Plan to release the SRS 6.0 beta version.

I had planned to release SRS 6.0 at the end of 2024, but the release was delayed due to my travel to Canada and starting work there. Therefore, I think it is possible to release it at the end of 2025.

The major changes in SRS 6.0 are HEVC and SmartPointers, as listed below:

• Supports HEVC encoding format, including protocols like RTMP, HTTP-FLV, HTTP-TS, HLS, and SRT. #465
• Uses smart pointers (SrsUniquePtr and SrsSharedPtr) to improve memory management and fixes multiple memory leak issues. #4089, #4109
• Supports IP whitelisting for HTTP-FLV, HLS, WebRTC, and SRT. #3902
• Added Basic Authentication feature for HTTP API. #3458
• GB28181 protocol supports external SIP servers. #4101, srs-sip

For SmartPointers, we created a very simple subset of C++11 smart pointers, because the C++11 implementation is complicated and difficult to understand. Rather than true smart pointers, what we have is only automatic memory management, as we do not support many features of smart pointers. We found it quite straightforward and easy to maintain after several months of working with smart pointers.

Regarding HEVC, we have implemented almost all major features, including RTMP with the enhanced RTMP protocol, SRT, and HLS via the MPEGTS protocol, WebRTC for Safari, as well as MPEG-DASH and DVR via MP4. However, Chrome did not support HEVC until a few months ago, so WebRTC HEVC support for Chrome is available in SRS 7.0, but not in SRS 6.0. And, HLS via fMP4 will be supported in SRS 7.0; however, keep in mind that only HLS via MPEGTS is supported in SRS 6.0.

In fact, we finished the last major feature in July 2024 and released alpha version 0, which means we have frozen features and begun fixing bugs for SRS 6.0.

• 2025-05-03, Release v6.0-a2, v6.0-a2, 6.0 alpha2, v6.0.165, 169712 lines.
• 2024-09-01, Release v6.0-a1, v6.0-a1, 6.0 alpha1, v6.0.155, 169636 lines.
• 2024-07-27, Release v6.0-a0, v6.0-a0, 6.0 alpha0, v6.0.145, 169259 lines.

After releasing three alpha versions, we have significantly improved stability and are now ready to release the beta versions. I suppose there may be a few beta versions by the end of 2025, after which we will release the first official version of SRS 6.0.

I do not pledge to finish the work, but it is potentially achievable.
