A conformant image processing stage for resizing YUV420, RGB565 and RGBA32 images. Using proprietary communication other image formats can also be used as inputs. This component performs a resize, with the output size determined by the input size and a custom resize parameter or by directly setting the output port parameter. The input images can either be stripes or full frames, in general stripes are preferred for large images or for some image formats including RGB565. The input image can also be cropped prior to resizing. Output images can either be full frames or stripes, and may be a different colour format from the input image.
Port | Index | Notes
60 | `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. The stripe height must be 16, or the frame height rounded up to the next multiple of 16. YUV420 packed planar image format is supported with even image dimensions. RGB565 and RGBA32 formats are also supported, RGB565 input only supports 16 high striped input. Other internal formats such as YUV_UV are also handled when using prioritary communication on this port.
`OMX_IndexConfigCommonInputCrop` | Allows cropping at the input. Cropping can be changed at any time.
`OMX_IndexConfigBrcmUseProprietaryCallback` | Forces use of proprietary tunnelling between ports.
`OMX_IndexParamCameraPoolToEncoderFunction` | Used to set up proprietary communication with the previous component.
61 | `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 size of the output image if the custom resize setting is not being used. YUV image dimensions must be even. `nSliceHeight` must be a multiple of 16, or 0 which indicates no preference. `nStride` must be a multiple of 32, or a multiple of 64 for RGBA32 format.
`OMX_IndexParamResize` | As an alternative to setting the output size directly through the port definition, set this parameter to control how the resize operates.
60 61 | `OMX_IndexParamImagePortFormat` | Set / query the image port format used. These ports support RGB565, RGBA32 or YUV420 raw bitmap formats.
`OMX_IndexParamBrcmSupportsSlices` | Query the port for support of nSliceHeight=16.
