[Fix] Roku Live TV broken on Apple Silicon Docker (linuxserver/emby ARM64)

[shiz504 0]

I’m a Premiere subscriber running linuxserver/emby on a Mac mini M4 in Docker. Roku Live TV was broken. Some channels played, others buffered or went black. No pattern.

Found the root cause. Two problems.

The linuxserver container’s LD_LIBRARY_PATH poisons Emby’s bundled ffmpeg on ARM64 at runtime. And Roku’s HLS client chokes on copy-codec passthrough for certain IPTV streams.

The fix. Wrapper scripts via custom-cont-init.d that clean the environment before ffmpeg launches and selectively rewrite copy-codec live streams to libx264/aac. ffdetect stays untouched. IsEmbyCustom stays true. No binaries modified. Persists across restarts.

Tested on:

- Emby 4.9.3.0
- linuxserver/emby:latest ARM64
- Docker Desktop 29.2.1
- macOS 26.3.1
- Mac mini M4
- Roku Streambar SE

Results: Five encoders detected. Zero errors. HLS confirmed on multiple live channels. Copy codec rewrite verified in logs.

Drop-in fix. Three minutes to install. Clone the repo, copy the scripts, add one mount line to your compose file, restart.

Happy to help anyone hitting the same issue.
