OMX.broadcom.image_encode

340
image_encode
341

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.

PortIndexNotes
340OMX_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.
341OMX_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.
