Hello everybody.
I have a problem streaming video to iPhones and iPads.
I have a server with CentOS installed and it recieves live video stream with RTP protocol on 8888 port. In VLC I’ve used rtp://@:8888 to open that stream.
I need to transcode this stream to H.264 video and AAC audio with MPEG-TS incapsulation so iPhones and iPads could play it.
Is it possible to do with Wowza? I’ve used VLC, but it’s not fail-safe and there is a bug with idr\_pic\_id (x264 bug) which is the purpose of problems with playing stream. I’m looking for alternative and want to know, if it possible to re-stream my RTP stream to HTTP Live streaming with Wowza Media Server. And if it’s possible, how to configure Wowza for this aim. I’ve tried to find any guide, but I didn’t find any suitable guide.
I’ll appreciate any help.
Thanks.

Wowza does not do any transcoding. If the original RTP stream is encoded as H.264/AAC, Wowza can packetize it and transmit it for iPhone/iPad via HLS. To do this, you’d want to use the rtp-live application type and enable cupertino packetizer and streamer in your Application.xml.
Several folks posting here have had success with VLC and ffmpeg for transcoding a live stream, but those methods aren’t officially supported. If you dig around, you can probably find a config that works for you.

Upgrade to Wowza 2.2.0 and it should fix these errors.

An http url ending with /playlist.m3u8 is for Cupertino (IPhone, etc) streaming. If won’t work in a browser.
Try the Wowza LiveVideoStreaming Example player:
Server: rtmp://[wowza-address]:1935/live
Stream: mpegts.stream

Try reducing the keyframe frequency, and make sure it is a multiple of chunkDurationTarget, which is 10 by default, unless you add these properties and change it:
[Configure Apple HLS packets for HTTP streaming](https://www.wowza.com/docs/how-to-configure-apple-hls-packetization-cupertinostreaming))
Wowza adds this bandwidth info, and it should be very accurate if you are using 2.1.2.06. If you aren’t you can get Patch 6 here:
> **[Latest software updates for Wowza Streaming Engine](https://www.wowza.com/docs/wowza-streaming-engine-software-updates)**
>
> Get information about updating, upgrading, and installing the current build of Wowza Streaming Engine.
This package will help to create the required 64kbs stream:
[Create streams compliant with Apple App Store](https://www.wowza.com/docs/how-to-create-apple-app-store-compliant-streams))
But note that AAC audio is required, and the audio track must be 64kbs.
You should be able to get rid of these warnings:
> WARNING: INF tag with duration 2 seconds or more above the playlist’s target duration (10.000 seconds).
>
> 7: #EXTINF:16,
>
> ~~
But these are hard to get rid of completely, but a few should be okay:
> WARNING: Media segment bitrate outside of target playlist bitrate by 46.371 % (93677 vs. 64000 bps, limit is 10 %).
>
> 10: media\_1713.ts?wowzasessionid=329465679

Did you use a text editor for the smil? One possibility is that there are word processor characters in the file.

If you are doing origin-edge (?) and this is a liverepeater-edge, yes, use the appropriate LiveStreamPacketizer
With the auto-generate you don’t need a smil file if you play one video that has an 64kbs AAC audio track. Wowza auto-generates it. You can use a smil where one video has the 64kbs AAC audio track that you mark with wowza-audio-only=true, but you wouldn’t also make its system-bitrate 64000. In your example above, you might as well not use the smil.

On the edge, only use cupertinostreamingrepeater. Remove the others.
Completely take out the auto-generate configuration since you don’t need it. Use the smil item pointing to the 64kbs audio stream, as you were doing but without the wowza-audio-only=“true”

The StreamType should be “liverepeater-edge”

For Wowza’s role in your process, this is the essential guide:

You see “killed” in the logs, as below?
Wowza only logs the first few chunks. But chunking should continue.

One way to test it in a browser would be to use Safari and an HTML5 tag.
[http://www.w3schools.com/html5/tag\_video.asp](http://www.w3schools.com/html5/tag_video.asp)
If you do src=“http://…m3u8”, you should be able to see the HLS video. Only works in Safari/Mac, though, and you need a pretty recent version of OSX.

Thanks for the reply.
Original RTP stream is encoded as H.264/MP3, I’m not sure that iPhones would “understand” this, but I’m ready to try.
As I understood you the right way, you’re advicing to use this guide: [https://www.wowza.com/quickstart\_2\_1\_2.html#live-ip-camera](https://www.wowza.com/quickstart_2_1_2.html#live-ip-camera) step-by-step, but enabling cupertino and streamer, right? Is that guide is fully for me?
Could you advice, how to set Wowza for listening 8888 RTP stream on port? I should put rtp://@:8888 into [install-dir]/content/camera.stream?
Thanks again.

Ok, now that’s what I’ve done.
I’ve followed this guide: [https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder](https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder) - it contains rtp stream as input and mpeg-ts stream as output, so I’ve decided to use this guide.
In step: “4. Using a text editor create the file [install-dir]/content/mpegts.stream set the contents of this file to udp://0.0.0.0:10000 (if you are receiving a multicast stream, change the 0.0.0.0 part to the multicast address of the stream)”
I’ve typed rtp://0.0.0.0:8888
I made everything the same as in that guide and when I’m trying to open http://[wowza-address]:1935/live/mpegts.stream/playlist.m3u8 in browser, it says that page not found.
Why is that? What I’ve done wrong? I’ve opened 1935 port and 8086 - is it necessary to open any other ports?
Original RTP stream is encoded with VLC and it’s H.264/AAC (RTP/MPEG Transport Team as destination).
Help me if somebody met with such case of using Wowza.
Thanks.

Thanks to everybody who helped me.
I’ve done it - with the guide I linked above, I recieve RPT/MPEG-TS packed stream with H.264/AAC and successfully re-stream it to iPhone app.
But there is one more thing - I have mistiming of sound and video. Sound has a delay in ~0.5-0.8 sec. It’s quite a big amount. Is there a way to avoid this?

Hi again. I’ve done with sound delay and now I’m going to approve my iPhone application.
I’m running media validator and it says that my playlist is wrong. Here are the warnings:
