Can you change resolution in ant media?

Short description

I'm fairly new to ant media I have both community and enterprise, I tested my 4k and HD video stream on YouTube on both community and enterprise through the live app on ant media but the output quality is still at 360p, is there a way to change it, so that my output quality is higher? because I want to be able to stream in 4k.

Output of video to YouTube should be either 1080p or 2160p

Output is only coming out at 360p with adaptive streaming set

Hi @xxd4rkph0enix2
Have you configured ABR (adaptive streaming) on the enterprise edition? If ABR is not enabled, the server simply forwards the incoming stream to YouTube or any other RTMP end point.
Following that, YouTube converts it into various bit rates.

Thank you for the reply, yes I went into settings under live app and selected 2160p as resolution and 9000kbps as bitrate, I have also tried changing bitrate but when I test my stream and view it, it doesn't show quality any higher than 360p.

@xxd4rkph0enix2
Ok try as follows:

1. Remove the bit rate on the server side.
2. Send the stream with 1080p or 4K on the server directly and then watch it on the YouTube. On YouTube you will get multiple bit rates to play.

As I mentioned, in this case server will forward your stream as it is on the YouTube.

Hi I'm not getting any bitrates displayed the broadcast status keeps going offline, so it just buffers with no image on YouTube side, am I missing something? sorry to be a bother.

Hi @xxd4rkph0enix2

Have you tried with the bandwidth : "unlimited" and video width height like 1280:720 in the JS SDK ?

@xxd4rkph0enix2
Could you please let us know that how are you publishing the stream on Ant Media Server? Is it RTMP, WebRTC, Playlist or any other stream source?

[xxd4rkph0enix2]

Hi sorry have no idea what JS SDK would you mind explaining? my video is in 4K that I want to stream for 24/7 its just not giving 4k as an option for quality on YouTube side

[xxd4rkph0enix2]

I am publishing my mp4 3840p x 2160p video through Live app playlist.

@xxd4rkph0enix2 Please share the reproducible scenario (How you are trying). The way we can better understand.

[xxd4rkph0enix2]

I created a video in premier pro which I exported in 4K, which is a mp4 I already had a linode Ant media Server which was community, so I just created a new Ant Media Enterprise Server in linode from there I signed into Ant Media and created a playlist in Live App, I then went to VOD and uploaded my 4k mp4 file, I took the VOD ID and went to edit playlist and created the URL and saved it. I then went to settings and enabled adaptive streaming where I selected 2160p and 9000kbps which my husband told me was the correct kbps and then clicked save. Then I went to start stream, and I had it set up on YouTube that my husband could view on his end to check if it was outputting the quality at 4k or at least giving the option to view it in 4k but it was only giving the option of 360p.

There are different SDK available in antmedia github repository for building applications on different platform (Android, IOS, WEB). JS SDK is one of them, using which developer used to create webRTC based application (Interaction using browsers). But in your case it seems you are using rtmp protocol for publishing the stream to youtube (So its not useful for you).

[xxd4rkph0enix2]

Ok thank you, is there a different way or solution to getting 4k output quality for my stream?

@xxd4rkph0enix2 just to reiterate on what yash said earlier, your bottleneck could be on the settings you selected on server when setting up the playlist.

 

1. make sure you are able to play the stream through ant media server locally. Then you will know the stream works.

2. for YouTube you have be sure that the encoding, audio etc are as per YouTube requirements. 

3. without abr setting once and see if the stream plays locally and on YouTube.

4. try a lower quality version of the file you created in the playlist and see if that works.
