This minimum number will be known only when the sequence header is generated. So we used to allow STREAMON on the CAPTURE plane only after sequence header is generated and checked with the minimum buffer requirement. But this causes a problem that we call a vb2_buffer_done for the sequence header buffer before doing a STREAON on the CAPTURE plane. This used to still work fine until this patch was merged b3379c6201bb3555298cdbf0aa004af260f2a6a4. This problem should also come in earlier MFC firmware versions if the application calls STREAMON on CAPTURE with some delay after doing STREAMON on OUTPUT. So this patch keeps the header buffer until the other frame buffers are ready and dequeues it just before the first frame is ready.
