crtmpserver it is a high performance streaming server able to stream (live or recorded) in the following technologies: to and from Flash (RTMP, RTMPE, RTMPS, RTMPT, RTMPTE), to and from embedded devices (such as iPhone and Android), from surveillance cameras, and with IP-TV using MPEG-TS and RTSP/RTCP/RTP protocols. Also, crtmpserver can be used as a high performance rendesvous server. For example, it enables you to do audio/video conferencing, online gaming, online collaboration, and simple or complex chat applications.
DarkIce is a live audio streamer. It records audio from an audio interface (e.g. a sound card), encodes it, and sends it to a streaming server. DarkIce can record from OSS audio devices, ALSA audio devices, Solaris audio interfaces, and Jack sources. DarkIce can encode into MP3, MP2, Ogg Vorbis, and AAC formats, and can send the encoded stream to ShoutCast, IceCast 1.3.x and 2.x, and the Darwin Streaming Server.
mod_musicindex is an Apache module aimed at being a C alternative to the Perl module Apache::MP3. It allows nice displaying of directories containing MP3, Ogg Vorbis, FLAC, or MP4/AAC files, including sorting them on various fields, streaming/downloading them, constructing playlists, and searching. It also provides features such as RSS and Podcast feeds, multiple CSS support, and archive downloads.
Linphone is an audio and video Internet phone with GTK+ and console interfaces. It uses the SIP protocol, and is compatible with most SIP clients and gateways. It can use various audio and video codecs such as Speex, GSM, G711, G722, ilbc, amr, Theora, H263-1998, MPEG4, H264, VP8, and snow.
Podget is a simple podcast aggregator optimized for running as a scheduled background job (i.e. cron). It features support for downloading podcasts from RSS and XML feeds, for sorting the podcasts into folders and categories, for importing podcast URLs from iTunes PCAST files and OPML lists, automatic M3U and ASX playlist creation, and automatic cleanup of old podcasts. It also features automatic UTF-16 conversion for podcasts hosted on Windows servers.
The GNU Compact Disc Input and Control library encapsulates CD-ROM reading and control for applications wishing to be oblivious to the OS- and device-dependent properties of a CD-ROM. It provides an API for access to SCSI-MMC (multimedia commands) and support for CD image types like BIN/CUE, cdrdao's TOC, and Nero's NRG, which gives applications using the library the ability to read disc images as though they were CDs. ISO-9660 filesystem support is included, as are utility programs for displaying CD and CD-ROM drive information, reading the blocks of a CD, and extracting files from an ISO-9660 filesytem image. cdparanoia is also included.
pHash is an implementation of various perceptual hashing algorithms. A perceptual hash is a fingerprint of a multimedia file derived from various features from its content. Unlike cryptographic hash functions that rely on the avalanche effect of small changes in input leading to drastic changes in the output, perceptual hashes are "close" to one another if the features are similar. Potential applications include copyright protection, similarity searches for media files, or even digital forensics.
Mixxx is software for DJs that provides everything needed to create live mixes. It allows you to beatmatch songs and crossfade them together, like you would with turntables and a mixer. It runs without any extra hardware, and offers a wide range of advanced features including comprehensive MIDI controller and vinyl control support. To obtain the lowest latency and highest responsiveness, it uses hardware video acceleration and takes advantage of multi-core CPUs.
Audacity is a cross-platform multitrack audio editor. It allows you to record sounds directly or to import Ogg, WAV, AIFF, AU, IRCAM, or MP3 files. It features a few simple effects, all of the editing features you should need, and unlimited undo. The audio I/O uses PortAudio, which fully supports OSS, Mac OS X CoreAudio, and Windows WMME, and can be compiled with support for ALSA and Jack.
Infinity is a visualization plugin with light effects originally written for XMMS and now ported to Audacious. It supports full-screen mode, mouse resizing, and saved preferences. It is designed to be as end-user oriented as possible, so installation and manipulation are kept simple. It requires SDL and GTK+ 2.0 to run, and doesn't require 3D acceleration support.
