This function takes two inputs -
| width | is the input picture width | |
| omx_pxlfmt | is the input openmax standard pixel format It calculates the byte per pixel needed to display the picture with the input omx_pxlfmt The output stride for display is thus product of input width and byte per pixel |

FIXME: Configuration values should be clamped to prevent memory trampling and potential segfaults. It might be best to store clamped AND unclamped values on a per-port basis so that OMX_GetConfig can still return the unclamped ones.

OpenMAX IL spec says chroma channels are subsampled by 4x horizontally AND vertically in YUV 4:1:1. Conventional wisdom (wiki) tells us that it is only subsampled horizontally. Following OpenMAX spec anyway. Technically I guess this would be YUV 4:1:0.
