, since this is the role of the parser to not build up stories from the source bitstream and just present what is in there. Utility functions will be provided to convert quantization matrices in either scan order. https://bugzilla.gnome.org/show_bug.cgi?id=693000 Signed-off-by: Cong Zhong <congx.zhong@intel.com> Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>		2013-02-06 14:22:41 +01:00
