RTMP: Pushing stream failed, indicating decode SPS.

[dft2000]

Streaming failed. Every time I try to stream, it reports a parsing SRS error and exits directly. I also tried turning off parse-srs, but it still gives the same error. Thank you.

Please describe the issue you are facing.

1. SRS version: 3.0.156

In the bug, it is mentioned that the file is test.flv, but the uploaded file is in mp4 format. Can you confirm if we can use this mp4 file to reproduce the issue?

If we can reproduce the issue, it might be due to a specific problem with the stream. Please confirm if it can be reproduced, as it will help in resolving the issue faster.

If it can be reproduced, it may be due to a special issue with the stream. Please confirm if it can be reproduced, as it will help resolve the problem faster.

It can be reproduced. This MP4 file is just a re-encapsulation of the test.flv. I have tested and obtained the same results.

In the provided file, there are 2 SPS (Sequence Parameter Set) in avcC. The function part of SRS that parses SPS needs to be made compatible.

Reference a0c09d8, you can try merging and testing it yourself.

However, there is a hidden danger:
Although your file has 2 sps/pps, the content is the same, so you can choose either one. If you encounter 2 different sps, I am not sure how to choose. If you have any related documents, please send them over for reference.
