HEVC Ingest via RTMP does not work

[MatisOne]

Describe the bug
Streaming via OBS Studio using the HEVC video codec, OME claims that it does not support this codec. This may be similar to #900 but OME does not crash, it just sends the error to the log file with a very precise line where the error occurred.

To Reproduce
Steps to reproduce the behavior:

1. Set Server.xml for basic RTMP input and LLHLS output for example: my Server.xml
2. Setup OBS Studio 31.0.0 to use RTMP and HEVC
3. Start streaming and see the error

Expected behavior
Ingesting video in HEVC via RTMP works without problems because ingesting HEVC via SRT protocol just works

rtmp protocol does not support HEVC by design. it is part of enhanced rtmp protocol.

any updates?

RTMP does not support HEVC. However, Enhanced-RTMP was recently released, and it supports HEVC. OME is planning to support it in 2025. See our 2025 Roadmap.
