Handbrake-js on Heroku doesn't work.

[alexakuna]

Problem description:

Good afternoon. There is a problem. Using the npm install handbrake-js --save command, I installed handbrake-js as a library, and after some tweaking, handbrake-js started to do the job perfectly. And here's the problem. On the local computer everything works well, videos are decoded, etc. BUT (!) When I upload my application to Heroku, handbrake-js stops working.

HandBrake version:

5.0.2

Operating system and version:

macOS 10.15 Catalina

My application uses node js

Error message text:

Here is what information Heroku gives when deploy an application on Heroku:

Linux users handbrake-cli must be installed separately as the root user.

Ubuntu users can do this using the following commands: add-apt-repository --yes ppa: stebbins / handbrake-releases apt-get update -qq apt-get install -qq handbrake-cli

HandBrake Activity Log:

Here's what happens when you try to decode:

Here is the code used to set up and start decoding:

const options = {

        output: newPathVideo,
        preset: 'Gmail Medium 5 Minutes 480p30',
    }
    async function startEncoding () {
        console.log('Start decoding video')
        const result = await hbjs.run(options)
        console.log(`${result.stdout}End decoding video`)
    }
    await startEncoding()

I ask for help. How to solve this problem?

Handbrake-js is a javascript library which depends on HandbrakeCli being installed on the system. This error message is telling you that, on a Linux OS, HandbrakeCli must be installed manually as the root user using the follow commands.

add-apt-repository --yes ppa: stebbins / handbrake-releases
apt-get update -qq
apt-get install -qq handbrake-cli

You must run these commands as root yourself, npm install is not able to install linux packages as the root user.

Can I install handbrake-cli remotely?

I don't know - you need to ask Heroku.. i found this:
