demux, command: export bof/eof flags

Browse Source

``bof-cached`` indicates whether the seek range with the lowest timestamp
points to the beginning of the stream (BOF). This implies you cannot seek
before this position at all. ``eof-cached`` indicates whether the seek range
with the highest timestamp points to the end of the stream (EOF). If both
``bof-cached`` and ``eof-cached`` are set to ``yes``, the entire stream is
cached.
``fw-bytes`` is the number of bytes of packets buffered in the range ``fw-bytes`` is the number of bytes of packets buffered in the range
