After OBS Studio 29.1, they added support for Enhanced RTMP, it is now possible to push HEVC streaming via RTMP, and SRS also support HEVC over RTMP and HTTP-FLV v6.0.2+.
Here is a simple tutorial on how to use OBS to push HEVC streams to SRS.
OBS support H.265 over RTMP v29.1+
The original RTMP protocol cannot support high-compression video formats such as HEVC or AV1. But from OBS Studio 29.1 Beta, OBS adds support for the updated: Enhanced RTMP. For more detail, please refer to: Enable AV1, HEVC via RTMP to YouTube.
Therefore, the first step to push an HEVC stream via RTMP from OBS is to download the latest version of OBS. (Download here: OBS Studio 29.1 Beta Release Page).
