flac.sgml

这是著名的TCPMP播放器在WINDWOWS,和WINCE下编译通过的源程序.笔者对其中的LIBMAD库做了针对ARM MPU的优化. 并增加了词幕功能.

		<listitem>
		  <para>
		    Include a point or points in a SEEKTABLE.  Using #,
		    a seek point at that sample number is added.  Using
		    X, a placeholder point is added at the end of a the
		    table.  Using #x, # evenly spaced seek points will
		    be added, the first being at sample 0.  Using #s, a
		    seekpoint will be added every # seconds (# does not
		    have to be a whole number; it can be, for example, 9.5,
		    meaning a seekpoint every 9.5 seconds).  You may use
		    many -S options; the resulting SEEKTABLE will be the
		    unique-ified union of all such values.  With no -S
		    options, flac defaults to '-S 10s'.  Use --no-seektable
		    for no SEEKTABLE.  Note: '-S #x' and '-S #s' will not
		    work if the encoder can't determine the input size before
		    starting.  Note: if you use '-S #' and # is >=
		    samples in the input, there will be either no seek
		    point entered (if the input size is determinable
		    before encoding starts) or a placeholder point (if
		    input size is not determinable).</para>

		<listitem>
		  <para>Tell the encoder to write a PADDING metadata
		    block of the given length (in bytes) after the
		    STREAMINFO block.  This is useful if you plan to
		    tag the file later with an APPLICATION block;
		    instead of having to rewrite the entire file later
		    just to insert your block, you can write directly
		    over the PADDING block.  Note that the total length
		    of the PADDING block will be 4 bytes longer than
		    the length given because of the 4 metadata block
		    header bytes.  You can force no PADDING block at
		    all to be written with --no-padding.  The encoder
		    writes a PADDING block of 4096 bytes by default.
