-Subject: [PATCH] media: v4l: Add definitions for HEVC stateless
- decoding
-
-This introduces the required definitions for HEVC decoding support with
-stateless VPUs. The controls associated to the HEVC slice format provide
-the required meta-data for decoding slices extracted from the bitstream.
-
-They are not exported to the public V4L2 API since reworking this API
-will likely be needed for covering various use-cases and new hardware.
-
-Multi-slice decoding is exposed as a valid decoding mode to match current
-H.264 support but it is not yet implemented.
-
-The interface comes with the following limitations:
-* No custom quantization matrices (scaling lists);
-* Support for a single temporal layer only;
-* No slice entry point offsets support;
-* No conformance window support;
-* No VUI parameters support;
-* No support for SPS extensions: range, multilayer, 3d, scc, 4 bits;
-* No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.
