Another case for v4l2_m2m_buf_copy_metadata? As you know early the dst_buf, you
could do that once before you start the encoding, this could possibly remove the
duplication.

This is another process flow. if encoding successes, the irq function
would copy timestamp, otherwise the timeout function would handle it.
