| Subject: [PATCH] media: uapi: Add hevc ctrls for WPP decoding |
| |
| WPP can allow greater parallelism within the decode, but needs |
| offset information to be passed in. |
| |
| Adds num_entry_point_offsets and entry_point_offset_minus1 to |
| v4l2_ctrl_hevc_slice_params. |
| |
| This is based on Jernej Skrabec's patches for cedrus which |
| implement the same feature. |
