MiroTalk SFU: Recording not possible?

[MiroTalk]

@nebulon @James @shrey

Implemented in MiroTalk SFU v2.0.14 — Docker image is building now (available in ~1 hour).

• Build

For Cloudron deployments, server-side recording should now work using the following configuration:

Recording

RECORDING_ENABLED=true
RECORDING_DIR='../data/rec'            # Path relative to /app/code → resolves to /app/data/rec
RECORDING_MAX_FILE_SIZE=1073741824     # Max file size in bytes (default: 1GB)

RTMP

RTMP_DIR='../data/rtmp'                # Path relative to /app/code → resolves to /app/data/rtmp

Note

If the target directories do not exist, MiroTalk SFU will automatically create them at runtime, just like before.

Cloudron automatically mounts /app/data, so using ../data/... ensures the app writes to the persistent, writable directory.

New package is out. Thanks for all the work @mirotalk-57bab571 and being so proactive here!

Good! I’m always here to help. Thanks to Cloudron for trusting MiroTalk and supporting us! By the way, I love the new Cloudron UI v.9.0.10, it looks amazing!

PS: Thanks also to @James for his IT support and excellent debugging and suggestions.

Hi @nebulon @mirotalk-57bab571
So, i'm still unable to boot up the app after setting RECORDING_ENABLED=true :

Forget the previous env configuration. In the latest Cloudron commit, recording is enabled by default, and the app/data path now appears to be automatically resolved as well.

I restarted the updated app, but i still get only this:

No rec folder available, and no default recording taking place.

@mirotalk-57bab571

It seems like 2 separate updated packages have been released for this.
Just came across the 2nd one and updated the app again.

1. The rec folder is now available in /app/data/
2. All recordings are still being saved on the local device only. No server-side recording. No S3 recording.

Hello @shrey
I have just updated my Mirotalk SFU app and now the recordings are stored inside the Mirotalk SFU app in /app/data/rec/.
Please share your /app/data/env file.
With the updated app and a fresh installed app the recording works.
In a meeting I can do:

ls -lah /app/data/rec/
total 5.2M
drwxr-xr-x 2 cloudron cloudron 4.0K Nov 15 09:46 .
drwxr-xr-x 3 cloudron cloudron 4.0K Nov 15 09:44 ..

Hi @james , thanks for the screenshots. I can now see that there's a "Save on server" option in the UI, and it's working for me as well.

Now, just S3 is left to work.
My env file ->

# Recording
RECORDING_ENABLED=true                           # Enable recording functionality (true|false)
RECORDING_UPLOAD_TO_S3=false                      # Upload recording to AWS S3 bucket [true/false]

# AWS S3 Configuration  
AWS_S3_ENABLED=true                              # Enable AWS S3 storage (true|false)  
AWS_S3_BUCKET_NAME=<bucket-name>                       # Name of your S3 bucket (must exist)  
AWS_ACCESS_KEY_ID=<key-id>                                # AWS Access Key ID (leave empty for IAM roles)  
AWS_SECRET_ACCESS_KEY=<key-secret>                            # AWS Secret Access Key (leave empty for IAM roles)  
AWS_REGION=<region>                                   # AWS region (e.g., us-east-2, eu-west-2)  
AWS_S3_ENDPOINT=https://<region>.digitaloceanspaces.com

Note: Although i didn't find the "AWS_S3_ENDPOINT" key in the env template, i configured it because it seems to work with most S3 client libraries, and is a necessity to be able to connect to S3 spaces other than AWS.

Hello @shrey
The library used in MiroTalk SFU for AWS/S3 is aws-sdk/client-s3.
It seems MiroTalk SFU does not have the option to configure the endpoint.
From the MiroTalk SFU Code handling the configuration:

https://github.com/miroslavpejic85/mirotalksfu/blob/b2a41e597610524b259097d2e1b52674dda631c0/app/src/config.template.js#L948-L954

        aws: {
            enabled: process.env.AWS_S3_ENABLED === 'true',
            accessKeyId: process.env.AWS_ACCESS_KEY_ID || 'your-access-key-id',
            secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY || 'your-secret-access-key',
            region: process.env.AWS_REGION || 'us-east-2',
            bucket: process.env.AWS_S3_BUCKET || 'mirotalk',
        },

Also in the server.js where the S3Client is initialized, the endpoint is never configured, thus using the default, resolving the endpoint from the AWS_REGION.
https://github.com/miroslavpejic85/mirotalksfu/blob/b2a41e597610524b259097d2e1b52674dda631c0/app/src/Server.js#L297-L303

const s3Client = new S3Client({
    region: config?.integrations?.aws?.region, // Set your AWS region
    credentials: {
        accessKeyId: config?.integrations?.aws?.accessKeyId,
        secretAccessKey: config?.integrations?.aws?.secretAccessKey,
    },
});

So we need to ask @mirotalk-57bab571 to add the option to configure the endpoint as well.
Adding to that, when a non AWS endpoint is used, the option forcePathStyle: true might also be needed for the best compatibility with e.g. MinIO and most S3-compatible systems.

@mirotalk-57bab571
It is the weekend, please don't feel pressured or forced to work on the weekend.
Would it be possible to add the option to configure the S3Client endpoint config and S3Client forcePathStyle config?
