I have an issue while playing SMIL file in my “ **custom player** ”. The issue is adaptive switching doesn’t work in my custom player in case of RTMP protocol, but my custom player play following smil url with adaptive switching and manual switching ( [http://mediapm.edgesuite.net/ovp/content/demo/smil/elephants\_dream.smil](http://mediapm.edgesuite.net/ovp/content/demo/smil/elephants_dream.smil) ). and also play HDS and HSL Streaming through wowza media server. I appreciate your help. ---

Hello there and welcome to the Wowza support forum. It is not clear what you are asking. It sounds like ABR works and it sounds like ABR doesnt work in your custom player? Server-side smil doesn’t work in RTMP player. You can use JW Player technique to bridge to the kind of ABR that works in RTMP players: RTMP Dynamic Streaming.
