syncpoint is 16 bytes:
8 startcode + 1 forward_ptr + 1 timestamp + 1 back_ptr + 4
checksum + 1 frame_code
+End of Relevance
+EOR is a flag that can be attributed to a frame in any
stream, and marks
+the end of relavence of a stream on presentation, such as a
subtitle
+stream currently showing no subtitles on screen. EOR flag
can only be
+given to zero byte frames, and must be set as keyframe as
well. Once EOR
+is seen on such a stream, the stream is set EOR until the
next keyframe on
+that stream. Streams which are set EOR are ignored by
back_ptr in
+syncpoints until EOR is unset. The significance of EOR is
to set the
+stream as irrelevant when seeking and searching for optimal
keyframes to
+begin demuxing.
+
Error Checking
There are several ways to detect a damaged stream in NUT
during demuxing:
