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. 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 100x'. Use -S- for
|
|
no SEEKTABLE. Note: '-S #x' 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>

which is the default. 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.</para>
