GStreamer calls the pitch a stride, and it's in bytes. It's not
specific using caps, but by adding GstVideoMeta. See function
gst_buffer_add_video_meta_full (). Be aware that offset is from a
GstBuffer perspective, if you have multiple GstMemory object, you need
to include the side of the previous GstMemory as needed.
