Gmerlin-avdecoder

Gmerlin_avdecoder is a general purpose media decoding library, written as a support library for gmerlin, but it can also be used by other applications. You don't even need gmerlin installed, only gavl. Most of it was written completely from scratch, but the sourcetrees of some other great software packages were used as reference documentation. Credits go to the authors of Xine, MPlayer, quicktime4linux and ffmpeg.

Gmerlin_avdecoder is one of the most complete general purpose media decoding libraries. The supported formats and codecs span a wide range of applications from consumer level (mp3, divx etc.) to high end production formats like 32 bit PCM and some professional uncompressed video codecs.

Features:

• Handling of sources with multiple tracks, each track can have an arbitrary number of audio-, video- and subtitle-streams.
• Support for both text and graphical subtitles
• Subtitles can also be read from external files if you choose to do so.
• Files, which contain multiple tracks, let you access the tracks individually. This is true for ALBW wrapped mp3s and concatenated OggVorbis files.
• High quality audio. You can always get the full acuracy, no matter if the file has 16, 24 or 32 bits. Compressed formats are decoded as floating point samples when possible.
• Track length detection and seeking support.
• Configuration of things like preferred network bandwidth is done on a per intstance basis.
• Extraction of metadata when available. International characters are converted to UTF-8 automatically if the source character set is known.
• Paths to binary codecs can be configured by the application or via environment variables. Editing cryptic files in /etc was not the best way to handle this.
• Support for URL redirectors
