pyv4l2.py code breaks big-endian platforms #25

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
The strings in the 'pixelformats' tuple are only valid for little-endian 
systems. The code should implement the same functionality as the C-macro 
used in the V4L2 headers:

#define v4l2_fourcc(a,b,c,d)\
    (((__u32)(a)<<0)|((__u32)(b)<<8)|((__u32)(c)<<16)|((__u32)
(d)<<24))

...
#define V4L2_PIX_FMT_RGB32   v4l2_fourcc('R','G','B','4') /* 32  
RGB-8-8-8-8   */
...
