Description

livekit==1.1.3 fails to load liblivekit_ffi.so when running in a linux/arm64 Docker container based on Debian Bookworm (python:3.11-slim-bookworm). The native library references __arm_tpidr2_save, which is not available in the Bookworm glibc.

This is the same class of issue as AGT-2075 (glibc symbol incompatibility), but with a different symbol on arm64.

Environment

• Host: macOS on Apple Silicon (arm64)
• Docker image: python:3.11-slim-bookworm (linux/arm64)
• livekit version: 1.1.3
• livekit-agents version: 1.5.1

Error

File "/workspace/.venv/lib/python3.11/site-packages/livekit/rtc/_ffi_client.py", line 228, in __init__
    raise ImportError(
ImportError: failed to load liblivekit_ffi.so:
/workspace/.venv/lib/python3.11/site-packages/livekit/rtc/resources/liblivekit_ffi.so: undefined symbol: __arm_tpidr2_save
Install the livekit package with: pip install livekit
Or set LIVEKIT_LIB_PATH to the path of the native library.

Steps to reproduce

1. On an Apple Silicon Mac, build a Docker image using python:3.11-slim-bookworm as base (defaults to linux/arm64)
2. Install livekit==1.1.3
3. Import livekit or run any command that triggers FfiClient initialization

Workaround

Building with --platform linux/amd64 (x86 emulation via Rosetta) avoids the issue.
