#4870: Incorrect Aspect Ratio
--------------------+-------------------------------------------------------

 When first starting playback of the test.avi video referenced in #4567
 we incorrectly set the aspect ratio to 2.   Later(even just 1 second
 later) if we for example seek back to the start of the video it is
 corrected, as well after a few seconds of playback we eventually get the
 right aspect and correct accordingly.


 From what I can see when we first call AvFormatDecoder::InitVideoCodec()
 enc->sample_aspect_ratio has no value and we end up defaulting to just a
 single width/height for the aspect.

  But after a few frames have been decoded or, the next time
 AvFormatDecoder::H264PreProcessPkt gets called the sample_aspect_ratio is
 set so we can then properly calculate the aspect.

 I've tested this with other players and they don't seem to have the same
 problem.
