I push via OBS, regular h264 stream to rtmp://ant.mydomain.com:1935/LiveApp/test

But if i want to play the RTSP stream : rtsp://ant.mydomain.com:5554/LiveApp/test, with ffplay or vlc, it crash the server

Environment

[] Operating system and version: Ubuntu 16.04.4 LTS [] Java version: openjdk version "1.8.0_181"

I also tried by directly subscribing to your ant media server using the Amazon webservice market place (ami-ef774904), and i noticed the very same behavior, so it doesn't seems to be related to a possible wrong installation.

Expected behavior

The RTSP to be displayed on VLC or ffplay, so my question, is RTSP supported by ant-media-server community edition ?

Actual behavior

code dumped.

More details

Idk if that would help anything but on this same server (ec2), i also tested red5pro, or https://github.com/iizukanao/node-rtsp-rtmp-server and RTSP streaming was working fine

Hi @steve-heslouin , Sorry for late reply.

Actually, we do not prefer to use RTSP for playing. We generally do not work about maintaining RTSP support. Because RTSP for playback is not preferred and there is no support in browser for that. Instead, WebRTC, which uses RTP for data transfer as in RTSP, is natively supported in browsers and we are working on WebRTC improvement.

Is there any specific reason for you to use RTSP for play back?

Regards, A. Oguz

Why we need RTSP is because lot of embedded kits does support only RTSP.

We are using TI CC3220 module with Omnivision OV788.

Please find the below document link of TI. http://www.ti.com/lit/an/swra599/swra599.pdf

Thanks.

Hi @kirantpatil, Thank you for your interest. We will notify you when we added RTSP stream feature.

mekya commented 5 years ago

Playing RTSP is not supported anymore. So that I'm closing this issue
