Any idea or suggestion regarding this issue?
Thanks
What player framework are you using? Are you seeing this issue in HLS.js, Shaka player or in the Native iOS AVPlayer?
That is pointing to the audio only AAC track at 128Kbps.
The other tracks appear to include video and audio, so I'm not sure without testing those on my own. Which I can't do unless you submit a support ticket through the Azure portal and include the details on your account and streaming endpoint. I suggest that path for faster support.

Google Action should play radio stream
I need to develop a Google Action which streams an audio/radio stream. i thought about media response. But the documentation says: "Audio for playback must be in a correctly formatted .mp3 file. Live streaming is not supported." Documentation Can someone give me an hint, what i have to do to stream an audio-stream? i found a german google action "baden fm" which streams their radio. But not sure how they do it. Kind Regards Stefan
The only ways to do this currently: Stream it in chunks of MP3 files, using the callback at the end of streaming to stream the next chunk Getting listed on TuneIn, Radio.com or iHeartRadio. From observation, Baden FM seems to be using TuneIn Through an App Action Use a Web site link that starts streaming via BrowseCarousel or Button Last 2 options are not helpful if you're going after non-browser-enabled devices. Also saw this thread which has some insight on MP3 size/duration: How can I tell Actions on Google to stream audio?
Google Actions do not currently support live audio streaming. I'm in contact with them but it seems they have no ETA to support this.
I was successful doing so with an mp3 live stream: NPR: https://npr-ice.streamguys1.com/live.mp3?ck=1597372625378 but not with mpd BBC test stream: https://rdmedia.bbc.co.uk/dash/ondemand/testcard/1/client_manifest-audio.mpd or with the HLS that my company uses ( .m3u8, can't publish the link publicly ) Note: added links as text/code since I'm not sure whether their companies policies are cool with them being indexed.
Nest Camera Video Streaming in VLC player
I have got a public share nest camera address from my friend. Instead of using a web browser for seeing the video, I want to use a VLC player to video stream. This way allows me to use many other features of VLC to do video analytics on the video. How to do it?
I was able to do this in these steps: Go to the public video share URL. It should be something like this:http://video.nest.com/live/pSgnOZ0s4t If you use developer tool on chrome and see network traffic ....look for a URL with .m3u8 in the end... it will be something like this:https://stream-delta.dropcam.com/nexus_aac/37451e60aeac457f9800704f1662147e/playlist.m3u8 Once you get that open that file in a text editor....you will get something like this inside the file #EXTM3U #EXT-X-VERSION:3 #EXT-X-STREAM-INF:BANDWIDTH=400816,CODECS="avc1.77.31,mp4a.40.2",RESOLUTION=1280x720 chunklist_w391480529.m3u8 The stream URL is then https://stream-delta.dropcam.com/nexus_aac/37451e60aeac457f9800704f1662047e/chunklist_w391480529.m3u8 Once you have this then install livestreamer to extract video like this: livestreamer "hls://https://stream-delta.dropcam.com/nexus_aac/37451e60aeac457f9800704f1662047e/chunklist_w391480509.m3u8" best -o nest_video.ts This will save the file to your disk. I used this to avoid nest aware subscription. Unfortunately, they charge so much for that service. When someone can just save the video to a disk and upload to a cheap cloud option...
I wrote a page that takes a public Nest video url and returns an HLS media .m3u8 streaming url get media url for nest/ dropcam cameras
How do I stream an uploaded video on Azure Media Services
I uploaded a video to Azure Media Services, and clicked the "publish" button. That gave me a publish URL. I then used the Azure Media Player (http://amp.azure.net/libs/amp/latest/docs/samples.html) to embed my video content on a page. The problem I'm having is that the video is choppy to start. Perhaps it's the encoding of the video, but I want to make sure, if I want to stream a video, using the media player or anything else, do I just use the "Publish URL"? OR is there a different way of requesting video content to "smooth stream"?
Yes. You use the publish URL for VOD and you have a few url parameters to change the type of streaming if needed. Default is smooth streaming. Smooth Streaming {streaming endpoint name-media services account name}.streaming.mediaservices.windows.net/{locator ID}/{filename}.ism/Manifest HLS Streaming {streaming endpoint name-media services account name}.streaming.mediaservices.windows.net/{locator ID}/{filename}.ism/Manifest(format=m3u8-aapl) MPEG Dash Streaming {streaming endpoint name-media services account name}.streaming.mediaservices.windows.net/{locator ID}/{filename}.ism/Manifest(format=mpd-time-csf) See what works best for you You can also test on this page and try the advanced settings http://amsplayer.azurewebsites.net/azuremediaplayer.html
The Azure Media Services test page has changed since the last post. The new URL is: https://ampdemo.azureedge.net/azuremediaplayer.html
How to play realtime binary stream through client speakers in HTML5
I need help playing a binary stream to a client's speakers using the client's web browser. The stream is being recorded from a client's web browser and is sent to a NodeJS server using BinaryJS. I have successfully streamed the binary data back to the client from the server, but cannot figure out how to play it. I am using NodeJs, BinaryJS, webAudio API, and HTML5. I have also been testing with Firefox. Has anybody done this before? Thanks in advance.
If this is an option for you, the simplest option would be to encode your data to a compressed format (say, mp3, ogg, opus, etc.), and simply put the URL in an <audio> tag. This pages is a good introduction on how to stream mp3 from node.
Will the chromecast play media segment files (.ts) from an m3u8 playlist?
I've noticed a lot of websites use m3u8 playlists on their html5 video tags, and those segment files inside the playlist appear to be h264 encoded, so I'm guessing the container is the only thing that the chromecast doesn't support in this case although I know very little about video containers and codecs so I'm probably just making no sense. So with all this in mind, is there any chance the chromecast will one day play those files? Here is an example http://stream.gravlab.net/003119/sparse/v1d30/posts/2014/barcelona/barcelona.m3u8 Thanks.
Yes - You can using either the default Receiver, a Styled Receiver, or in a Custom Receiver and using the Media Player Library. Of course, you (the owner of the data) must turn on CORS headers for the m3u8 manifest, any sub-manifests, and for the segments and any keys on your server / CDN to support this. This requirement is due to our player being written in JavaScript and running in Chrome on the Chromecast device. Note - for the Default Receiver & Styled Receiver, the URL to allow CORS from is www.gstatic.com. For your Custom Receiver, it will be the URL where you host your Receiver.
