Glenn Maynard 00f371fa7c remove IsStreamingFromDisk 2006-12-23 07:15:32 +00:00
Glenn Maynard ce3ba75e23 errors in source filters, so each filter in the chain doesn't have a separate 
error

not 1 or 2 anymore; RageSound only supports 1 or 2 but intermediate
filters may have more

Glenn Maynard 7385c1f4c1 merge SetPosition_Accurate and SetPosition_Fast. Use a property 
instead.

Glenn Maynard 0b529a4960 RageSoundReader::Read() returns sound data which may be at a 
different rate than the source it's reading from; one second
of returned data may correspond to two seconds in the source
material.

GetStreamToSourceRatio returns the ratio of returned data in
the next Read() call to source data.  This is propagated
upwards in the filter tree, so rate changes by a speed changer
in the middle of the tree will be reflected in the final
GetStreamToSourceRatio().

This means that whenever the ratio changes, Read() stops
returning data; it returns whatever it has, so the caller
has an opportunity to call GetStreamToSourceRatio again
and notice the change.

These semantics can be annoying to implement in some
cases, where only the processing of Read() may notice
a ratio change.  Read() may want to return 0, to say
"something changed, call GetStreamToSourceRatio again",
but 0 means EOF.

Add RageSoundReader::END_OF_FILE.  0 is now no
longer a special case; it means "there's more data, I
just didn't return any this time".  This is functionally
equivalent to errno EINTR.
