If nPortIndex is OMX_ALL, it returns the sensor mode corresponding to nModeIndex, and the number of modes in nNumModes. If nModeIndex is greater than or equal to nNumModes only nNumModes is returned. If nPortIndex is equal to a camera video output port index, it returns the sensor mode that would be selected for the values currently in OMX_IndexParamPortDefinition for that port.

The src_rect indicates which area of the frame to display. If all values are zero, the whole frame will be used.

This config can be set multiple times, and will buffer up stepping requests until we have media requests to fulfil, or the clock is stopped or un-paused. This config can also be used on some video output ports and, if nU32 is non-zero, requests that the output port forwards the next nU32 frames appending an EOS marker on the last frame, and then ceases to forward data on this port. If nU32 is zero, any previous request to forward a limited number of frames is cancelled and the default behaviour of this port will resume.

This index uses the standard IL structure OMX_PARAM_MINALIGNTYPE Allows the component to be queried for the minimum alignment (in bytes) required on a port for a given color format. Used by the MMAL framework to allow a reduction in the padding.
Query for the number of output channels in the decoded streamOMX_IndexParamNumOutputChannelsUsed by: video_decode This index uses the standard IL structure OMX_PARAM_U32TYPE This indicates whether the stream is 2d (1 channel) or stereoscopic (2 channels).

This is to allow packing of values into fewer bits (eg 10 bit packed in the LSBs of a 16 bit word). Value is the number of bits to shift left. The range will vary based on output format.
Specifying maximum frame sizeOMX_IndexParamPortMaxFrameSizeUsed by: camera This index uses the standard IL structure OMX_FRAMESIZETYPE This control can be used to control the maximum frame size allowed on an output port.
This index uses the standard IL structure OMX_PARAM_U32TYPE This parameter uses internal configuration to determine used, so should not be changed without explicit internal knowledge.
This index uses the standard IL structure OMX_CONFIG_PORTBOOLEANTYPE Queries whether the component can remove all padding from images, or can accept images with no padding. Used by the MMAL framework predominantly. Superceded by OMX_IndexParamMinimumAlignment.

} OMX_PARAM_RESIZETYPE;The mode determines the kind of resize. OMX_RESIZE_BOX allow the nMaxWidth and nMaxHeight to set a bounding box into which the output must fit. OMX_RESIZE_BYTES allows nMaxBytes to set the maximum number of bytes into which the full output frame must fit. Two flags aid the setting of the output size. bPreseveAspectRatio sets whether the resize should preserve the aspect ratio of the incoming image. bAllowUpscaling sets whether the resize is allowed to increase the size of the output image compared to the size of the input image.

OMX_U32 nFrameCount;
OMX_U32 xFrameRate;
} OMX_PARAM_SOURCETYPE;The source type determines the kind of image that is produced. Not all combinations of source type and image type are supported. The OMX_SOURCE_SWIRLY setting can only be used with YUV420 packed planar image formats. When producing RGB565 image format, the OMX_SOURCE_DIAGONAL and OMX_SOURCE_RANDOM modes are treated as OMX_SOURCE_NOISE. The nParam field is used to specify the colour for the source colour mode, and the offset of the diagonal pattern for diagonal mode. For the blocks mode, nParam is used as the seed for the random colour generator. The nFrameCount parameter determines how many frames to send. If it is zero, then frames are sent continuously. For any other value, it counts down until it has sent that many frames, and then stops, sending out an EOS. The xFrameRate setting is used to determine the timestamp for each frame produced, or can be set to zero if timestamps should all remain at zero.
