191
A conformant image processing stage for applying an effect to a YUV image or video. YUV_UV input and output are only currently handled using proprietary communication.
Port | Index | Notes
190 | `OMX_IndexParamPortDefinition` | Set this to control the input size of the image. Typically this is called by the component itself when this port is tunnelled with an appropriate output port. YUV420 packed planar and YUV422 packed planar image formats are supported. `nSliceHeight` must be a multiple of 16. `nStride` must be a multiple of 32 and equal to or larger than `nFrameWidth`. Port 190 also supports being connected to an output port of video domain, by setting the port definition type with a structure of `OMX_PortDomainVideo`.
191 | `OMX_IndexParamPortDefinition` | Query this to show what the output size will be. Set to alter the number of buffers to be used, or change the `nSliceHeight`. `nSliceHeight` must be a multiple of 16, including 0 which indicates no preference. Other parameters must be unchanged.
`OMX_IndexConfigCommonImageFilter` | Query / set the current image filter applied.
`OMX_IndexConfigCommonImageFilterParameters` | Query / set optional parameters for some image filters.
`OMX_IndexConfigCommonColorEnhancement` | Query / set the colour enhancement. This overwrites the U/V planes with a constant value, and is applied after any currently selected filter.
`OMX_IndexParamImagePoolDisplayFunction` | Used to set up proprietary communication with the next component.
190 191 | `OMX_IndexParamImagePortFormat` | Query / set the image port format used. Both ports support non-compressed images of a small number of image formats.
| `OMX_IndexParamImagePoolExternal` | Query / set the location of an externally allocated image pool to use for output frames. Defaults to NULL, causing the component to allocate a pool when active.
`OMX_IndexParamImagePoolSize` | Sets the size of the image pool to be allocated by the component. Defaults to the output port frame size.
