gstreamer omxh264encoder error

[Andrea]

The addresses of the buffers are "fixed", when I get all the information
(vidioc_s_fmt) I allocate 8 "frames" in memory and they are no longer
modified. These buffers are passed to gstreamer (userspace) via the mmap
function:

        long length = vma->vm_end - vma->vm_start;

	if( length > PAGE_ALIGN(skel->pix_format.sizeimage) ){
		printk(KERN_INFO "ERROR, length (%d) > skel->buffer_size (%d)", length,
skel->buffer_size);
		return -EINVAL;
	}

	vma->vm_page_prot = pgprot_noncached(vma->vm_page_prot);
	vma->vm_flags |= VM_IO;
	int ret = remap_pfn_range(vma, vma->vm_start,
PFN_DOWN(virt_to_phys(phys_to_virt(lp->paddrY[mmap_idx]))) + vma->vm_pgoff,
length, vma->vm_page_prot);	

	skel->buffers[mmap_idx].buffer.flags |= V4L2_BUF_FLAG_MAPPED;

	if( mmap_idx < MAX_FRAMES-1 )
		mmap_idx++;
	else
		mmap_idx = 0;

	return ret;


The addresses used for the 8 frames stored in memory, not remapped to
userspace by mmap:
Buf 0: 0xe000000
Buf 1: 0xe400000
Buf 2: 0xe800000
Buf 3: 0xec00000
Buf 4: 0xf000000
Buf 5: 0xf400000
Buf 6: 0xf800000
Buf 7: 0xfc00000
