 // FFmpegGlue is an interface between FFmpeg and Chrome used to proxy FFmpeg's
 // read and seek requests to Chrome's internal data structures.  The glue works
 // through the AVIO interface provided by FFmpeg.
 //
 // AVIO works through a special AVIOContext created through avio_alloc_context()
 // which is attached to the AVFormatContext used for demuxing.  The AVIO context
 // is initialized with read and seek methods which FFmpeg calls when necessary.
 //
 // During OpenContext() FFmpegGlue will tell FFmpeg to use Chrome's AVIO context
 // by passing NULL in for the filename parameter to avformat_open_input().  All
 // FFmpeg operations using the configured AVFormatContext will then redirect
 // reads and seeks through the glue.
 //
 // The glue in turn processes those read and seek requests using the
 // FFmpegURLProtocol provided during construction.
 //
 // FFmpegGlue is also responsible for initializing FFmpeg, which is done once
 // per process.  Initialization includes: turning off log messages, registering
 // a lock manager, and finally registering all demuxers and codecs.
