A conformant image encode component, which takes raw pixels on its
input port, and encodes the image into various compressed formats on
the output port.
| Port | Index | Notes
|
| 340 | OMX_IndexParamPortDefinition
| Query / set the port definition for the input port.
|
| OMX_IndexParamCameraStripeFunction
| Used to set up proprietary communication with the previous component.
|
| OMX_IndexConfigBrcmUseProprietaryCallback
| Forces use of proprietary tunnelling between ports.
|
| 341 | OMX_IndexParamPortDefinition
| Query / set the port definition for the output port.
The component supports format conversion for when the codec does not
support the input format. Where the codec supports multiple input
formats, the eColorFormat field can be used to specify which is to be
used. If set to OMX_COLOR_FormatUnused, the component will select a
default colour format to be used for the codec.
|
| OMX_IndexParamQFactor
| Query / set the quality factor for the encoded image. This is only
supported by the JPEG codec.
|
| OMX_IndexParamBrcmEnableIJGTableScaling
| Query / set whether we use standard IJG quality tables when using the
JPG encoder.
|
| OMX_IndexParamBrcmDisableEXIF
| Disables generation of EXIF tags.
|
| OMX_IndexParamBrcmThumbnail
| Sets the properties for the thumbnail generation. The component must
be in loaded state. Currently only the JPEG codec supports this and
only if EXIF generation is also enabled.
|
| OMX_IndexConfigMetadataItem
| Set metadata to be included in the output file. Currently only the
JPEG codec supports including metadata. The component must be in
loaded state. eScopeMode must be
OMX_MetadataScopePortLevel. nScopeSpecifier must be
30. eKeyCharset must be ASCII, Binary, or
unknown. nKey must start with "EXIF.",
"IFD0." or "GPS." and be a valid EXIF property allowed
within that table. Supported tags are listed in the component
documentation for the image_decode component.
Some exif tags may be added with image capture data from a directly
connected camera component if they have not already been set.

| 340 341 | OMX_IndexParamImagePortFormat
| Query / set the image port format.
