FFmpeg is a tool for converting audio, video, and subtitles. It includes libavcodec, the leading open source codec library. It also includes libavformat (implementing muxers and demuxers), libswscale (for very fast video scaling), and libavfilter (an advanced video filter system supporting arbitrary filter graphs), and libavutil (a utility library intended to supplement libc). A simple multimedia player is included too. An experimental streaming server for live broadcasts is also included.
The Extended Module Player is a command-line mod player for Unix-like systems that plays over 90 mainstream and obscure module formats from Amiga, Atari, Acorn, Apple IIgs, C64, and PC, including Protracker (MOD), Scream Tracker 3 (S3M), Fast Tracker II (XM), and Impulse Tracker (IT) files.
Pixel is an application for editing, retouching, manipulating, and animating RGB, CMYK, and HDR images. It was formerly known as Pixel32. It is available for Windows, Linux, Linspire, Mac OS X, BeOS, Zeta, QNX, MorphOS, FreeBSD, eComStation, OS/2, SkyOS and even old plain DOS, for both x86 and PowerPC architectures.
PECoMaTo stands for Picture-Embedded COntents MAnipulation TOol. It is basically designed to display any kind of information embedded in picture files, as well as checking, filtering, extracting, removing, adding, and fixing such information. In other words, it's a metadata processor. It supports the following file formats: JPEG/JFIF, Adobe PSD and FFO, and raw IPTC. It knows about the following metadata formats: JFIF, IPTC, Exif, Adobe, and Fotostation. More file and metadata formats might be supported later (TIFF, etc.).
HandBrake is a multi-threaded DVD to MPEG-4 ripper and converter. It can encode directly from DVDs (even encrypted ones) or from VIDEO_TS folders. AC3, LPCM, and MPEG audio tracks are supported. The output can be contained in MP4, AVI, or OGM files, and the output audio is encoded in either AAC, MP3, or Vorbis. Other features include support for 2-pass encoding, encoding of two audio tracks, a bitrate calculator, and deinterlacing, cropping, and scaling of the original picture.
The FAAC project includes the AAC encoder FAAC and decoder FAAD2. It supports several MPEG-4 object types (LC, Main, LTP, HE AAC, PS) and file formats (ADTS AAC, raw AAC, MP4), multichannel and gapless en/decoding as well as MP4 metadata tags. The codecs are compatible with standard-compliant audio applications using one or more of these profiles.
Audiality is a highly scalable and portable audio engine and synthesizer. MIDI files are used in combination with scripting and modular synthesis, to minimize file sizes and maximize flexibility. Audiality can be used as a music and sound effects player in multimedia productions, or as a realtime MIDI synthesizer.
