title: What are mv, fd, aq, vq, sq and f in a video stream?
body: <p>I am playing video streams using RTSP over TCP using FFPLAY and it plays fine when the vq value increases, but stops after 5-6 seconds when only the value before M-V increases.</p>
  
  <pre><code>nan M-V:    nan fd=   0 aq=    0KB vq=    0KB sq=    0B f=0/0   
  ......
  ......
  
  Duration: N/A, start: 2.133467, bitrate: N/A
      Stream #0:0: Video: h264 (Main), yuvj420p(pc), 1280x1024, 15 fps, 25 tbr, 90k tbn, 30 tbc
  [swscaler @ 0x7fd9502403c0] deprecated pixel format used, make sure you did set range correctly
    "76.81" M-V: -5.409 fd=   0 aq=    0KB vq=    0KB sq=    0B f=2/2 ` 
  </code></pre>
  
  <p>Can someone please explain what these M-V, fd, aq, vq, f are, as well as the value before M-V ("76.81")?</p>
