Well, actually setting this caps in appsink:

"video/x-raw,format=(string)I420"

leaves the buffer writable (33 calls to meta_transform, all ok) while
most of the others (tried many, not all) don't (last 7 calls not writable).

This tells me that videoconvert is keeping a reference. Removing
videconvert obviously solves my problem (but it is not an option).

Thanks,
