Hello, i’m trying to stream with Apple HLS. I had no problems until i got a new source for my streaming files. I changed the origin URL of the Application. Now RTMP and other protocols working but Apple HLS not. How can i fix it? ---

Hi, When you say other protocols, which streaming protocols do you have in mind? Usually when one of the streaming protocols is working and another one isn’t, and the only thing that changed was the live stream/vod source, the first thing to look is in the encoding of that particular source. Since for the Apple HLS output, you need to have your source stream encoded in H264 video codec and AAC or MP3 audio codec, I would check if your source stream is using these codecs to encode the stream you are trying to deliver with Wowza.

Hi, Can you please open a support ticket by sending an email at support@wowza.com and describe the issue you are having. Make sure to add a reference to this forum post as well. Can also you create a ZIP archive containing your Wowza configuration and log files so we could take a closer look at your current setup and try to determine what might be wrong. Zoran ---

I’m using now RTMP and RTP, they are working well. Only Apple HLS output is not working. I just checked my source encoding, but it’s also encoded in H264/AAC. I don’t know what happened, i’ve 5 wowza-servers but HLS is working at none of them… ---
