This program normalizes media files to a certain loudness level using the EBU R128 loudness normalization procedure. It can also perform RMS-based normalization (where the mean is lifted or attenuated), or peak normalization to a certain target level. Batch processing of several input files is possible, including video files.

Streamlink is command-line utility that extracts streams from sites like Twitch.tv and pipes them into a video player of choice.

Wlstream is a screen capture tool for recording audio and video from a Wayland session.

Youtube-viewer searches and plays YouTube videos in a native player. It comes with various search options; it can search for videos, playlists and/or channels.

This package allows an ffmpeg command to run with progress. It is usually a complement to ffmpeg-normalize.

Libdvdnav is a library for developers of multimedia applications. It allows easy use of sophisticated DVD navigation features such as DVD menus, multiangle playback and even interactive DVD games. All this functionality is provided through a simple API which provides the DVD playback as a single logical stream of blocks, intermitted by special dvdnav events to report certain conditions. The main usage of libdvdnav is a loop regularly calling a function to get the next block, surrounded by additional calls to tell the library of user interaction. The whole DVD virtual machine and internal playback states are completely encapsulated.

MediaInfo is a library used for retrieving technical information and other metadata about audio or video files. A non-exhaustive list of the information MediaInfo can retrieve from media files include:

• General: title, author, director, album, track number, date, duration...

• Video: codec, aspect, fps, bitrate...

• Audio: codec, sample rate, channels, language, bitrate...

• Text: language of subtitle

• Chapters: number of chapters, list of chapters

MediaInfo supports the following formats:

• Video: MKV, OGM, AVI, DivX, WMV, QuickTime, Real, MPEG-1, MPEG-2, MPEG-4, DVD (VOB)...

• Video Codecs: DivX, XviD, MSMPEG4, ASP, H.264, AVC...)

Syncplay is a solution to synchronize video playback across multiple instances of media players over the Internet. When one person pauses/unpauses playback or skips to a position in the video, this is replicated across all media players connected to the same server and in the same "room" (viewing session). A built-in text chat for discussing the synced media is also included for convenience.

Matroska aims to become the standard of multimedia container formats. It is based on EBML (Extensible Binary Meta Language), a binary derivative of XML. EBML enables the Matroska Development Team to gain significant advantages in terms of future format extensibility, without breaking file support in old parsers. libebml is a C++ library to read and write EBML files.
