Decoding a video file to video and audio frames (Delphi)

Task: Create a DLL library or a Delphi class for decoding video files to separate video frames (in JPEG format) and audio frames.

Preferred language: Delphi. VC++ is allowed if the result is compiled as a DLL.

The class or function should get as incoming parameter:

- file name of an input file;

- video output details (output resolution, compression level(optional)),

- audio output format (bitrate, hz, stereo/mono, codec (optional: MP3 or PCM);

- the class should provide as a callback function access to audio and video frames.

- callback function execution should be synchronized with video framerate

- if the audio output is MP3, you need to provide a routine to play back this stream.

Additional notes:

- third party libraries like FFMPEG may be used, but only if they allow distribution at least on LGPL basis;

- do not offer BASS library;

- if any other commercial third party components/libraries are assumed to be used, please confirm use with us.

- preferred video output format for the video frame: JPEG

- preferred audio output format: MP3. PCM is also allowed if MP3 is unavailable.

- should support input video formats:

*.MPG, *.MPEG, *.MP3, *.MP4, *.DAT, *.MOV, *.VOB, *.AVI, *.RM, *.RMVB, *.ASF, *.WMV
