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.
