| typedef enum OMX_VIDEO_CODINGTYPE | OMX_VIDEO_CODINGTYPE |
Enumeration used to define the possible video compression codings. NOTE: This essentially refers to file extensions. If the coding is being used to specify the ENCODE type, then additional work must be done to configure the exact flavor of the compression to be used. For decode cases where the user application can not differentiate between MPEG-4 and H.264 bit streams, it is up to the codec to handle this.
| typedef struct OMX_VIDEO_PORTDEFINITIONTYPE | OMX_VIDEO_PORTDEFINITIONTYPE |
Data structure used to define a video path. The number of Video paths for input and output will vary by type of the Video component.
Input (aka Source) : zero Inputs, one Output, Splitter : one Input, 2 or more Outputs, Processing Element : one Input, one output, Mixer : 2 or more inputs, one output, Output (aka Sink) : one Input, zero outputs.
The PortDefinition structure is used to define all of the parameters necessary for the compliant component to setup an input or an output video path. If additional vendor specific data is required, it should be transmitted to the component using the CustomCommand function. Compliant components will prepopulate this structure with optimal values during the GetDefaultInitParams command.
