## Remote Tools

You need at least 512MB RAM to run the script.
Scripts can be launched directly from a PeerTube server, or from a separate server, even a desktop PC.
You need to follow all the following steps even if you are on a PeerTube server (including cloning the git repository in a different directory than your production installation because the scripts utilize non-production dependencies).

### Dependencies

Install the [PeerTube dependencies](dependencies.md) except PostgreSQL and Redis.

### Installation

Clone the PeerTube repo to get the latest version (even if you are on your PeerTube server):

```bash
$ git clone https://github.com/Chocobozzz/PeerTube.git
$ CLONE="$(pwd)/PeerTube"
$ cd ${CLONE}
```

Install dependencies and build CLI tools:

```bash
$ NOCLIENT=1 yarn install --pure-lockfile
$ npm run setup:cli
```

### CLI wrapper

The wrapper provides a convenient interface to the following scripts.
You can access it as `peertube` via an alias in your `.bashrc` like `alias peertube="cd /your/peertube/directory/ && node ./dist/server/tools/peertube.js"` (you have to keep the `cd` command):

```
  Usage: peertube [command] [options]

  Options:

    -v, --version         output the version number
    -h, --help            output usage information

  Commands:

    auth [action]         register your accounts on remote instances to use them with other commands
    upload|up             upload a video
    import-videos|import  import a video from a streaming platform
    watch|w               watch a video in the terminal ✩°｡⋆
    repl                  initiate a REPL to access internals
    plugins|p [action]    manage instance plugins
    redundancy|r [action] manage video redundancies
    help [cmd]            display help for [cmd]
```

The wrapper can keep track of instances you have an account on. We limit to one account per instance for now.

```bash
$ peertube auth add -u 'PEERTUBE_URL' -U 'PEERTUBE_USER' --password 'PEERTUBE_PASSWORD'
$ peertube auth list
┌──────────────────────────────┬──────────────────────────────┐
│ instance                     │ login                        │
├──────────────────────────────┼──────────────────────────────┤
│ 'PEERTUBE_URL'               │ 'PEERTUBE_USER'              │
└──────────────────────────────┴──────────────────────────────┘
```

You can now use that account to upload videos without feeding the same parameters again.

```bash
$ peertube up <videoFile>
```

And now that your video is online, you can watch it from the confort of your terminal (use `peertube watch --help` to see the supported players):

```bash
$ peertube watch https://peertube.cpy.re/videos/watch/e8a1af4e-414a-4d58-bfe6-2146eed06d10
```

To list, install, uninstall dynamically plugins/themes of an instance:

```bash
$ peertube plugins list
$ peertube plugins install --path /local/plugin/path
$ peertube plugins install --npm-name peertube-plugin-myplugin
$ peertube plugins uninstall --npm-name peertube-plugin-myplugin
```

#### peertube-import-videos.js

You can use this script to import videos from all [supported sites of youtube-dl](https://rg3.github.io/youtube-dl/supportedsites.html) into PeerTube.
Be sure you own the videos or have the author's authorization to do so.

```sh
$ node dist/server/tools/peertube-import-videos.js \
    -u 'PEERTUBE_URL' \
    -U 'PEERTUBE_USER' \
    --password 'PEERTUBE_PASSWORD' \
    --target-url 'TARGET_URL'
```

* `PEERTUBE_URL` : the full URL of your PeerTube server where you want to import, eg: https://peertube.cpy.re
* `PEERTUBE_USER` : your PeerTube account where videos will be uploaded
* `PEERTUBE_PASSWORD` : password of your PeerTube account (if `--password PEERTUBE_PASSWORD` is omitted, you will be prompted for it)
* `TARGET_URL` : the target url you want to import. Examples:
  * YouTube:
    * Channel: https://www.youtube.com/channel/ChannelId
    * User https://www.youtube.com/c/UserName or https://www.youtube.com/user/UserName
    * Video https://www.youtube.com/watch?v=blabla
  * Vimeo: https://vimeo.com/xxxxxx
  * Dailymotion: https://www.dailymotion.com/xxxxx

The script will get all public videos from Youtube, download them and upload to PeerTube.
Already downloaded videos will not be uploaded twice, so you can run and re-run the script in case of crash, disconnection...

Videos will be publicly available after transcoding (you can see them before that in your account on the web interface).

**NB**: If you want to synchronize a Youtube channel to your PeerTube instance (ensure you have the agreement from the author),
you can add a [crontab rule](https://help.ubuntu.com/community/CronHowto) (or an equivalent of your OS) and insert
these rules (ensure to customize them to your needs):

```
# Update youtube-dl every day at midnight
0 0 * * * /usr/bin/npm rebuild youtube-dl --prefix /PATH/TO/PEERTUBE/

# Synchronize the YT channel every sunday at 22:00 all the videos published since last monday included
0 22 * * 0 /usr/bin/node /PATH/TO/PEERTUBE/dist/server/tools/peertube-import-videos.js -u '__PEERTUBE_URL__' -U '__USER__' --password '__PASSWORD__' --target-url 'https://www.youtube.com/channel/___CHANNEL__' --since $(date --date="-6 days" +%Y-%m-%d)
```

Also you may want to subscribe to the PeerTube channel in order to manually check the synchronization is successful.

#### peertube-upload.js

You can use this script to import videos directly from the CLI.

Videos will be publicly available after transcoding (you can see them before that in your account on the web interface).

```bash
$ cd ${CLONE}
$ node dist/server/tools/peertube-upload.js --help
```

#### peertube-watch.js

You can use this script to play videos directly from the CLI.

It provides support for different players:

- ascii (default ; plays in ascii art in your terminal!)
- mpv
- mplayer
- vlc
- stdout
- xbmc
- airplay
- chromecast


#### peertube-plugins.js

Install/update/uninstall or list local or NPM PeerTube plugins:

```bash
$ cd ${CLONE}
$ node dist/server/tools/peertube-plugins.js --help
$ node dist/server/tools/peertube-plugins.js list --help
$ node dist/server/tools/peertube-plugins.js install --help
$ node dist/server/tools/peertube-plugins.js update --help
$ node dist/server/tools/peertube-plugins.js uninstall --help

$ node dist/server/tools/peertube-plugins.js install --path /my/plugin/path
$ node dist/server/tools/peertube-plugins.js install --npm-name peertube-theme-example
```

#### peertube-redundancy.js

Manage (list/add/remove) video redundancies:

To list your videos that are duplicated by remote instances:

```bash
$ node dist/server/tools/peertube.js redundancy list-remote-redundancies
```

To list remote videos that your instance duplicated:

```bash
$ node dist/server/tools/peertube.js redundancy list-my-redundancies
```

To duplicate a specific video in your redundancy system:

```bash
$ node dist/server/tools/peertube.js redundancy add --video 823
```

To remove a video redundancy:

```bash
$ node dist/server/tools/peertube.js redundancy remove --video 823
```

## Server tools

These scripts should be run on the server, in `peertube-latest` directory.

### parse-log

To parse PeerTube last log file:

```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run parse-log -- --level info
```

`--level` is optional and could be `info`/`warn`/`error`

You can also remove SQL or HTTP logs using `--not-tags`:

```
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run parse-log -- --level debug --not-tags http sql
```

### create-transcoding-job.js

You can use this script to force transcoding of an existing video. PeerTube needs to be running.

To generate transcoding jobs depending on the instance configuration:
```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run create-transcoding-job -- -v [videoUUID]
```

Or to transcode to a specific resolution:
```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run create-transcoding-job -- -v [videoUUID] -r [resolution]
```
The resolution should be an integer (`1080`, `720`, `480`, etc.)

To generate an HLS playlist for a video:

```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run create-transcoding-job -- --generate-hls -v [videoUUID]
```

### create-import-video-file-job.js

You can use this script to import a video file to replace an already uploaded file or to add a new resolution to a video. PeerTube needs to be running.

```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run create-import-video-file-job -- -v [videoUUID] -i [videoFile]
```

### prune-storage.js

Some transcoded videos or shutdown at a bad time can leave some unused files on your storage.
Stop PeerTube and delete these files (a confirmation will be demanded first):

```bash
$ cd /var/www/peertube/peertube-latest
$ sudo systemctl stop peertube && sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run prune-storage
```

### optimize-old-videos.js

Before version v1.0.0-beta.16, Peertube did not specify a bitrate for the
transcoding of uploaded videos. This means that videos might be encoded into
very large files that are too large for streaming. This script re-transcodes
these videos so that they can be watched properly, even on slow connections.

```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run optimize-old-videos
```


### update-host.js

**Changing the hostname is unsupported and may be a risky operation, especially if you have already federated.**
If you started PeerTube with a domain, and then changed it you will have
invalid torrent files and invalid URLs in your database. To fix this, you have
to run the command below (keep in mind your follower instances will NOT update their URLs).

```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run update-host
```

### reset-password.js

To reset a user password from CLI, run:

```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run reset-password -- -u target_username
```


### plugin install/uninstall

The difference with `peertube plugins` CLI is that these scripts can be used even if PeerTube is not running.
If PeerTube is running, you need to restart it for the changes to take effect (whereas with `peertube plugins` CLI, plugins/themes are dynamically loaded on the server).

To install/update a plugin or a theme from the disk:

```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run plugin:install -- --plugin-path /local/plugin/path
```

From NPM:

```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run plugin:install -- --npm-name peertube-plugin-myplugin
```

To uninstall a plugin or a theme:

```bash
$ cd /var/www/peertube/peertube-latest
$ sudo -u peertube NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run plugin:uninstall -- --npm-name peertube-plugin-myplugin
```

### REPL (Read Eval Print Loop)

If you want to interact with the application libraries and objects even when PeerTube is not running, there is a REPL for that.

usage: `node ./dist/server/tools/peertube-repl.js`

"The default evaluator will, by default, assign the result of the most recently evaluated expression to the special variable `_` (underscore). Explicitly setting `_` to a value will disable this behavior."

- type `.help` to list commands available in the repl, notice it starts with a dot
- type `.exit` to exit, note that you still have to press CTRL-C to actually exit, or press CTRL-C (3 times) without typing `.exit` to exit
- type `context` to list all available objects and libraries in the context, note: `Promise` is also available but it's not listed in the context, in case you need promises for something
- type `env` to see the loaded environment variables
- type `path` to access path library
- type `lodash` to access lodash library
- type `uuidv1` to access uuid/v1 library
- type `uuidv3` to access uuid/v3 library
- type `uuidv4` to access uuid/v4 library
- type `uuidv5` to access uuid/v5 library
- type `YoutubeDL` to access youtube-dl library
- type `cli` to access the cli helpers object
- type `logger` to access the logger; if you log to it, it will write to stdout and to the peertube.log file
- type `constants` to access the constants loaded by the server
- type `coreUtils` to access the core-utils helpers object
- type `ffmpegUtils` to access the ffmpeg-utils helpers object
- type `peertubeCryptoUtils` to access the peertube-crypto helpers object
- type `signupUtils` to access the signup helpers object
- type `utils` to access the utils helpers object
- type `YoutubeDLUtils` to access the youtube-dl helpers object
- type `sequelizeTypescript` to access sequelizeTypescript
- type `modelsUtils` to access the models/utils
- type `models` to access the shortcut to sequelizeTypescript.models
- type `transaction` to access the shortcut to sequelizeTypescript.transaction
- type `query` to access the shortcut to sequelizeTypescript.query
- type `queryInterface` to access the shortcut to sequelizeTypescript.queryInterface
