I have every stream type enabled on my wowza server.
a week ago i had it working in the wowza test players
now the only one that works is the RTSP in VLC
now every stream just shows a black screen.
If i try to access the m3u8 via Safari browser i can hear the audio but no visual
Any assistance on this would be a major help.
this is due to incompatible video, audio codec. you need to user right encoder or you can use wowza transcoder to transcode your stream (h.264 , AAC) . it will resolve your playback problem. if you are using flash media live encoder you can select h.264 encoding method, and audio codec should be aac or mp3.
Some quick troubleshooting steps:
What source encoder are you using? Can you playback the source URL on VLC as well? What codec info is displayed in VLC for the source stream? It should be one of the supported codecs for Wowza.
What codec info is displayed in VLC for the RTSP playback link generated by your Wowza server?
Do you see any errors/warnings in the access log when you publish and playback your HLS (m3u8) stream?
Usually, this kind of error is due to an incorrect video codec, or an encoding setting, or network saturation where the video packets are not coming through correctly. You can check what error or warning messages are being generated by tailing the access log found in logs/ folder of your Wowza installation directory.
Hope this helps.

We generate RTSP stream (MP4 with ACC codec for audio) on our server and we need to send it to web app and play it.
We could send it via websocket and play it with media extensions but they are not supported on iOS.
We could also use WebRTC with media channel but that supports only Opus audio codec and we cannot afford transcoding from ACC to Opus.
Do you have any idea how can we play RTSP data on iOS devices?
EDIT: we aim for low latency playback (<1s) HSL has latency 5s+
you need to encode/package your stream in HLS on your server to send it to iOS clients. Try to look into FFMPEG streaming guides where the input is your RTSP stream and output is HLS. iOS really only plays HLS.
I'm recording screens and webcam video in a Chrome extension using WebRTC but it appears the audio streams in my .mp4 videos are encoded with Opus which causes QuickTime to display an Error -2048: Couldn't open the file video.mp4 because it is not a file that QuickTime understands.
Is it possible to use a different audio encoding option supported by Quicktime?
I don't believe mp4 supports any audio codecs supported by WebRTC.
If possible I would use Matroska, that supports VP8/VP9/H264 and Opus/PCM which will cover pretty much all WebRTC calls.
The Janus server is able to replay the RTP stream.
Is there a way to play a RTP stream directly into a video html5 element ?
(I don't really get the difference between RTP and RTSP)
And how can I play the RTP stream: should I transcode it to some HLS ?
You don't, it's not supported in HTML5. I'd recommend transcoding it to DASH and/or HLS, using either open source tools like ffmpeg or commercial solutions like bitmovin.
Webrtc is supported in HTML5, so you can view the video on the browser.
Janus Server supports different plugin for RTSP/RTP, which will receive data in RTSP/RTP and then send that data to the web browser client using webrtc.

I've successfully implemented the OpenTok. In group discussion (Three people, including moderator) video and audio transmission works well, but problem starts when moderator record stream. Video clip downloaded from OpenTok server has no sound.
Does anyone have any idea what can be wrong?
Thanks to Ankur (OpenTok Forum):
The audio stream in the downloaded videos is in the SPEEX codec. Many
desktop audio players don't recognize the codec. You may need to use
ffmpeg to transcode the audio before it is playable in programs like
VLC.
I have a live RTSP h.264 720p 8Mb stream that I need to get to my streaming provider's Flash Media Server. The only way that I currently have to stream to my provider's FMS is through Adobe's "Flash Media Live Encoder" Which works well enough with our SD analog capture card for live streaming.
I can open and re-stream the RTSP stream with VLC however VLC will not stream RTMP to the Flash Media Server.
Any thoughts on how to do this without going through the analog hole?
