Hello, we would like to ask for suggestions for new fourcc formats for multiplanar buffers.
There are planar formats in V4L2 API, but for all of them, each plane X "immediately follows Y plane in memory". We are in the process of testing formats and V4L2 extensions that relax those requirements and allow each plane to reside in a separate area of memory. I am not sure how we should name those formats though. In our example, we are focusing on the following formats at the moment: - YCbCr 422 2-planar (multiplanar version of V4L2_PIX_FMT_NV16) - YCbCr 422 3-planar (multiplanar version of V4L2_PIX_FMT_YUV422P) - YCbCr 420 2-planar (multiplanar version of V4L2_PIX_FMT_NV12) - YCbCr 420 3-planar (multiplanar version of V4L2_PIX_FMT_YUV420) Could anyone give any suggestions how we should name such formats and what to pass to the v4l2_fourcc() macro?
