Some decoders use intra slice/frame references. The capture buffer
pointed by these references might be new and thus have invalid
timestamp which prevents the decoder logic from retrieving the
vb2_buffer object based on the output buf timestamp.
Copy all metadata (including the timestamp) before starting the decode
operation.
