media_entity_pipeline_start — Mark a pipeline as streaming
int media_entity_pipeline_start ( | struct media_entity * entity, |
struct media_pipeline * pipe); |
Mark all entities connected to a given entity through enabled links, either directly or indirectly, as streaming. The given pipeline object is assigned to every entity in the pipeline and stored in the media_entity pipe field.
Calls to this function can be nested, in which case the same number of
media_entity_pipeline_stop calls will be required to stop streaming. The
pipeline pointer must be identical for all nested calls to
media_entity_pipeline_start.
