Rockbox is a free and open-source software replacement for the OEM firmware in various forms of digital audio players (DAPs) with an original kernel. [2] [3] It offers an alternative to the player's operating system, in many cases without removing the original firmware, which provides a plug-in architecture for adding various enhancements and functions.
IndirectSound is a freeware library that emulates DirectSound 3D using XAudio2, without using hardware acceleration. [16] DSOAL is an open source library that emulates DirectSound 3D and EAX using OpenAL. Either a hardware-accelerated OpenAL implementation or OpenAL Soft (which provides HRTF) can be used. [17]
Video Acceleration API (VA-API) is an open source application programming interface that allows applications such as VLC media player or GStreamer to use hardware video acceleration capabilities, usually provided by the graphics processing unit (GPU).
MPlayer is a free and open-source media player software application. It is available for Linux, OS X and Microsoft Windows. Versions for OS/2, Syllable, AmigaOS, MorphOS and AROS Research Operating System are also available. A port for DOS using DJGPP is also available. [4]
When the pipeline is in the playing state, data buffers flow from the source pad to the sink pad. Pads negotiate the kind of data that will be sent using capabilities. The diagram to the right could exemplify playing an MP3 file using GStreamer. The file source reads an MP3 file from a computer's hard-drive and sends it to the MP3 decoder.
The multi-platform open-source VLC media player and MPlayer can play Ogg Vorbis files, as can Winamp and foobar2000. Windows Media Player does not natively support Vorbis; however, DirectShow filters exist to decode Vorbis in Windows Media Player and other Windows multimedia players that support DirectShow. [63]
