- Fixed audio-playing in container (video) files. Now audio can be read directly from the video file and does not have to be extracted to a separate audio-file anymore (tested with vob, avi and flv. Note: With some versions of FFMPEG flv does not work correctly).

- Added "pCodecCtx^.workaround_bugs := FF_BUG_AUTODETECT" to let FFMPEG automatically handle known bugs. This might be interesting for video-decoding too.
