Hi,

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

Wowza 4.2, a fast linux server, fast internet, and jwplayer 7.0.3 (but also with jwplayer 6)

With direct rtmp the start of video is immediate:

[http://www.iltuocorso.secchiemoschino.it/testvideo/TestRtmp.htm](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](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"?\>

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

Hi,

I suggest, as a test, trying the abr test files provided [here](https://www.wowza.com/docs/how-to-do-adaptive-bitrate-streaming) first.

Using the smil file and mp4 files from that guide, plus the jwplayer.smil, the playback should start quickly from a default vod application.

Is the same issue present with those files?
