Adaptive RTMP Streaming

hi,

I'm trying to set up to use RTMP adaptive streaing with JWPlayer and our video streaming server.

we have Helix and Wowza server both at the moment, the Wowza server works great with JWplayer.
however it always fails when I try to use JWplayer to play smil file for Helix server, the error I got is manifest is not valid or found.

I put smil file under IIS sever with web application. I can put it together with video files on server but no luck either.

the file is like:

<smil>
<head>
<meta base="rtmp://helixserver/Videos/ABS/" />
</head>
<body>
<switch>
<video src="mp4:Test_320x240.mp4" system-bitrate="528000"/>
<video src="mp4:Test_640x480.mp4" system-bitrate="928000"/>
<video src="mp4:Test_640x480.mp4" system-bitrate="1500000"/>
</switch>
</body>
</smil>


and the jwplayer like:

jwplayer("player").setup({
sources:
file: "/abs/testhelix.smil",
width:"600px",
androidhls:true,
fallback: false
});

it didn't work. can you help?

thanks
Tommy

The issue appears to be:

1) You’re disabling fallback, which is making the player render in HTML5 mode and thus ignoring the SMIL.
2) You’re then attempting to play an HLS stream, which is using a 302 redirect with an MP4 file extension.
3) The player still assumes that it can play the file in HTML5 mode, since it’s seeing the MP4 extension and assuming that it’s an MP4.
4) It can’t!
5) Error message

The best solution would be:
1) Set primary: ‘flash’ within your player embed. You’d need this for either HLS or RTMP regardless.
2) use type: ‘hls’ or type: ‘m3u8’ below your 302 redirect file. The player will then play this file as an HLS stream.

However, please be aware that 302 redirects are not playable unless absolute paths are specified for chunklists and TS segments. Loading a Manifest from ABC.com, redirecting to DEF.com will still cause the player to look for relative chunklists on ABC.com.

I hope this helps!

It’s not clear to me exactly what the problem is. Can you send me a link so I can troubleshoot more effectively? Also, you can remove the androidhls parameter, as this is rtmp, not hls.

It appears that neither of your video files are accessible.

jwplayer(“player”).setup({
sources: [{
file: “/abs/test.smil” <= not a valid source }, { file: "http://10.7.100.85:1935/mediacache/_definst_/smil:path1/Mobile/ABS/test.smil/playlist.m3u8" <= not valid
}],
width: “600px”,
androidhls: true,
fallback: false
});

Kind Regards,

Your smil URL in your setup is not pointing to the SMIL correctly. If you use the full url ‘http://media.weatherford.com/videotest/abs/testhelix.smil’, you’ll see that your player will work as expected.

Which version of IE are you using? Can you please ensure you have an up-to-date version of Flash installed in IE?

Hmm.. Your MP4 file appears to be redirecting to an M3U8 manifest via 302 redirect. So there are two things you should do here.

Andrew,

thank you so much, it works exactly as what you pointed out.
noticed one thing, for adaptive HLS streaming, seems only Wowza engine and JWplayer seamlessly support it, other streaming server can not do it, or I haven't done it right .

Thanks
Tommy
