A friend's son graduated from college last week. They asked me to see about making a copy of the video from the service.

Here's the web page with the video:

http://www.emory.edu/commencement/webcast/index.html

Here's I think the flash code related to the video. I tried saving the mp4, but it's only 73KB, I change the rtmp to http and that doesn't let you get the file. Any advice?

<script src="http://realaudio.service.emory.edu/clients/jwplayer5.9/jwplayer.js" type="text/javascript" ></script>
<div id="mediaplayer" ></div>
<script type="text/javascript">
jwplayer('mediaplayer').setup({
'id': 'playerID',
'width': '520',
'height': '316',
'provider': 'rtmp',
'streamer': 'rtmp://realaudio.service.emory.edu/EVENTS/COMMENCE/',
'file': 'commence2012.mp4',
'modes': [
{type: 'flash', src: 'http://realaudio.service.emory.edu/clients/jwplayer5.4/player.swf'},
{type: 'html5',
config: {
'file': 'http://realaudio.service.emory.edu/m3ugen/iPhone-src/EVENTS/COMMENCE/commence2012.mp4',
'provider': 'video'}
}
]
});
</script>

Download this package (http://files.videohelp.com/u/207848/emory.zip) and extract it in a folder!! Then double click on command.bat! ;)

THANK YOU! It's doing it now, but it looks like it'd be fine. Can I ask - would you then convert it into a more 'usable' / easier to play format? mp4?

Any recommended converter you like?

[svnpenn]

ffmpeg -i commence2012.flv -c copy commence2012.mp4

[babaganoosh]

Wow! You guys are great!

[babaganoosh]

Sorry, one more question.

Is there a way to tell what the quality of the flv file is so that when i convert it to mp4 (using ojosoft total video converter), I don't choose super high quality and it takes so much longer to convert but there's no improvement in quality since I started with an flv that is 'good' quality and could have just chose a good quality for the mp4?

Right? (using somewhat of an analogy) making a blue ray of an old vcr tape will not give you blue ray quality. You'll just have a much bigger file and the quality will be vcr quality? Or taking a picture of a document with 14MP camera gives the same legibility of the text as a 200dpi scan would, but you have a much larger file?

Why don't you just use ffmpeg like the previous poster suggested? ffmpeg remuxes as opposed to converting and should be quick and light on your CPU.

Greeny - why? ignorance : )

I will use it!

Just did. Damn! Much faster! and a problem I had with ojo was that the original feed was widescreen and the ojo mp4 is 640 x 480.

ffmpeg kept the proportions.

I make problems for myself : (

1 question - the audio of the mp4 using ffmpeg is just a tiny hair off from the video. Looking at the flv, they are in sync. Anything I can do about that?

You guys are GREAT!!!

Try this:
ffmpeg -i commence2012.flv -c copy -async 1 commence2012.mp4

[babaganoosh]

Thanks. I tried that but it's still the same - certainly not a big deal, just enough to say 'yeah, they're not in sync 100%'.

I looked at

http://ffmpeg.org/ffmpeg.html#Audio-Options

and was going to try the asyncts option, but that's not a switch, right? not sure how to use that.

Never used asyncts before, so I can't help you there. Maybe someone else around here knows how to use it?

Also, what's the resolution of the video you got?

[babaganoosh]

how would I see that (the resolution)? watching the mp4, I don't have an info page that I can see in quicktime.

Well, how big is the filesize?

[babaganoosh]

1.3 Gb

[greenythebeast]

Ah, alright. Well I found that there is a 720p copy of the video file on the server as well:
rtmpdump -r "rtmp://realaudio.service.emory.edu/EVENTS/COMMENCE/" -a "EVENTS/COMMENCE/" -f "WIN 11,2,202,235" -W "http://realaudio.service.emory.edu/clients/jwplayer5.4/player.swf" -p "http://www.emory.edu/commencement/webcast/index.html" -y "mp4:commence2012-2.mp4" -o mp4_commence2012-2.flv
So if you want a higher quality version you could download that. Maybe the sync issue would be fixed in that too.

use ffmpeg -i yourfile
(do not specify an output file!)

will output helpful info:

Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 720x404 [SAR 404:405 DAR 16:9], 947 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 47.95 tbc
