How to figure out buffer's parent GESClipAsset with GESPipeline?

[Thibault Saunier]

Hi,

Do you need mixing? If you don't using a GstMeta might be straight
forward, just create an effect element to add metas on buffers and add
it as a effect on all GESClips (not sure how you could handle gaps...
but do you care?)

If you need mixing, I think theorically we could add an "aggregate"
TransformFunction type for metas and then we could have GstAggregator
use that to be able to get upstream "asset metas" as a  list of metas
from the input buffers to the outputed buffers.

Hope it helps,

Thibault
