DESCRIPTION
|
Mfs services a volume for playing media files. By default, it
provides a service to reproduce MPEG 2 Layer 3 files. Using it
together with speaksrvstd to provide a speech service is also
common. It listens for 9P clients at the network address tcp!*!audio
by default. Flags –abcAD and options –Vsmn are like those in
most file servers and are described in planbfs(4). The player command used to decode the media file is by default mpeg3play – and receives the MPEG file through stdin. This can be changed using option –p. Most notably, the voice volume relies on this option to wrap speech programs. This is done by using speaksrvstd as the underlying program. This program delivers the text given as arguments to a remote speech utility (Festival for Linux, in the version distributed for this program). Before delivering the text, the filter spellwords is applied to the text, if such filter exists. This is useful to translate the text to a more appropriate format for speech, e.g., replace planb with plan b and other similar rewrites. If option –w is supplied to mfs, each write pipes to a different instance of the underlying program. Option –d enables debug messages, and –D enables even more debugging. Option –v enables a volume control file.
The volume announces itself as /devs/audio unless a different
name is given with the –V option. |
