Attach element-specific parameters to meta

elements which may handle this ROI.

The name of s

is used to identify the element these parameters are meant for.
|
|
Packit |
971217 |
This is typically used to tell encoders how they should encode this specific region.
|
|
Packit |
971217 |
For example, a structure named "roi/x264enc" could be used to give the
|
|
Packit |
971217 |
QP offsets this encoder should use when encoding the region described in meta
|
|
Packit |
971217 |
.
|
|
Packit |
971217 |
Multiple parameters can be defined for the same meta so different encoders
|
|
Packit |
971217 |
can be supported by cross platform applications).
