- Fix start and end of picture to support multiple layers. Start of picture is the first packet of the base layer, while end of picture is when the marker bit is set (last packet of the enhancement layers). - All "layers" (aka "frames") of a picture are pushed downstream in a single buffer when picture is complete. - Forgive SID=0 for enhancement layers (invalid, but Chrome and Firefox sends it) Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/773>
