Please describe your expectation

Make sure to maintain the markdown structure. I'm trying to publish and play with webrtc in my flutter app. First I added the stream by OBV to server and I could play with VLCPlayer by rtmp. Even I could recieve it in webrtc in html default page of srs. Then I used some help from flutter_live project and rtcdn-draft to how play streams by webrtc. I received : no found valid H.264 payload type. Then I tried to publish my stream to server by webrtc from my app. I received again : no found valid H.264 payload type.

Is H5 OK? Or only issue in flutter_live?

Is H5 OK? Or only issue in flutter_live?

Yes H5 is Ok. I easily can publish Streams by OBV and play in H5(webrtc) and VlC-player (rtmp). But when I try to publish or play from flutter app I receive this error.

If H5 is ok, it generally the problem of client, and SRS can not help you.

Please check your client carefully.

BTW: Recommend use HTTP-FLV/RTMP/HLS if possible.

Dear Winlinvip, Thanks for your answer and help. I tried so much and I found something. When I'm using flutter-web. everything is ok. Peer Connection is ok and I can publish and play in both side. But when I'm trying on emulator or real device I receive this error : no valid found h264 payload type Don't you think it might be related to srs server or any config?

[Alijaaan]

Dear Winlinvip,

I've searched a lot in flutter webrtc and I found many devices are not support H264. It means if anyone wants to use webrtc in any device they have problem like me. That's why I could publish and play easily in flutter web, but no luck in device. Is there any chance to support other codecs in srs server or is there any configuration that I missed?

Thanks in advance for your time and help.
