Subject: [PATCH] media: uapi: hevc: Add segment address field
|
|
|
|
From https://patchwork.linuxtv.org/patch/60725/
|
|
Changes requested, but mainly docs.
|
|
|
|
If HEVC frame consists of multiple slices, segment address has to be
|
|
known in order to properly decode it.
|
|
|
|
Add segment address field to slice parameters.
