Hi all -

Trying to implement VOD with .m3u links for viewers.

It worked in 3.03, but is not working in 3.4.2

here is the link I am providing:

[http://IPADDRESS:1935/vod/mp4:filename.mp4/playlist.m3u8](http://IPADDRESS:1935/vod/mp4:filename.mp4/playlist.m3u8)

Users report:

video says cannot load error message

mimetype not supported

the operation could not be completed - on 1st gen devices

any suggestions?

Thanks in advance

Can you describe the stream settings?

1: Video and Audio codec?

2: Frame Rate

3: Bitrate

4: Keyframe interval(GOP length)

For iOS devices, video should be H264, audio should be ACC. If mp3 then the settings should be 44100Hz, 128kbs.

Profile should be set to “baseline”. A GOP length of 2 seconds is recommended.

You can look at [this chart](http://en.wikipedia.org/wiki/H.264#Levels) to see what frame size to use based on fps.

You can use [JW Player 6](https://www.wowza.com/docs/how-to-use-jw-player-with-wowza-streaming-engine) for HLS streaming to the desktop and HLS devices.

JW Player 5 or 6 I can use either one.

I am sorry, I made the assumption you were talking about iOS devices. Can you specify which client you are using for playback?
