title: ffmpeg created m3u8 file can't be played by VLC
body: <p>I used command as below to convert m4v file to m3u8/ts files, </p>
  
  <pre><code>ffmpeg -i IMG_0048.m4v -codec: copy -bsf:v h264_mp4toannexb -start_number 0 -hls_time 10 -hls_list_size 0 -f hls IMG_0048.m3u8
  </code></pre>
  
  <p>but VLC can't play that m3u8 file, after I deleted lines as below, VLC can play the same m3u8 file, can you tell me why? </p>
  
  <pre><code>#EXT-X-VERSION:3
  #EXT-X-TARGETDURATION:11
  #EXT-X-MEDIA-SEQUENCE:0
  </code></pre>
