sampleSize(at:)
Returns the size of a sample in bytes.
Declaration
func sampleSize(at sampleIndex: Int) -> IntParameters
- sampleIndex:
The index of the sample to query.
Return Value
The size of the sample.
Discussion
If you specify a sample index that isn’t in the range, the system returns 0. It also returns 0 if the sample buffer contains no sizes, which occurs if the samples in the buffer are noncontiguous, such as noninterleaved audio, or if the sample buffer contains a CVImageBuffer.
