Tried youtube-dl & streamlink but failed.
So, I use FFmpeg because it success to download the video and audio. I have read FFmpeg documentation but I have no idea what command should I use.
What command should I use to select another quality ? (ex : audio 64 kbps, video : 720p)





Note : just change (dot) to

Making progress bar with FFmpeg duration value
11 novembre 2014, par user2978381I am mainly a back-end developer. I have rarely used javascript. But for real time update now I have to use javascript, ajax, jquery or something like that.
My php script outputs this value "100%" at the end of the conversion.
echo "Progress: " . $progress . "%";The $progress variable actually holds numeric data like 10 and I want to use this value for making progress bar. The value of the $progress variable changes every second and I need to capture this value.
So if I want to implement this value in the following html file what will I do actually ?
<code class="echappe-js"><script src="//code.jquery.com/jquery-1.10.2.js"></script><script src="//code.jquery.com/ui/1.11.2/jquery-ui.js"></script><script><br />
$(function() {<br />
var progressbar = $( "#progressbar" ),<br />
progressLabel = $( ".progress-label" );<br />
<br />
progressbar.progressbar({<br />
value: false,<br />
change: function() {<br />
progressLabel.text( progressbar.progressbar( "value" ) + "%" );<br />
},<br />
complete: function() {<br />
progressLabel.text( "Complete!" );<br />
}<br />
});<br />
<br />
function progress() {<br />
var val = progressbar.progressbar( "value" ) || 0;<br />
<br />
progressbar.progressbar( "value", val + 2 );<br />
<br />
if ( val < 99 ) {<br />
setTimeout( progress, 80 );<br />
}<br />
}<br />
<br />
setTimeout( progress, 2000 );<br />
});<br />
</script>Loading...
