RTSP only playing audio track with MP4 file

Greetings,

I am trying to stream VOD files using RTSP, but all tried players only plays audio track of the video.

this is my test URL rtsp://88.191.68.94/vod/mp4:EE21.mp4

I have no error on WMS logs, and if i localy play the file on Quicktime, VLC, WMP or iPad i have no problem at all.

Any idea ?

Thank you !

I get audio and video in VLC version 1.05. But not in Quicktime. Windows Media Player is not supported (Though we have found that it works with vod cupertino streaming)

Can you post this video for download on a web server? You can send a link to support@wowza.com. Please include a link back to this thread.

This file is MPEG4-Part 2 and not H.264. It must be transcoded to H.264 (AVC):

Format : MPEG-4 Visual
Format profile : Simple@L1

Thank you, now it works with this sample movie, but it is dedicated to iThings from Apple. I still have to find a codec that works with WMS, BBerry & iThings as basic MP4 seems not to work, any suggestion ?

Also, please apply path 5, there are RTSP improvements. Note the IMPORTANT special instructions regarding this patch

h.264 video in mp4 container will work with all clients that Wowza supports. It is a good idea to keep the encoding parameters as simple as possible: Baseline 3 profile.

Also, see these guides:
