The AVIStreamRelease macro determines the size of the buffer needed to store one sample of information from a stream. The size corresponds to the sample at the position specified by lPos.
AVIStreamSampleSize( pavi, lPos, plSize );
Handle to an open stream.
Position of a sample in the stream.
Address to contain the buffer size.
Returns zero if successful or an error otherwise. Possible error values include the following:
|AVIERR_BUFFERTOOSMALL||The buffer size was smaller than a single sample of data.|
|AVIERR_MEMORY||There was not enough memory to complete the read operation.|
|AVIERR_FILEREAD||A disk error occurred while reading the file.|
The AVIStreamSampleSize macro is defined as follows:
#define AVIStreamSampleSize(pavi, lPos, plSize) \ AVIStreamRead(pavi, lPos, 1, NULL, 0, plSize, NULL)
