title: FFMPEG HLS video speed is too fast
body: <p>I am trying to make a <code>.m3u8</code> hls playlist locally on my computer. I am using Windows 7, 32 bit.</p>
  
  <p>I am a begginner of <code>FFMPEG</code>, and finally I combined some commands into this:</p>
  
  <pre><code>ffmpeg -re -rtbufsize 999999k -y -f dshow -video_size 640x360 -r 15 -i video="ManyCam Virtual Webcam" -c:v libx264 -crf 18 -profile:v main -maxrate 999999k -bufsize 99999k -pix_fmt yuv420p -flags -global_header -hls_time 10 -g 3 -hls_list_size 2 -hls_wrap 0 -start_number 1 D:\\stream\stream.m3u8 -tune zerolatency 
  </code></pre>
  
  <p>The problem is that while playing the m3u8 playlist with VLC or a HLS player, the video speed is faster than normal.</p>
  
  <p>If you need more info, please comment.</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>If I play one of the <code>.ts</code> files, the problem is the same.</p>
  
  <p>Thank you so much!</p>
