Replay(重现)
手机端开启旋转功能，旋转后视频录制立刻中断

如果视频发生了无法录制在一个文件的情况，请重新创建一个新的文件进行录制
In addition, there are situations where the recording is interrupted due to an inability to determine the source of the problem.

Among them, there were numerous errors like RTC: Drop for ssrc. Due to their frequent occurrence, some of them were removed from the above log to avoid confusion.
I can confirm that there was no rotation occurring here (because I am using a PC browser).

Here, I hope that if there is an error during video recording
-
Save the existing data and stop recording the current file.
-
Attempt to restart recording, and if recording can be started, save it to a file.
-
(If recording fails, it is best to keep a failed file until recording is successfully restarted.)

WebRTC recording is a challenge, this thing often changes sps/pps.
If HLS is working properly, you can consider using on_hls for recording. For more details, please refer to https://github.com/ossrs/srs/issues/1577.

I haven't tried HLS yet, but I feel that the more complex it is, the more likely it is to have issues. I think it would be more stable to save WebRTC as webm, taking reference from open-source codes like Google Chrome browser.

Changing the resolution during webrtc recording does indeed cause the DVR recording to fail. I have looked into the recording documentation for HLS and configured hls_cleanup to be off, which prevents the deletion of ts files. However, it seems that the m3u8 file cannot save all the ts information completely and may delete old ones based on the configuration rules. I noticed that srs-cloud seems to be able to do this. How can I configure it to save the complete m3u8 file? I would like to use this to solve the recording issue.
