demux SPS/PPS : avc decode sequence header

[tianyi14]

Note: Please read FAQ before file an issue, see #2716

Description

On my side, I am using C++ to encode and push the stream. I want to know where the problem is with the error message from SRS. Is it missing the SPS (Sequence Parameter Set) or is there an extra one (seems to have no impact, as I have already fixed it before)?

Expect

The streaming is expected to be error-free.

if (!stream->require(6)) { return srs_error_new(ERROR_HLS_DECODE_ERROR, "avc decode sequence header"); } I found that the exception was thrown here. I set parse_sps off in the configuration file to disable SPS parsing. Why is it still happening like this?

@tianyi14 you how to resolve the problem? I have the same problem

1. Can the issue be reproduced? Please provide a detailed description of the steps to reproduce the problem, and if possible, upload the test file.
2. Is there a core dump file available?
