An attempt to port FFmpeg's FFplay.c

Media Container Architecture

Media Containers represent an input context, stream operations and decoding logic. The steps to successfully obtain usable datta are as follows:

• Open the container with a URL.
• Read the next packet and determine its media type
• Push the packet into the pending packet queue of the appropriate audio, video or subtitle component
• Decode packet from the pending packet queue into a frame. Move the packet to the sent packet queue.
• If 1 or more frames were decoded, clear the sent packets queue.
• Push the decoded frames into the component's frame queue
• Dequeue the raw frame from the component's frame queue
• Materialize the frame into a Media Frame (this converts the raw frame data into usable media)
• Release (Dispose) the materialized frame

Basic Test Cases:

• Audio and Video times both start at 0
• Video frames match end times with the following Video frame's start time
• Audio frames match end times with the following Audio frame's start time
• Video frame duration matches framerate
• Audio frame duration matches start time and end time comparted to the following audio frame
