Hi Hans,
I found struct media_pipeline actually is completely empty and I assume
we use that to control all the entities belonging to one media_pipeline.
media_pipeline should contains either all the media_link or all the
media_entity. How come an empty struct can provide those information?
What about following ideas?
1. when media_entity_create_links, it will return a media_link pointer.
2. we save this media_link pointer into the media_pipeline
3. use this media_pipeline for start streaming, stop streaming and
validate links.
Maybe I miss something during recent media controller changes.
Thanks,
-Bryan
