[BUG] Bundled ffmpeg cannot find libav libraries - breaks GPU operations

[ohshitgorillas]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The bundled ffmpeg binary at /app/emby/bin/ffmpeg cannot locate its own libraries, causing GPU hardware acceleration to become unstable.

Running docker exec emby ldd /app/emby/bin/ffmpeg | grep "not found" shows:

	libavdevice.so.59 => not found
	libavfilter.so.8 => not found
	libavformat.so.59 => not found
	libavcodec.so.59 => not found
	libpostproc.so.56 => not found
	libswresample.so.4 => not found
	libswscale.so.6 => not found
	libavutil.so.57 => not found

Attempting to run ffmpeg directly produces:

docker exec emby /app/emby/bin/ffmpeg -version
/app/emby/bin/ffmpeg: error while loading shared libraries: libavdevice.so.59: cannot open shared object file: No such file or directory

The libraries exist in /app/emby/lib/ and /app/emby/extra/lib/ but are not in the dynamic linker's search path.

Workaround:

Add LD_LIBRARY_PATH=/app/emby/lib:/app/emby/extra/lib to container environment.

This workaround yields no results for the above "not found" search and the following when trying to execute ffmpeg:

Expected Behavior

ffmpeg should execute without library errors and Emby should be able to use hardware acceleration without requiring manual library path configuration.

Steps To Reproduce

1. Deploy container with GPU support using docker-compose (see below)
2. Run: docker exec emby ldd /app/emby/bin/ffmpeg | grep "not found"
3. Run: docker exec emby /app/emby/bin/ffmpeg -version
4. Observe the errors

It wasn't designed to support users running ffmpeg manually inside the container. Emby service already has that set:
https://github.com/linuxserver/docker-emby/blob/master/root/etc/s6-overlay/s6-rc.d/svc-emby/run#L5-L6

We do not support running manual commands inside the container unless they are listed in the readme.
