Note: Before asking a question, please read the FAQ (Please read FAQ before filing an issue) #2716

Description

According to the official website documentation, I have installed SRS and used RTMP for streaming and WebRTC for playback. RTMP streaming is successful, and RTMP and FLV can be played back successfully. However, WebRTC cannot be played back. I have already modified the candidate to an external network address. Every time I click "Play Video", I get an error message saying "client disconnect peer. ret=1007"!

Previously, I followed the steps in the blog https://www.cnblogs.com/ziyue7575/p/13927894.html to install it four or five times without any issues. Please help me resolve this problem. Thank you.

Please describe the issue you are facing.

For the config srs.conf only enable live streaming and WebRTC, but doesn't enable the convert RTMP to WebRTC, vice versa. It's because the convert consumes lots of CPU, about 2% CPU for each stream, RTMP(aac) to WebRTC(opus), or WebRTC(opus) to RTMP(aac).

Please use config rtmp2rtc.conf, if convert RTMP to WebRTC, see Wiki: RTMP to RTC

Please use config rtc2rtmp.conf, if convert WebRTC to RTMP, see Wiki: RTC to RTC

For example:

./objs/srs -c rtmp2rtc.conf

Chinese Guide

Different configuration files must be used. Please refer to the content of the configuration for detailed differences. The main difference is that audio transcoding will not be automatically enabled due to high CPU consumption. Therefore, it must be explicitly enabled when converting between WebRTC and RTMP.

Please refer to the official website documentation for updated configuration information.

• For RTMP streaming and WebRTC playback, please use rtmp2rtc.conf. Refer to the Wiki: RTMP to RTC for more information.
• For WebRTC streaming and WebRTC playback, please use rtc2rtmp.conf. Refer to the Wiki: RTC to RTC for more information.

For example:

./objs/srs -c rtmp2rtc.conf

For example, RTMP streaming and FLV playback do not automatically enable RTC transcoding. If enabled, it can only support around 100 streams, but if not enabled, it can support around 3000 streams. Of course, enabling transcoding will have a significant impact on performance.

RTC streaming and RTC playback are the same, they will not be transcoded to RTMP by default.

So, have you solved your problem? I have also encountered such an issue.

Yes, I have solved it. The configuration file is not compatible between the new version and the old version. You just need to go and modify the "rtmp2rtc.conf" file under the "conf" directory. When starting, use the command "-c conf/rtmp2rtc.conf'".

It's resolved. The configuration files of the new version and the old version are not compatible. You can directly use the file "rtmp2rtc.conf" under the "conf" directory. When starting, use the command "-c conf/rtmp2rtc.conf".

This problem is too common. We have optimized the error message. If the RTMP stream already exists but the rtmp2rtc configuration is not enabled, playing WebRTC will result in a direct error.

RTC error code=5021 : Disabled rtmp_to_rtc of __defaultVhost__, see #2728
thread [35701][e7rc59t6]: do_serve_http() [src/app/srs_app_rtc_api.cpp:192][errno=35]

This allows errors to appear more quickly instead of having a black screen, as there are too many possibilities for a black screen. This obvious configuration issue should immediately result in an error to reduce troubleshooting time.

From a business logic perspective, if an RTMP stream has already been pushed, it is not possible to push another RTC stream with the same URL. Therefore, it must belong to the RTMP to RTC conversion scenario.

Note: RTC2RTMP does not perform this check because it is currently less commonly used.
