Thanks for your answer
It seems that what you are talking about is the case of a slice encoder, where the user side would generate the header/metadata.
In our case the HW is not a slice encoder, as it also generates the header/metadata, but it can generate it in some separate buffer, and this is required in some use-cases.

So I don’t think there is a lot of specification work needed . We just need a way to output several buffers instead of one, and to specify which one is the header buffer, and which one contains slice data.
