OMX.broadcom.source
A conformant image source for creating raw bitmap images. The single
output port can be configured with the output size, as well as details
of how to generate the image.
| Port | Index | Notes
| | 20 | OMX_IndexParamPortDefinition
| Set this to specify the output format. Colour format should be
RGB565, RGB888, ABGR8888, YUV420 packed planar, or YUV422 packed
planar. Specify nSliceHeight as 16 or leave as zero (and it
will use 16 internally). Alternatively to produce full frames set
nSliceHeight to the frame size rounded up to the next multiple
of 16. Specify nStride as a multiple of 32, or 64 for
ABGR8888, or 16 for RGB888, or leave as zero (and it will assign a
suitable value internally).
| | OMX_IndexParamImagePortFormat
| Query / set the image port format used. The output port
supports non-compressed images of a small number of image formats.
| | OMX_IndexParamSource
| Set this to configure how the output image will be created.
| | OMX_IndexParamSourceSeed
| Set this to control the seed of any random image created.
| | OMX_IndexConfigBrcmPortStats
| The output port can be queried for the number of frames, buffers, and
bytes produced.
