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](http://osmf.org/dev/osmf/specpdfs/FlashMediaManifestFileFormatSpecification.pdf) 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](https://www.wowza.com/docs/how-to-set-up-video-on-demand-streaming) 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](http://help.adobe.com/en_US/HTTPStreaming/1.0/Using/WS8d6ed60bd880807c48597a9e1265edd6cc0-8000.html#WS54e1cfabeb2c71e628e59bbd1263491a443-8000). ? ---

You need both: ```auto http://[wowza-address]:1935/vod/smil:multivod.smil/playlist.m3u8 ``` The [vod tutorial](https://www.wowza.com/docs/how-to-set-up-video-on-demand-streaming) has a multi-bitrate section that shows the smil, which is just a text file not a plugin. Richard ---

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

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. Richard ---

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. ---
