Were you able to get sequential JPEG to work? I have been unable to JPEG
encode an image at 5MP - I simply run out of memory.
I have been able to convert a 5MP image from bayer to YUV using the IPIPE.
This is the routine I use to set the structure before I call the ioctls:
setparms(&pIpipeParam, width, height);
ret = ioctl(fd_ipipe, IPIPE_SET_PARAM,pIpipeParam);
if (ret < 0) {
printf("IPIPE_SET_PARAM fail\n");
return 0;
}
/* There is a note that I read somewhere that suggested there was
supposed to be a delay between the SET_PARAM and the START ioctls, but I
can't find any example
* code that tells me what that delay should be.... or why there needs to
be one.
*/
if ((ret = ioctl(fd_ipipe, IPIPE_START, &convert)) < 0){
printf("IPIPE_START fail in IPIPE_process ret = %d\n", ret);
return 0;
}
This sets the structures:
/*
* Set some standard parameters for the IPIPE
* This process needs to know the width & height
*/
static void setparms(struct ipipe_params *pIpipeParam, int width, int
height) {
/* Setting up the ipipe for images less than 1344 pixels is fairly straight
* forward. This routine detects images larger than that boundary and splits
* the processed width by 1/2.
*/
pIpipeParam->ipipeif_param.hnum = width;
pIpipeParam->ipipeif_param.vnum = height;
pIpipeParam->ipipeif_param.glob_hor_size = width + 8;
pIpipeParam->ipipeif_param.glob_ver_size = height + 10;
