FLV1 video codec

mathieu1984 · Postby **mathieu1984** » 29 Sep 2008 18:24

Hello,

I use VLC 0.9.2 under windows to stream from my webcam. I want to display the output via a web-based flash player.

I have seen many posts using the FLV1 video codec, but I do not have this one in the list of available video codecs.

How have I to proceed to have this codec available in VLC?

Thanks by advance.

Nobody can aswer ?

Is there an other way (h264 + mp3 in a flv mux ?)

Try this page http://wiki.videolan.org/Flash_Video. It give you a Transcode command guide (no FLV1 in GUI).

With this transcode command, the streaming starts, and I can access it via a remote web-based flash player, but I have no video, just sound.

If I add "mux=flv" (#transcode{vcodec=FLV1,acodec=mp3}:std{access=http,mux=flv,dst=0.0.0.0:8081/stream.flv}), the streaming doesn't start.

Any idea ?

In mux you should try "mux=ffmpeg{mux=flv}" instead of "mux=flv" .

I'm presently trying to set-up the same type of solution.

Could you say me which VLC version, OS and FLV Player are you using ?

Thank you

I use VLC 0.9.2 under Windows XP Pro, and JW Player on the web page side.

Ok.

Under Windows I've seen some troubles with arguments.

Maybe with

vlc.exe yoursource --sout #transcode{vcodec="FLV1",acodec="mp3"}:std{access="http",mux="ffmpeg{mux=\"flv\"}",dst="0.0.0.0:8081/stream.flv"} ?

If I had a "mux" argument, the streaming does not start in VLC.

I have been able to have video + sound at a moment, I don't understand why it worked (I had not changed any argument...)

Maybe is it better with VLC 0.9.3 ?

With my line I've been able to start streaming but I've encountered the same problem as yours. Sound but no video

According to the changelog ( http://www.videolan.org/developers/vlc/NEWS ) I don't think so ...

How do you access the flv with a web based player?

-As i can stream, but can't get JW flv player to work with it.

I stream by setting up one vlc instance to stream to http and one to stream to flv, like this:

I've downloaded JW Player from this page : http://www.jeroenwijering.com/?item=JW_FLV_Player

And, in the folder of the JW archive extraction I'm making a text file called index.html ( or what you want with .html extension ) with this content :

Code: Select all

<html>


<p id='preview'>The player will show in this paragraph</p>

<script type='text/javascript' src='swfobject.js'></script>
<script type='text/javascript'>
var s1 = new SWFObject('player.swf','player','400','300','9');
s1.addParam('allowfullscreen','true');
s1.addParam('allowscriptaccess','always');
s1.addParam('flashvars','file=http://localhost:1234/stream.flv');
s1.write('preview');
</script>
</html>

Then, I just need to open this file in my webbrowser.

I've tested a nightly build vlc release and it's working. Here is my line :

vlc http://mafreebox.freebox.fr/freeboxtv/playlist.m3u --sout
'#transcode{vcodec=FLV1,scale=0.25,acodec=mp3,samplerate=22050}:std{access=http,dst=192.168.0.7:1234/stream.flv}'
-I http --http-host 192.168.0.7:8080

And, if I use my webbrowser to access to 192.168.0.7:8080 there is a link in the bottom of the page to access to a flash based video player. Wonderful

I've put everything behind an apache proxy server so, it's very clean

I've got trouble with JW Player as well. First sound only and the play-icon, if I press it, the video starts. But it seems as if JW Player just downloads a segment and later on messes up.
And the guys from JW Player don't really understand that vlc does indeed stream stuff, I think...
