Some well known decoder wrongly set num_planes to 0 in their format instead of
one. In this case we would endup with no size when deciding buffer allocation.
/* figure out the frame layout */
v4l2object->n_v4l2_planes = MAX (1, format->fmt.pix_mp.num_planes);
v4l2object->sizeimage = 0;
- for (i = 0; i < format->fmt.pix_mp.num_planes; i++) {
+ for (i = 0; i < v4l2object->n_v4l2_planes; i++) {
v4l2object->bytesperline[i] =
format->fmt.pix_mp.plane_fmt[i].bytesperline;
v4l2object->sizeimage += format->fmt.pix_mp.plane_fmt[i].sizeimage;
