/**
 * A wrapper around the FFmpeg C libraries
 * designed for muxing encoded AV packets
 * into various output formats not supported by
 * Android's MediaMuxer, which is currently limited to .mp4
 * 
 * As this is designed to complement Android's MediaCodec class,
 * the only supported formats for jData in writeAVPacketFromEncodedData are:
 * H264 (YUV420P pixel format) / AAC (16 bit signed integer samples, one center channel)
 * 
 * Methods of this class must be called in the following order:
 * 0. (optional) setAVOptions
 * 1. prepareAVFormatContext
 * 2. (repeat for each packet) writeAVPacketFromEncodedData
 * 3. finalizeAVFormatContext
