For the allocator to create surfaces with the correct chroma an fourcc, it should use a surface format, not necessarily the negotiated format. Instead of the previous arbitrary extra formats list, the decoder extracts the valid pixel formats from the given VA config, and pass that list to the allocator which stores it (full transfer). Then, when the allocator allocates a new surface, it looks for a surface color format chroma-compatible with the negotiated image color format.
