Jwplayer and Wowza. Very slow to start video with rtmp and smil.

Hi,

it's a serious issue for me. Pls help!

Wowza 4.0.2, a fast linux server, fast internet, and jwplayer 7.0.3.
With direct rtmp the start of video is immediate:
http://www.iltuocorso.secchiemoschino.it/testvideo/TestRtmp.htm

With smil file is terrible: almost 40 seconds to start!
http://www.iltuocorso.secchiemoschino.it/testvideo/TestSmil.htm

And the mp4 called file is the same in both test !

Smil file is here:

<?xml version="1.0" encoding="UTF-8"?>
<smil title="">
<body>
<switch>
<video src="mp4:55edeef6d69bd7.37613035_M03" systemLanguage="IT" width="640" height="360" >
<param name="videoBitrate" value="750000" valuetype="data"></param>
</video>
<video src="mp4:55edeef6d69bd7.37613035_M01" systemLanguage="IT" width="426" height="240" >
<param name="videoBitrate" value="400000" valuetype="data"></param>
</video>
</switch>
</body>
</smil>

What's wrong??? I tried adding bufferlength but it seems this is not important.
The result (also with 0.1) is the same. A lot of time before video starts.

When the video starts it seems good. Rewind and Forward are fast, as you can see.

Thank you in advance

a little addendum: Wowza is 4.2 not 4.0.2. The issue is also with jwplayer 6.

Hello,

I looked at both streams and seem to load both creatives with reasonable wait less that 1 sec. If you check your network in the console, what is the ms read out for loading the player.js vs. the smil file?

Hello Randy,
147 ms to read the smil file and 58 for jwplayer.js.
The Player page load fast. When I push the play button the circle starts to rotate for about 40 seconds. I tried also from another pc located far from my office. Same trouble. Same wait time.
What can I do to check what happens during that 40 seconds?

Last update: Tried on three different pc (firefox or chrome with last flash version): same issue. Also testing from our webfarm in Milan the result is the same delay (always 40 sec). Form the Streaming server machine (Linux Centos 7 with gnome in Germany) the smil start immediately, as from your site. What does it mean? It seems there is no traffic network on the port during wait (I used a traffic sniffer to check my pc ethernet port). From the Log of wowza there is nothing between the last command and the open log.
For example your smil connection:

And my smil connection:

Please notice the delay before the open log line

Another try session: From two different Mac in another location: sometimes a wait time of 2 minutes (!) before video starts and sometimes 17 seconds...
If it's a network issue is surely related to the flash player (bandwidth check???) . Please notice that previous HLS test with smil was ok. There was no any wait time on android.
Please give me an help, otherwise I have to change player product...

Hello Alessandro,

We are going to have to get more detail on this but I believe the forum may not be the ideal platform to place that information. Please send a support request to: support@jwplayer.com and reference: Jwplayer and Wowza. Very slow to start video with rtmp and smil (RANDY). I will reply with next steps for you.

Kindly,
