Sometimes the value coded in the Stored Height field of the Video descriptor is the Field height and sometimes it is the Frame height. How to solve this ambiguity ? The same is the case with Sample rate. Sometimes it is the field rate and sometimes frame rate. |

The value depends on FrameLayout as follows: FULL_FRAME = frame height SEPARATE_FIELDS = field height SINGLE_FIELD = field height MIXED_FIELDS = frame height SEGMENTED_FRAME = frame height |

Thanks for the reply Matt. Can I assume the same with the sample rate ? FULL_FRAME = frame rate SEPARATE_FIELDS = field rate SINGLE_FIELD = field rate MIXED_FIELDS = frame rate SEGMENTED_FRAME = frame rate |

That sounds about right - although I would be tempted to use frame rate for SINGLE_FIELD as this is basically the rate at which the data we are receiving was captured. |
