In the engine manager, on the sidebar of a live application it says this:

> Select the Record all incoming streams check box to record all incoming streams published to this application by an encoder. The entire duration of the published stream is recorded to a single file in the application’s streaming file directory. If the encoder starts and stops, the file is versioned with a version number and a new file is started. You can control the container format used (MP4 or FLV) by specifying a stream name prefix in the encoder. If you specify the mp4: prefix, the stream is recorded to an MP4 (QuickTime) container. An MP4 container can only record H.264, AAC, and MP3 media data. If you specify the flv: prefix, the stream is recorded to an FLV container. **The FLV container is the only option if you’re recording with Flash Player.**

The out of date part is bolded and underlined

I’m using Flash Player to publish streams as mp4s right now.

Further, it seems to contradict this:

> Use Wowza Streaming Engine media server software to build a streaming solution at any scale.

> With Flash 11 you can now publish h.264 video using its built-in encoder. Previous versions of Flash were limited to Sorenson Spark video. However the audio options are still limited to NellyMoser and Speex which are not supported in non-Flash clients. This article shows how to setup a Flash application to publish h.264 video and Speex audio to a Wowza Transcoder application using a template to transcode the Speex audio to AAC. The video is set to Baseline 3.

I might be misunderstanding what is meant by the “flv container being the only option with Flash Player”, but it seems to not be true.

Hi,

I think you are right as to the confusion. It’s really supposed to mean "if want to record flash content, so VP6 or Sorenson Spark Video and NellyMoser Audio etc, then a FLV container is required, if they are to stay in that format.

Some re-wording definitely is required. Thanks for your feedback. I’ll pass this along to our writers for sure.
