Hi,

How to build SMIL files from transcoder on live edge?

I’ve read this tutorial but still I have questions.

[https://www.wowza.com/docs/how-to-create-and-play-smil-files-with-streams-created-by-wowza-transcoder](https://www.wowza.com/docs/how-to-create-and-play-smil-files-with-streams-created-by-wowza-transcoder)

I need dynamically build smil file per all streams.

Assume streams could be added/removed on the fly

Any help, appreciated

Sam,

Take a look at this article which shows how [create a MediaList dynamically](https://www.wowza.com/docs/how-to-use-java-api-calls-to-resolve-smil-file-requests)

The example is very basic, and really just shows example output, how the MediaList requests are intercepted and how to build a MediaList programmatically. You would have to add the resource connections and logic necessary to know when data has changed and what should be done. You might add a JDBC connection, for example, to query a database.

Hi,

I read this example, but it also has some problems.

All data is hard coded and you need to **recompile** every time you change your transcoder template.

Assume we have transcoder template t1 with some data d1, we change our data to d2.

At this case you need to **recompile** your code.

So this solution is not **flexible**.

Thanks.
