decoding proxy lib/tool for ffmpeg

About

FFpocket is a tool for using ffmpeg's features. It is mainly developed to support Jubler's multimedia preview features. FFpocket can be built as a shared 'proxy' library and get used by larger projects that want to incorporate multimedia features using the ffmpeg library (avcodec/avformat).

Features

• Frame decoding for a video file
• Audio decoding for a multimedia file (video/audio)
• Precise frame/time seeking in the multimedia files (including b-frames)
• Audio downsampling and special minmax averaging, refered to as 'caching'

'Caching' is used by Jubler to produce the visual representation of a multimedia file's waveform.
