Hi all,

can I assume that wowza supports the streaming of multimedia contet which contains many audio tracks? If so,can I assume that if I require a content wich has this property, I can on the fly change the track audio(multi language audio support).

Best Regards

Bedduzzo

Bedduzzo,

For video on demand, take a look at this guide:

[https://www.wowza.com/docs/how-to-select-audio-data-and-or-video-channel-from-a-multi-channel-mp4-file-by-using-imediareaderactionnotify](https://www.wowza.com/docs/how-to-select-audio-data-and-or-video-channel-from-a-multi-channel-mp4-file-by-using-imediareaderactionnotify)

I think IMediaReaderActionNotify onMediaReaderOpen only happens when stream starts.

I suppose it should be possible in Flash client using NetStream.play2 api that is used for Dynamic streaming.

Thanks for your answer,

but my doubt is if the audio/video content has two audio tracks and I start play it using audio track index 1, can I change on the fly the index 2 without restart the content streaming?

Thanks in advance for your answer.

Regards

Bedduzzo.
