@davidplowman, this is going to need a "Signed-off-by:" tag in the commit message. |
Since the unicam driver was modified to write to a dummy buffer when no user-supplied buffer is available, it can now write to and return a buffer even when there's only a single one. Enable this by changing the min_buffers_needed in the vb2_queue; it will be useful for enabling still captures without allocating more memory than absolutely necessary.
