-Subject: [PATCH] staging: bcm2835-codec: implement
- V4L2_CID_MIN_BUFFERS_FOR_CAPTURE
-
-The stateful decoder specification shows an optional step for retrieving
-the miminum number of capture buffers required for the decoder to
-proceed. While not a required parameter, having it makes some
-applications happy.
-
-bcm2835-codec is a little different from other decoder implementations
-in that there is an intermediate format conversion between the hardware
-and V4L2 buffers. The number of capture buffers required is therefore
-independent of the stream and DPB etc.
-
-There are plans to remove the conversion, but it requires a fair amount
-of rework within the firmware. Until that is done, simply return a value
-of 1.
