+                        The count of packets that must be decoded after this packet in order to refresh the decoder,
+                        if the packet is independently decodable.  This value should be ignored if
+                        ``mIsIndependentlyDecodable`` is 0.

+
+    @discussion
+        For independently decodable packets, the ``mPreRollCount`` indicates how many additional packets need
+        to be decoded after this packet in order for the decoder to start returning optimal output,
+        if this is the first packet decoded since the decoder was initialized.
+
+        For example, if this packet is packet #123 of some given packet stream, and ``mIsIndependentlyDecodable``
+        is 0, or ``mIsIndependentlyDecodable`` is 1 and ``mPreRollCount`` is non-zero, and the client desires optimal
+        output starting with the output corresponding with packet #123 (because for example the client
+        is an audio player whose user seeks to a starting playback position corresponding with packet #123),
+        the client would scan back, starting at packet #122, searching for an independently decodable
+        packet with a preroll not intersecting packet #123.  If for packet #122 ``mIsIndependentlyDecodable``
+        is 0, or ``mIsIndependentlyDecodable`` is 1 but ``mPreRollCount`` is 2 or more, the client would still not
+        get optimal output for packet #123 if starting here, so the client continues to scan back.
+        If for packet #121 ``mIsIndependentlyDecodable`` is 1 and ``mPreRollCount`` is 2 or less, the client would
+        start decoding from this point, but discard the output equivalent of the two extra input packets
+        (desired first output packet - actual first decoded packet, or 122 - 120 == 2).
