Free vorbis decoder software for linux

MMS Decoder provides a script for sending MMS messages to a Web page.
MMS Decoder can receive MMS messages, decode them, and display them on a Web page. This is done by acting as an MMSC, which is a server to which MMS messages are sent.
The only requirement to get this to work is an internet connected webserver, with PHP support and a phone which can send MMS (some operators may have blocked all MMS servers except their own, and the application will not work with these).
When an MMS is sent, its usually sent to the operators MMSC, which notifies the reciever (by a binary encoded SMS) that she or he has an MMS to retrieve, then his or her phone connects to the MMSC server and fetches the MMS which has been made available on the server via HTTP. What my web application actually do is to pretend to be an MMSC, recieves the MMS, decodes it (its encoded as specified in the WAP-209-MMSEncapsulation-20020105-a and wap-230-wsp-20010705-a specifications) and then stores it.
The only thing you need to do to make this work on your phone, is to set the phones MMSC (may also be labeled Service Center, MMS Center, or MMS Server) to http://domain.com/mms/get.php, or something like that, and then start sending MMS messages. And best of all, it will not cost you like 20 cents which the phone operators charge, the only cost is what your operator charge for WAP access (usually a lot less than the MMS cost), since the MMS is sent over WAP.
MMS Decoder was first written as a school project, and therefore Ive written a very detailed report of the decoding mechanism. This is, how ever, written in swedish so it would not be useful to anyone who doesnt know swedish. You can grab the report here.
Enhancements:
- An installation script, which creates the database or/and the tables, was added.
- A phpMyAdmin dump of the database structure was added.
- The directory structure of the package was changed.

Ogg::Vorbis::Header is an object-oriented interface to Ogg Vorbis information and comment fields.

SYNOPSIS

use Ogg::Vorbis::Header;
my $ogg = Ogg::Vorbis::Header->new("song.ogg");
while (my ($k, $v) = each %{$ogg->info}) {
print "$k: $vn";
}
foreach my $com ($ogg->comment_tags) {
print "$com: $_n" foreach $ogg->comment($com);
}
$ogg->add_comments("good", "no", "ok", "yes");
$ogg->delete_comment("ok");
$ogg->write_vorbis;

This module presents an object-oriented interface to Ogg Vorbis files which allows user to view Vorbis info and comments and to modify or add comments.

CONSTRUCTORS

new ($filename)

Partially opens an Ogg Vorbis file to ensure it exists and is actually a Vorbis stream. It then closes the filehandle. It does not fill in the objects data fields. These fields will be automatically filled the first time they are accessed using the objects instance methods. Returns undef if there is a problem opening the file or the file is not valid Ogg Vorbis.

load ([$filename])

Opens an Ogg Vorbis file, reads its information, and then closes the filehandle. Returns undef if there is a problem opening the file or the file is not valid Ogg Vorbis. This is both a constructor and an instance method. The filename is required in constructor context, but should be left out when you call this as an instance method on an object. When called as an instance method, it (re)loads the info and comment data from the file. This can be used to reset the state of the object if write_vorbis hasnt been called. Note that the path parameter is ignored in instance context.

INSTANCE METHODS

These methods may be called on actual Header objects, using the -> operator or indirect objects as you prefer.

info ([$key])

Returns a reference to a hash containing format information about the Vorbis file. Hash fields are: version, channels, rate, bitrate_upper, bitrate_nominal, bitrate_lower, and bitrate_window, length. The bitrate_window value is currently unused by the vorbis codec. You can modify the referenced hash if you want, but I wouldnt suggest it.

The optional key parameter allows you to extract a single value from the internal hash (passed by value, not reference). If the key is invalid, undef is returned.

comment_tags ()

Returns an array holding the key values of each comment field. You can then use these values to access specific fields using comment. This may seem somewhat clunky at first but it will speed up most programs. In addition, it makes it easier to support the Ogg Vorbis comment standard which allows multiple fields with the same key.

comment ($key)

Returns a list of comments given a key. If the key does not exist, returns undef.

add_comments ($key, $value, [$key, $value, ...])

Adds comments with the given keys and values. Takes an array of alternating keys and values as parameters. Keys and values should be valid ascii in the range 0x20 - 0x7D and the key should exclude 0x3D (=). This is a subset of the Vorbis standard which allows this range for the key field and all of utf8 for the value field. This will be fixed in future a release.

If an odd-length array is passed in the routine will fail and return undef. Key and value will be trimmed of characters which do not match the format requirement.

edit_comment ($key, $value, [$num])

Edits a given comment field. The optional num field is used to differentiate between two comments with the same key. If no num is supplied, the first value--as reported by comment--is modified. If the key or num are invalid, nothing is done and undef is returned. If all goes well, the old value is returned.

delete_comment ($key, [$num])

Deletes the comment given by key. The optional num value can be used to specify which comment to delete, given duplicate keys. Leaving num out will result in only the first instance being deleted. Returns undef if key or num are invalid. If all goes well, the value of the deleted comment is returned.

clear_comments ([@keys])

Deletes all of the comments which match keys in the input array or all of the comments in the stream if called with no arguments. Returns undef if any key is invalid, although all keys in the input array up until that key will be cleared. Returns true otherwise.

write_vorbis ()

Write object to its backing file. No comment modifications will be seen in the file until this operation is performed.

path ()

Returns the path/filename of the file the object represents.

Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel.

This places Vorbis in the same competitive class as audio representations such as MPEG-4 (AAC), and similar to, but higher performance than MPEG-1/2 audio layer 3, MPEG-4 audio (TwinVQ), WMA and PAC.

Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.orgs Ogg multimedia project.

libVorbis is the core Ogg stream / Vorbis engine.

The GTK Ogg Vorbis Tag Editor allows you to edit the tag information in ogg vorbis files.
The following basic libraries are necessary for assembly of the program:
GTK 1.2.5 or is higher (http://www.gtk.org)
Ogg Vorbis the library of the version 1.0beta3 or above (is desirable from CVS) (http://www.vorbis.com)
Assembly and installation:
./autogen.sh - prefix =/usr make
make install-strip
To start the program you have to type:
oggedit
or
oggedit [file]
Enhancements:
- The support of localization is added (while is added only Russian)
- The information about "genre", "location", "copyright", "track number" and "organization" is added
- It is a lot of other changes both in a graphic part of the interface, and in the basic code

Audio::AMR::Decode is a Perl extension do decode .amr files.

SYNOPSIS

use Audio::AMR::Decode;
Audio::AMR::Decode::amr2raw(infile.amr, outfile.pcm);

This module will attempt to decode an amr encoded audio file to a raw pcm audio encoded file.

The package contains C-source files for the optimized fixed-point speech decoder. The optimized fixed-point speech decoder is bit-exact with 3GPP TS 26.073 fixed-point speech decoder version 4.1.0.

Teralogic 880 HDTV decoder Linux driver.
Remember that this driver has no video capture capability. The kernel module
uses three devices per TL880 card in /dev/tl880 to allow all users to mmap the
memory regions of the TL880, or use the ioctl interface to control the card.
The tools are then used to upload the firmware, set external sync, turn on color
bars, display a mouse cursor, and tweak the OSD. Thats all that the driver can
do so far. There is also I2C bus support. For the latest known bugs, see the
web site and mailing list.
To test the I2C bus(es), you will need the lm_sensors package. Load the
i2c-dev, i2c-algo-bit, and tl880.ko kernel modules, then run i2cdetect for each
bus displayed in the kernel message log (each card has a different number of
buses). If you have any output beside all XXs, note the address and bus
number, and run i2cdump [bus] [address]. For example, the NXT2000 on the MyHD
has address 0x14 on bus 1, so i2cdetect 1 shows a response from address 0xa, and
i2cdump 1 0xa shows the registers of the NXT2000.
Enhancements:
- Many internal improvements in this version, though few new user-worthy
- features.
- Improvements to card initialization.
- New ioctl interfaces.
- Improved VPX chip support.
- More chip features documented.
