This will forward the query allocation when received between the connected listeners and aggregates the results of each listeners. This helps to indicate the upstream elements which metas are supported. For example it avoids v4l2src buffer copy when the downstream elements doesn't report that video meta is supported and the pitch is different than width.

Why has this pull request not being accepted? Is there a reason why the interpipe should not handle the allocation query in this way? The behaviour is the same as gsttee.c, which makes sense to me, but maybe I am missing something... |
