android - jwplayer slow buffer video lag -


i’m using jwplayer mobile site... need mobile capability html5 player.. choose jwplayer.

i'm converting video ffmpeg

ffmpeg -i input.mp4 -vcodec h264 -b 1400k -s 1280x720 -acodec libfaac -ac 2 -ab 128k -movflags faststart -y output.mp4

i'm using centos apache server , installed h264 streaming module

my videos starting fast @ first.. in middle when internet slows , buffering slows down.. @ same time video lags , sounds continues few second ... @ point video , audio sync well. happening because of slow buffer problem.. after whole video buffered when replay..full video playing . i used android phones chrome browser check . need playing position show load icon , wait if buffer slows.. not lag video

i cant lower video bitrate.. because of competitors.. want solution html5 player.. have added jwplayer code. 

<script>    jwplayer("myelement").setup({         width: "100%",         skin: "skin.xml",         autostart: true,          sharing: {},       image: "http://example.com/mp4/screen.jpg",        sources: [{         file: "http://example.com/720.mp4",         label: "720p",         "default": "true"       },{         file: "http://example.com/hd/hd.mp4",         label: "hd"       },{         file: "http://example.com/mp4/480x320.mp4",         label: "480p"       }],       startparam: "starttime",         stretching: "exactfit",         autostart: false,     });    </script>
