Hello,

I have been using Wowza to interface with RTSP sources. One of the features I have made use of is startup streams and stream files. The stream files have the rtsp information in them, and they’re automatically connected to Wowza when the server boots up.

I am calling the Wowza REST API from another server to set up these files and startup streams, however I now have a need to dynamically modify these stream files and start up streams within our Java code in the Wowza server itself. Specifically if an rtsp source is detected no longer valid, I want to automatically delete it from our server using the Java server API, but I am not able to find an appropriate method to do so.

I was able to find the methods getStartupStreams and addStartupStream on page 2787 of this document: [https://www.wowza.com/resources/WowzaStreamingEngine\_ServerSideAPI.pdf](https://www.wowza.com/resources/WowzaStreamingEngine_ServerSideAPI.pdf), but I don’t see a corresponding modify or delete API. [https://www.wowza.com/resources/WowzaStreamingEngine\_ServerSideAPI.pdf](https://www.wowza.com/resources/WowzaStreamingEngine_ServerSideAPI.pdf)

I was also not able to find any APIs to deal with stream files directly.

Are there any JAVA Server APIs to add/edit/delete the entries in [Wowza install dir]/conf/StartupStreams.xml as well as add/edit/delete the stream files in [Wowza install dir]/content?

Thanks very much,

Allan

I’ve done some work with this and use [java.io](http://java.io) to write .stream files to the appropriate content directory for an application. I haven’t worked with auto-start APIs, though.

Hi Allan,

StartupStream objects that are added through the `addStartupStream()` method are only held in memory for the duration of the Wowza Server’s running time (wiped on restart). There is a `stopStartupStreams()` method, but this would stop all startup stream objects. It may be best to use the [MediaCaster API](https://www.wowza.com/docs/how-to-mediacaster-api-to-start-native-rtp-and-mpeg-ts-streams) to start and stop these streams in your code.
