I just understand that at
NSTUB( 0x37304, vram_info )
we have got a table with 3 records, with structure is 'struct vram_info'
struct vram_info
{
uint8_t * vram; // off 0x00
uint32_t width; // maybe off 0x04
uint32_t pitch; // maybe off 0x08
uint32_t height; // off 0x0c
uint32_t vram_number; // off 0x10
};
see
https://bitbucket.org/hudson/magic-lantern/src/7c9dc58abd31/vram.hfound by Trammel months ago.
so the 3 YUV buffer addresses, size and pitch should be there..
this is confirmed with 550d 1.0.9 and 0x40D07800 / 4c233800 / 4f11d800
