} BUFFER;

chan channel number, 1 through maximum available channels based on the number of

boards detected, but no more than 64.

stream type of stream captured into buffer.

subtype stream subtype

buf pointer to buffer data.

length length of valid data currently in buffer, bytes.

frm frame number (H.264, JPEG streams).

pts time stamp (H.264, JPEG streams).

rsv Reserved.

S819_SUBTYPE provides additional information about the streams depending on stream's type.

For H.264 streams it is current slice type, for alarm stream it is alarm type. Application should first

determine the stream type using .stream, then use .subtype based on context.
