           Summary: sws_scale() 2nd argument type mismatch

gstffmpegscale.c: In function 'gst_ffmpegscale_transform':
gstffmpegscale.c:677: error: passing argument 2 of 'sws_scale' from
incompatible pointer type
f:/gstreamer-buildslave/msys/1.0.11/local/include/libswscale/swscale.h:187:
note: expected 'uint8_t **' but argument is of type 'const guint8 **'

1)
swscale.h says:
int sws_scale(struct SwsContext *context, uint8_t* srcSlice[], int srcStride[],
int srcSliceY, int srcSliceH, uint8_t* dst[], int dstStride[]);

2)
glibconfig.h says:
typedef unsigned char guint8;

3)
gstffmpegscale.c says:
sws_scale (scale->ctx, (const guint8 **) in_data, scale->in_stride, 0,
scale->in_height, out_data, scale->out_stride);

The (3) is caused by
http://cgit.freedesktop.org/gstreamer/gst-ffmpeg/commit/?id=0b40ac6331fece58617dbfaadb1460a93d38dad4

Everything worked before (3)

How to fix:
Supply in_data as (uint_8**) rather than (const guin8 **), because GCC thinks
that sws_scale expects (uint8_t**).
