This component is for testing. It accepts input buffers and
immediately discards them, counting how many it receives.
| Port | Index | Notes | 
| 240 241 242 | OMX_IndexParamPortDefinition | Set the port format. | 
| OMX_IndexConfigBrcmPortStats | Returns statistics about the input ports. | 
| OMX_IndexConfigBrcmPortBufferStats | Returns statistics about buffers recently seen 
  at the input ports. | 
| OMX_IndexConfigRequestCallback | Query / set whether an OMX_EventParamOrConfigChanged event
  should be generated when parameters change state within the component.
  Currently supported for OMX_IndexConfigBrcmPortBufferStats. | 
| OMX_IndexParamBrcmCRC | Query for the latest CRC for input data on this port. | 
| 240 | OMX_IndexConfigVideoFramerate | Sets the expected framerate (16.16 format). If set, the component will assert if any
  frames arrive late (where "late" is one or more frame intervals later than expected). | 
| OMX_IndexParamBrcmMaxFrameSkips | Sets the maximum number of times we allow an image to arrive 'late' (see
  OMX_IndexConfigVideoFramerate). The default value is zero. | 
| OMX_IndexParamBrcmPixelAspectRatio | Sets the expected pixel aspect ratio (represented by the standard 
  OMX_CONFIG_POINTTYPE structure, nY must not be 0, use e.g. 0/1 to 
  represent 0 or unknown ratio.). If set, the component will assert if it receives 
  video frames that do not match the expected aspect ratio. | 
| OMX_IndexParamBrcmMaxCorruptMBs | Sets the maximum number of corrupt macroblocks allowed. The default value is zero. | 
| 240 241 | OMX_IndexParamCameraPoolToEncoderFunction | Used to set up proprietary communication with the previous component. | 
| OMX_IndexConfigBrcmUseProprietaryCallback | Forces use of proprietary tunnelling between ports. | 
|  | OMX_IndexParamBrcmThreadAffinity | Query / set which core this component should execute on. | 
| OMX_IndexParamBrcmCRCEnable | Query / set whether this component should calcualte CRCs on all input
  data received.  Setting this index resets CRCs on all ports to zero.
  CRC calculation defaults to off. |
