Welcome to django-vidar

The purpose? To archive youtube videos from Channels and Playlists based on cron-like scheduling.

Current State? Well, it works with my current django setup. There is a demo available using the Docker Demo section below.

Requirements

You will need to use django v5.1.0 or greater as the template files make use of the querystring templatetag.

I develop and run my site on postgresql 15, the tests all run on the same version 15. I've tried running the tests on sqlite and some fail due to true/false type differences related to user watch history and its calculations.

Python:

django>=5.1
django-bootstrap4
django-celery-beat
django-celery-results
django-environ
django-mathfilters
django-positions
django-mptt
celery
redis
requests
beautifulsoup4
yt-dlp
moviepy
Pillow>=10.0.0

HTML/JS/CSS:

htmx
jquery
jqueryui
popper.js

bootstrap 4
pickadate.js - https://amsul.ca/pickadate.js/
font-awesome

Installation

Current installation method assumes you already have a django project to add vidar too.

Install django-vidar:

pip install https://github.com/django-vidar/django-vidar/archive/refs/heads/master.zip

Add the following to your settings INSTALLED_APPS:

INSTALLED_APPS = [
    ....
    'vidar',
    'django.contrib.humanize',
    'bootstrap4',
    'celery',
    'django_celery_results',
    'django_celery_beat',
    'mathfilters',
    'mptt',
    ...
]

Demo

In the repo you will find a docker-compose.yml you can test Vidar with.

I primarily work on Windows based machines and the current compose file has worked on Windows 10 and 11 using Docker Desktop.

To run the demo:

git clone https://github.com/django-vidar/django-vidar.git
cd django-vidar
docker compose up -d

You can login at http://127.0.0.1:8000 using username vidar and password vidar.

Any media downloaded in the demo will be stored within ./cache/media/ of the repo directory.

If for some reason you don't want to use the celery images, remove them from docker-compose.yml and change CELERY_TASK_ALWAYS_EAGER=False to True. The celery based tasks will run within the confines of the web request, your page view will stall while things happen.

Celery

If you do not already have celery setup, you will also need to follow the Celery with Django instructions.

django-vidar assigns its tasks to 2 different queues, one named queue-vidar and queue-vidar-processor

queue-vidar is the primary queue. Checking channels, playlists, downloading videos..etc happens here.
queue-vidar-processor is the secondary queue where video and audio conversion happens.

I would recommend running queue-vidar-processor on its own worker and with concurrency of 1 as the video conversion uses all cores and hammering the CPU can make things take longer. This is also why the separation of queues exists. I do not want video conversion interfering with checking of channels for new videos. See docker below for example commands.

For simplicity sake I will include the bare minimum changes necessary to make celery work with a django project. You will need to replace myproj with whatever your project is called.

myproj/__init__.py:

from __future__ import absolute_import, unicode_literals

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celery import app as celery_app


__all__ = ["celery_app"]

myproj/celery.py:

from __future__ import absolute_import, unicode_literals

import os

from celery import Celery

# set the default Django settings module for the 'celery' program.
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproj.settings")

app = Celery("myproj")

# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
#   should have a `CELERY_` prefix.
app.config_from_object("django.conf:settings", namespace="CELERY")

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()

Docker

You will need to run beat and 1 or 2 other workers.

Some helpful commands:

# Run beat
celery -A myproj beat --loglevel=INFO
celery -A myproj worker -Q queue-vidar --loglevel INFO --prefetch-multiplier 1
celery -A myproj worker -Q queue-vidar-processor --concurrency 1 --loglevel INFO --prefetch-multiplier 1

# If you want to run both queues on a single worker, just combine -Q like such
celery -A myproj worker -Q queue-vidar,queue-vidar-processor --loglevel INFO --prefetch-multiplier 1

Jellyfin

I use Jellyfin with a plugin called YouTubeMetadata

The following configurations and their default values are required for the plugin to work.

VIDAR_CHANNEL_DIRECTORY_SCHEMA
VIDAR_SAVE_INFO_JSON_FILE
VIDAR_VIDEO_DIRECTORY_SCHEMA
VIDAR_VIDEO_FILENAME_SCHEMA

redis messaging

As Vidar tasks are processing various things they can send messages to the frontend indicating what is happening.

Things like a channel or a playlist being indexed, video downloading and conversion statuses.

Vidar makes use of redis for this functionality, you can enable this on your project by adding the following to your project settings:

TEMPLATES = [
    {
        ...
        "OPTIONS": {
            "context_processors": [
                ...
                'vidar.template_contexts.add_redis_messages',
                ...
            ],
        },
    },
]

and within one of your template files add the following:

{% include 'vidar/messages-redis.html' %}

Configurable Settings

Note: VIDAR_SETTING_GETTER and VIDAR_MEDIA_STORAGE_CLASS must be placed in your projects settings.py and will bypass the settings getter system.

VIDAR_AUTOMATED_DOWNLOADS_DAILY_LIMIT (default: 400)

VIDAR_AUTOMATED_DOWNLOADS_DURATION_LIMIT_SPLIT (default: 90 * 60): If a video duration (in seconds) is longer than this value, the VIDAR_AUTOMATED_DOWNLOADS_PER_TASK_LIMIT will be halved.
VIDAR_AUTOMATED_DOWNLOADS_PER_TASK_LIMIT (default: 4): Maximum number of videos permitted to download per run of automated_archiver.

VIDAR_AUTOMATED_QUALITY_UPGRADES_PER_TASK_LIMIT (default: 4)

VIDAR_AUTOMATED_CRONTAB_CATCHUP (default: True)

When trigger_crontab_scans runs should it try to automatically find channels and playlists that failed to run earlier?

VIDAR_CHANNEL_BANNER_RATE_LIMIT (default: 30)

How many seconds between channel thumbnail updates?

Once a month a task will run to update channel banners, thumbnails, ...etc

VIDAR_CHANNEL_DIRECTORY_SCHEMA (default: "{{ channel.system_safe_name }}")

When saving files, use this to name the directory for this channel.

VIDAR_CHANNEL_BLOCK_RESCAN_WINDOW_HOURS (default: 2)

If a channel is scanned and then the automated system tries to scan again within this window, the channel is skipped.

VIDAR_CONVERT_FILE_TO_AUDIO_FORMAT (default: "vidar.helpers.file_helpers.convert_to_audio_format")

Dot notation path to a function that accepts filepath which generates an audio file using the given filepath.

You should only generate the audio file stored in a local path and return the path.

VIDAR_CONVERT_FILE_TO_HTML_PLAYABLE_FORMAT (default: "vidar.helpers.file_helpers.convert_to_html_playable_format")

Dot notation path to a function that accepts filepath which converts the given filepath into a playable format for an HTML5 video player.

You should only generate the conversion file stored in a local path and return the path.

VIDAR_COOKIES (default: None)

String of cookies to supply to yt-dlp.

If supplied, VIDAR_COOKIES_FILE will be ignored.

VIDAR_COOKIES_ALWAYS_REQUIRED (default False)

VIDAR_COOKIES_APPLY_ON_RETRIES (default: False)

If a video fails to download, should retries apply cookie settings?

VIDAR_COOKIES_CHECKER (default: "vidar.services.video_services.should_use_cookies")

Dot notation pathway to a function that returns True or False if the given video should supply cookies to yt-dlp.

Supplying this setting ignores VIDAR_COOKIES_APPLY_ON_RETRIES. It is your responsibility to replicate that functionality.:

def cookie_checker(video):: ... return False

VIDAR_COOKIES_FILE (default: None)

String or pathlib.Path to the local cookie file to be read.

VIDAR_COOKIES_GETTER (default: "vidar.services.video_services.get_cookies")

Dot notation pathway to a function that returns a string containing the cookies you want to use for the given video.

Supplying this setting ignores VIDAR_COOKIES and VIDAR_COOKIES_FILE. It is your responsibility to replicate that functionality.:

def cookie_getter(video, attempt=0):: ... return "my cookies here"

VIDAR_COMMENTS_MAX_PARENTS (default: "all")

VIDAR_COMMENTS_MAX_REPLIES (default: 100)

VIDAR_COMMENTS_MAX_REPLIES_PER_THREAD (default: 10)

VIDAR_COMMENTS_SORTING (default: "top")

VIDAR_COMMENTS_TOTAL_MAX_COMMENTS (default: 100)

VIDAR_CRON_DEFAULT_SELECTION (default: "6-22/4 * * *|7-21/4 * * *")

Hourly based scans are not advised, use daily, weekly, monthly, bi-yearly, or year.

If you want to use hourly, these are the base selection to choose from WITHOUT the minutes. Minutes are calculated on the fly and should not be supplied here.

So instead of m h dom mon dow you need to supply h dom mon dow.

You can supply multiple values by pipe | separation.

The default supplied above would alternate even and odd hours. Some would be assigned to run at 6,8,10,12,14,16,18,20,22 and the others at 7,9,11,13,15,17,19,21

VIDAR_CRONTAB_CHECK_INTERVAL (default: 10)

vidar's version of cron is based on the cron set for vidar.tasks.trigger_crontab_scans.

If trigger_crontab_scans is set to check every 10 minutes, set this value to 10.

If trigger_crontab_scans is set to check every 5 minute, set this value to 5.

VIDAR_CRONTAB_CHECK_INTERVAL_MAX_IN_DAYS (default: 3)

If the system went down for a day, there is a utility named catchup. If you use catchup, how many days prior to right now do you want to check for channels and playlists that should have been scanned.

So for instance channel Y is set to scan once a month on the 14th but my server went down on the 13th and today is the 15th. When everything starts up, channel Y will still have been missed. You can then run a manual catchup from the 13th to now and every channel and playlist that should've been scanned, will be scanned.

VIDAR_DELETE_DOWNLOAD_CACHE (default: True)

When finished downloading, delete cached files?

Files are downloaded to MEDIA_CACHE and then copied or hardlinked to MEDIA_ROOT, delete the cache copy?

VIDAR_DEFAULT_QUALITY (default: 1080)

Used during the creation of channels and playlists as a default option. Also becomes the default on the manual video download form.

VIDAR_DISCORD_URL (default: None)

VIDAR_DOWNLOAD_SPEED_RATE_LIMIT (default: 5000)

See yt-dlp Download Option --limit-rate

VIDAR_ENSURE_FILE_IS_LOCAL (default: "vidar.helpers.file_helpers.ensure_file_is_local")

Dot notation path to a function that accepts file_field.

file_field is the FileField of the file being worked on. Be it video.file or similar.

This idea here is, if the system is configured with remote based storage and we need to work on the file for conversion purposes, this function will copy the file into a local location.

The function must return filepath, boolean where filepath is the local path and boolean indicates if the filepath returned is copied from a remote location.

VIDAR_GOTIFY_PRIORITY (default: 5)

Gotify message with priority >= 5

Android push notification For information I need to know instantly

Gotify message with priority < 5

I see notification on PC, if I happen to be on computer I see notification, if I manually open gotify on Android For "nice to know" information

VIDAR_GOTIFY_URL (default: None)

VIDAR_GOTIFY_URL_VERIFY (default: True)

VIDAR_LOAD_SPONSORBLOCK_DATA_ON_DOWNLOAD (default: True)

VIDAR_MEDIA_CACHE (default: "cache/"): Temporary directory to use when downloading videos before conversion and saving to MEDIA_ROOT.

VIDAR_MEDIA_HARDLINK (default: False)

VIDAR_MEDIA_ROOT (default: settings.MEDIA_ROOT)

VIDAR_MEDIA_URL (default: settings.MEDIA_URL)

VIDAR_MEDIA_STORAGE_CLASS (default: "vidar.storages.LocalFileSystemStorage")

Dot notation path to a class that's used as the base storage.

Note: VIDAR_MEDIA_STORAGE_CLASS does not use settings getter, it uses django.conf.settings directly. Place your configuration within your projects settings.py.

VIDAR_METADATA_ALBUM (default: "vidar.services.video_services.metadata_album")

Dot notation path to a function that accepts video and returns the album for navigator.mediaSession.metadata used on the video player.

VIDAR_METADATA_ARTIST (default: "vidar.services.video_services.metadata_artist")

Dot notation path to a function that accepts video and returns the artist for navigator.mediaSession.metadata used on the video player.

VIDAR_NOTIFICATIONS_PLAYLIST_ADDED_BY_MIRROR (default: True)

VIDAR_NOTIFICATIONS_PLAYLIST_DISABLED_DUE_TO_ERRORS (default: True)

VIDAR_NOTIFICATIONS_PLAYLIST_DISABLED_DUE_TO_STRING (default: True)

VIDAR_NOTIFICATIONS_VIDEO_ADDED_TO_PLAYLIST (default: True)

VIDAR_NOTIFICATIONS_VIDEO_READDED_TO_PLAYLIST (default: True)

VIDAR_NOTIFICATIONS_VIDEO_REMOVED_FROM_PLAYLIST (default: True)

VIDAR_PLAYLIST_BLOCK_RESCAN_WINDOW_HOURS (default: 2)

VIDAR_PRIVACY_STATUS_CHECK_HOURS_PER_DAY (default: 16)

How many hours per day does the update_video_statuses_and_details task run for?

VIDAR_PRIVACY_STATUS_CHECK_MAX_CHECK_PER_VIDEO (default: 3)

How many times should an update_video_details be used on a video, automatically.

VIDAR_PRIVACY_STATUS_CHECK_MIN_AGE (default: 30)

How many days before a video status should be checked.

VIDAR_PRIVACY_STATUS_CHECK_FORCE_CHECK_PER_CALL (default: 0)

How many videos to check per-call of the update_video_details task. The task by default calculates the number of videos to scan that day based on the number of pending videos divided by the range of check

VIDAR_PROXIES (default: [])

A selection of proxies to use:

VIDAR_PROXIES = ['proxy1', 'proxy2']
# or
VIDAR_PROXIES = "prox1,proxy2"
# or
VIDAR_PROXIES = "myproj.proxies.get_proxy"
# or
VIDAR_PROXIES = my_custom_vidar_get_proxy

Supplying a callable or a dot notation path to a function and it will be called with the previous proxies, the current video being attempted, and the number of attempt the system is on. The callable must return a string containing the connection string for a proxy to use, or return None to not use a proxy.:

def my_custom_vidar_get_proxy(previous_proxies=None, instance=None, attempt=None):
    ...

VIDAR_PROXIES = my_custom_vidar_get_proxy

VIDAR_PROXIES_DEFAULT (default: "")

If you use a proxy for yt-dlp, this is the base proxy value to supply in the event all other VIDAR_PROXIES fail

VIDAR_REDIS_ENABLED (default: True)

If False vidar will not send any messages to redis.

VIDAR_REDIS_URL (default: None)

URL to connect to redis, will use settings.CELERY_BROKER_URL if it exists

Note: VIDAR_REDIS_URL does not use settings getter, it uses django.conf.settings directly. Place your configuration within your projects settings.py.

VIDAR_REDIS_CHANNEL_INDEXING (default: True)

Update redis messaging when a Channel is being indexed

VIDAR_REDIS_PLAYLIST_INDEXING (default: True)

Update redis messaging when a Playlist is being indexed

VIDAR_REDIS_VIDEO_CONVERSION_FINISHED (default: True)

VIDAR_REDIS_VIDEO_CONVERSION_STARTED (default: True)

VIDAR_SAVE_INFO_JSON_FILE (default: True)

Write info.json file alongside video file?

VIDAR_SETTING_GETTER

By default all VIDAR_* settings are read from the primary django project's settings (django.conf.settings).

You can modify this by supplying your own function that returns the necessary information.

In your django primary settings file, supply a dotted string path to a function that accepts name and a default:

VIDAR_SETTING_GETTER = 'myproj.settings_getters.my_project_settings_getter'

myproj/settings_getters.py:

def my_project_settings_getter(name, default):
    # Get the setting that related to name and return its value
    return ...

Here is an example that pulls from django settings if it exists, otherwise it pulls from a model that stores settings

core_data/models.py:

class Setting(models.Model):

    name = models.CharField(max_length=255)
    value = models.TextField(blank=True)

    @classmethod
    def get_value(cls, name, default=None):
        setting, _ = cls.objects.get_or_create(name=name, defaults=dict(default=default))
        value = setting.value

        if value.lower() in ['true', 'false']:
            return value.lower() == 'true'

        if value.isdigit():
            return int(value)

        return value

core_data/settings_getters.py:

from django.conf import settings
from core_data.models import Setting


def get_vidar_setting(name, default):

    if hasattr(settings, name):
        return getattr(settings, name)

    return Setting.get_value(name=name, default=default)

Note: VIDAR_SETTING_GETTER does not use settings getter as that causes infinite loops, it uses django.conf.settings directly. Place your configuration within your projects settings.py.

VIDAR_SHOULD_CONVERT_FILE_TO_HTML_PLAYABLE_FORMAT (default: "vidar.helpers.file_helpers.should_convert_to_html_playable_format")

Dot notation path to a function that accepts filepath which returns boolean if the given filepath is considered a format that requires conversion into a playable format for an HTML5 video player.

VIDAR_SHORTS_FORCE_MAX_QUALITY (default: True)

When downloading shorts, grab max quality available?

VIDAR_SLOW_FULL_ARCHIVE_TASK_DOWNLOAD_LIMIT (default: 1)

How many videos to download per task run.

VIDAR_VIDEO_AUTO_DOWNLOAD_LIVE_AMQ_WHEN_DETECTED (default: True)

When update_video_details task is called, a video's live quality may have been updated since it was last downloaded. Maybe the download task grabbed 480p while youtube was still processing 1080p. If a channel is set to download the best quality available, this will track if a videos quality has been upgraded since the video was last downloaded. If so, redownload it at max quality.

VIDAR_VIDEO_DOWNLOAD_ERROR_ATTEMPTS (default: 70)

How many times to try downloading a video, divide this by VIDAR_VIDEO_DOWNLOAD_ERROR_DAILY_ATTEMPTS to see how many days it takes to fully error and stop trying. Default is 14 days worth.

VIDAR_VIDEO_DOWNLOAD_ERROR_DAILY_ATTEMPTS (default: 5)

VIDAR_VIDEO_DOWNLOAD_ERROR_WAIT_PERIOD (default: 60)

How many minutes to wait between error attempts

default: "{{ video.upload_date|date:"Y-m-d" }} - {{ video.system_safe_title }} [{{ video.provider_object_id }}]"

VIDAR_VIDEO_FILENAME_SCHEMA

default: "{{ video.upload_date|date:"Y-m-d" }} - {{ video.system_safe_title }} [{{ video.provider_object_id }}]"

VIDAR_VIDEO_LIVE_DOWNLOAD_RETRY_HOURS (default: 6)

How many hours to wait before checking if a Live (premiering) video can be downloaded.

VIDAR_YTDLP_INITIALIZER (default: None)

Lets you handle the creation of the yt_dlp.YoutubeDL instance.

Function must accept action and instance.

action is str and will be one of the following
- playlist_details
- video_download
- video_details
- channel_details
- channel_videos
- channel_playlists
instance could be an object of type Video, Channel, Playlist, or not given at all.

Be sure to assign a default as seen below.

def my_ytdlp_instance(action, instance=None, **kwargs):
    kwargs["proxy"] = "..."
    kwargs["cookiefile"] = "/home/user/cookies.txt"
    return yt_dlp.YoutubeDL(kwargs)

VIDAR_YOUTUBEDL_INITIALIZER = my_ytdlp_instance

# or put it in a file such as myproj/ytdlp.py and then

VIDAR_YOUTUBEDL_INITIALIZER = 'myproj.ytdlp.my_ytdlp_instance'

Video File and Directory Schemas

The Video file and directory structure can be controlled in various ways.

The default is the system value of VIDAR_VIDEO_DIRECTORY_SCHEMA and VIDAR_VIDEO_FILENAME_SCHEMA.

These values can be overridden on the follow objects in descending order of application:

Video object
- video - the video being worked on
Channel object (if assigned)
- video - the video being worked on
- channel - the channel being worked on
Playlist object (first playlist with a schema value, ordered by inserted id)
- video - the video being worked on
- playlist - the playlist being worked on
System default
- video - the video being worked on

The bolded sub-items represent the values available through python's string formatting style:

{{ video.title }}
{{ channel.name }}
{{ playlist.title }}

You can review vidar/models.py models to find all fields available to you.

Channel Directory Schemas

The directory structure can be controlled in various ways.

The default is the system value of VIDAR_CHANNEL_DIRECTORY_SCHEMA.

These values can be overridden on the follow objects in descending order of application:

Channel object
- channel - the channel being worked on
System default
- channel - the channel being worked on

The bolded sub-items represent the values available through python's string formatting style:

{{ channel.name }}

You can review vidar/models.py models to find all fields available to you.
