Hello, We just started using Wowza Server, and we are having an issue with “Record all incoming streams” function. If we use Wirecast, Wowza records normally, however, if we use on ios app which we currently developing with github library (link: [https://github.com/slavavdovichenko/MediaLibDemos](https://github.com/slavavdovichenko/MediaLibDemos) ), wowza is not recording even we can watch it from test players and embedded players. How can we fix this issue? Specs: - Wowza version:4.0.1 - Wowza installed on Windows 2008 - We are using RTMP publish - There is no authantication, wowza accepts all incoming stream names under “live” application Thanks ---

Are you able to playback the stream while it should be recording? Do you see a publish event in the Wowza access log? Are there any WARN or ERROR lines following? Richard ---

NellyMoser audio and Spark video are what Flash publishes by default. Wowza supports NellyMoser audio and Spark video for playback in Flash clients, and for recording to .flv container. So you can record this to .flv container, but it will only playback in Flash. I’m not sure if it can apply to your iOS application, but this [guide shows how to configure Flash to publish h.264 video and Speex audio](https://www.wowza.com/docs/how-to-convert-flash-player-11-output-from-h-264-speex-audio-to-h-264-aac-audio-using-wowza-transcoder). Wowza can transcode the Speex audio to AAC, and that rendition(s) can be recorded to .mp4 container for HLS playback, Richard ---
