HTTP Dynamic streaming (only manifest.f4m and no smil)

Wowza Streaming Engine

Hi. I’m developing a Flash OSMF based video player to play multi bitrate http dynamic streaming. The only thing I needs is a link to manifest.f4m file with all the metadata of the video, including a set of urls to video files for different bitrates. As far wowza fully supports HTTP Dynamic Streaming i thought i won’t be a problem. But i did not find any tutorial or forum thread for it.

In a tutorials manifest file is generated on the fly for only one file without multi bitrate data.

For this purpose you advise to generate a smil file. But for me is kind of workaround because OSMF natively support HTTP multi bitrate dynamic streaming via manifest.f4m and smil is a plugin.

Is it possible with Wowza media server to deliver multi bitrate content only with use of manifest.f4m file, without smil as FMS can. ?

You need both:

The vod tutorial has a multi-bitrate section that shows the smil, which is just a text file not a plugin.

Also, take a look at the clientOSMF folder in [wowza-install-dir]/examples/SimpleVideoStreaming.

Test that you can play each item directly. Make sure you are using mp4: prefix on on the name of files with .mp4 or other quicktime extension.

Tnx for quick reply. It was not clear for me that multi bitrate manifest is generated runtime if asked with smil link

Stream: http://[wowza-ip-address]:1935/vod/smil:bigbuckbunny.smil/manifest.f4m

Now i got it.

With the clientOSMF example i got wowza crash with

ERROR server comment - MediaReaderH264SanJose.indexFile:java.lang.NullPointerException

I hope i’ll fix it my self soon. Thank you.
