First attempt (h264 + aac):

    ffmpeg -i testfile.mkv -vcodec libx264 -preset slow -b 768k -maxrate 768k -bufsize 1536 -vf scale=-1:720 -threads 0 -acodec aac -strict experimental -ac 2 -ab 44100 output.mp4

    Notes - video was able to play using VPlayer with Bubble
    Transformer:
      BubbleUPnP    Android Video Player - video + audio
      BubbleUPnP    Vplayer              - video + audio
      aVia          Android Video Player - didn't play
      aVia          Vplayer              - didn't play
      SD Card       Android Video Player - video + audio
      
    Revue:
      BubbleUPnP    Android Video Player - didn't play
      aVia          Android Video Player - didn't play


Second attempt reencode audio only to aac:
    ffmpeg -i testfile.mkv -vcodec copy -threads 2 -acodec aac -strict experimental -ac 2 -ab 44100 -scodec copy output.mkv

    Plays on all combinations... stutters on the network, but plays fine from sd card. 


Third attempt, reencode audio to aac and switch container to mp4
    ffmpeg -i testfile.mkv -vcodec copy -threads 0 -acodec aac -strict experimental -ac 2 -ab 44100 output.mp4


Fourth attempt, reencode video to h264, reencode audio to aac, and switch container to mp4
    ffmpeg -i testfile.mkv -vcodec libx264 -threads 0 -acodec aac -strict experimental -ac 2 -ab 44100 output.mp4
