How to reduce size of moov atom of H.264 movies to improve streaming start for smartphones ?
14 avril 2013, par alebedevWe run a video service streaming movies to smartphones (iOS&Android).
We are encoding in H.264+AAC and using the mp4 container.
We have a problem that long movies (60 minutes+) take a very long time to
start playing and have tracked this down to the large size of moov
atom for these movies.
For 110 minute movies the atom is as large as 4.2Mb which obviously takes a long
time to download to a smart-phone over 3G !Is there anyway to make the moov atom smaller ? We can reduce it bit
by dropping the audio sampling rate, but obviously anything below 22kHz
would not really be acceptable.We are using ffmpeg as the encoder, and MP4Box to move the metadata
to the front of the file. Is there any way to get it to make
a smaller moov ? Any other encoders out there which make a smaller moov ?For example...
Big size (280 Mb, 1h 49min) streamable mp4 (h.264, AAC) file have a big header size (4.2 Mb). File was encoded by two pass ffmpeg and MP4Box for replacing metadata into beginning of the file :

------------------------------------------------------On slow connection this movie start playing after 30-40 seconds until header info (4.2 Mb) downloading. I need that movie start playing fast as it possible. And i have next questions :
-
How reduce size of movie header ?
-
How reduce size of
/moov[0]/trak[1]/mdia[0]/minf[0]/stbl[0] and why it so big when
sample rate 44100 ?

Playing videos using HTML5 Tag
20 novembre 2012, par Haja MohaideenI am creating a website where videos need to be streamed. The content creator uploads .mov file to the server. Upon uploading, I convert to the following formats using FFMPEG, .mp4, .webm, and .ogg.
I am now trying to allow the video to be viewed from multiple browsers and handheld devices. The code is as follow :
<code class="echappe-js"><script> <br />
var video = document.getElementById(&#39;video&#39;);<br />
video.addEventListener(&#39;click&#39;,function(){<br />
video.play();<br />
},false);<br />
</script><script type="text/javascript" src="http://stackoverflow.com/feeds/tag/jwplayer.js"></script><script type="text/javascript"><br />
jwplayer("video").setup({<br />
modes: [<br />
{ type: &#39;html5&#39; },<br />
{ type: &#39;flash&#39;, src: &#39;player.swf&#39; }<br />
]<br />
});<br />
</script>The video works on all browsers. But, it is refusing to play on Android. When I click the play button, it shows as loading only.
I am testing on 4.0.3.
FFMPEG conversion codes :
webm
exec("ffmpeg -y -i file.mov -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b 345k -s 640x360 output.webm", $command_output, $result);ogg
exec("ffmpeg -y -i file.mov -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b 345k -s 640x360 output.ogv", $command_output, $result);flv
exec("ffmpeg -y -i file.mov -ar 44100 -ab 96 -f flv output.flv", $command_output, $result);For MP4 :
sudo ffmpeg -i file.mov -s 320x240 -c:v libx264 -pix_fmt yuv420p -profile:v baseline -preset slow -acodec aac -strict experimental -ac 2 -r 15 -ab 44100 -aspect 16:9 output.mp4

How to set Avconv constant bitrate to output flv file ?
5 novembre 2012, par ispasovI am trying to encode a flv file which has bitrate 512k. I have created the folowing command :
avconv -i input_file.mpg -f flv -c:v flv -b:v 512k -c:a libmp3lame -b:a 64k -ar 44100 -s 400x300 ouput_file.flvDuring the encodding the terminal shows higher bitrate - from 650k falling to 580k.
After the file has finnished encodding I can't see in it's properties the bitrate - it is N/A.I have tried -minrate and -maxrate options but no result also.
Can someone help me with that ?
