Reduce playing audio latency

Hi, I'm currently trying to convert an incoming audio stream (mulaw) to raw opus bitstream. Using ffmpeg and inputType as raw, I'm able to achieve it, but that introduces 3s of latency. Unfortunately, the incoming stream is real-time data, so this latency has to be reduced. I did manipulate around with ffmpeg, and got it to play a quiet popping noise under 1s (ofc that only happens when the stream audio is very loud). Here's my current ffmpeg setup (which doesn't work). Is there anything else I need to transform in stream for it to work?

// receiveRawStream is the raw mulaw Buffer
ffmpeg(receiveRawStream)
        .inputOptions([
            "-f mulaw",
            "-ar 8000",
            "-ac 1"
        ])
        .outputOption([
            "-c:a libopus",
            "-f ogg",
            "-ar 48000",
            "-ac 2",
        ])
        .on("error", (err)=>{
            console.log(err);
        })
        .pipe(new opus.OggDemuxer(), {end: false}) // The demuxer is from "prism-media" package
        .pipe(receiveffmpegStream);
/// receiveffmpegStream is the final stream before it's piped to createAudioResource (configured with StreamType.Opus)

// receiveRawStream is the raw mulaw Buffer
ffmpeg(receiveRawStream)
        .inputOptions([
            "-f mulaw",
            "-ar 8000",
            "-ac 1"
        ])
        .outputOption([
            "-c:a libopus",
            "-f ogg",
            "-ar 48000",
            "-ac 2",
        ])
        .on("error", (err)=>{
            console.log(err);
        })
        .pipe(new opus.OggDemuxer(), {end: false}) // The demuxer is from "prism-media" package
        .pipe(receiveffmpegStream);
/// receiveffmpegStream is the final stream before it's piped to createAudioResource (configured with StreamType.Opus)

Access internal network VPN

Currently, only one port can be forwarded by the service. In some cases, I want to access another port by the service to either test it or access its web management panel (i.e. rabbitMQ). Since internal network are just a virtual network made by wireguard, would it be possible to access it using the VPN client? Just curious if the VPN is setup in a way that this can be made possible.

Obtain git commit hash

Hey, I want to keep track of release version on the release file by using git hash, but railway's CI/CD system doesn't seem to to include .git directory during build process. Is there a way to pull the hash info without needing to run git clone (or calling github API)?

Clear dockerfile cache

Hi, I was trying to integrate sleep command before running the source for the internal DNS Resolver to setup. But it seems like it's still using the cached CMD command instead of the newly replaced ENTRYPOINT. Any ways to clear the cache?

mTLS Supported?

Hi, I just want to confirm this before implementing it. 1. Can you run an HTTPS server with an self-signed cert over the port (instead of HTTP)? 2. If so, will mTLS work properly over the proxied connection (i.e. client certificate auth)?
