|
||
|
||
- Update to release 1.6.0
|
||
* Improved the tradeoffs for the random access mode across
|
||
presets M1-M13:
|
||
* Speeding up the higher quality presets by 30-40%
|
||
* Improving the BD-rate by 1-4% for the faster presets
|
||
* Improved the tradeoffs for the low delay mode for both screen
|
||
content and non-screen content encoding modes

|
||
input of the pipeline allowing the low delay mode to operate
|
||
at sub-frame processing latencies

|
||
offsets for a region of interest per frame

|
||
|
||
- Disable forced realtime scheduler priority
|
||
By default, the encoder library will attempt to set realtime
|
||
scheduler priority. Disable this behavior, as it serves no
|
||
practical purpose (video encoding does not benefit from reduced
|
||
process latency) and will only make the system unresponsive.
|
||
(Additionally, it is arguably not a video encoder library’s job
|
||
to manage scheduler priorities for the calling process.)
