Ideally, we should use the prefilled values in VAEnc* structures (if it is
available) to fill up any PackedHeader attributes so that we don't accidentally
mess up with different values in both places. The same pattern we have used in
all encoder packed header generation.

Here, I would recommend you to use VAEncPictureParameterBufferJPEG's
component_id and quantiser_table_selector (which are prefilled by your patch)
for packed frame header generation later on.
