Subject: [PATCH 4/5] visl: Add a codec specific variability parameter
|
|
|
|
When running tests with different input data, the stable output frames
|
|
could be too similar and hide possible issues.
|
|
|
|
This commit adds variation by using some codec specific parameters.
|
|
|
|
Only HEVC and H.264 support this.
