HTML5 Video Editor Integration Guide

Deployment

The editor server instance could be installed locally using docker.

To get the docker-compose configuration files please contact info@solveigmm.com

Host requirements

RAM at least 2GB, 2 CPU ( AVX instructions set is required by mongodb)

HDD 20 GB of free space (Docker images size is 10 GB)

GPU to with minimum OpenGL 2.0 GLSL 1.10 support (optional, for chromakey feature)

Install docker compose

To install Docker Compose for your host please use https://www.docker.com/

Minimal docker version required 20.10.21

Ubuntu 22.04:

    sudo su
    apt-get update
    apt-get upgrade
    apt-get install docker-compose

Windows:

Follow installation instruction from official package https://www.docker.com

The WSL 2 option should be set to provides better performance than the Hyper-V backend

MacOS:

Follow installation instruction from official package https://www.docker.com

For the MACOS host docker should be run with ordinary user (without su privileges)

Configuration notes

Replace MASTER_SERVER_IP variable in docker_build_solveig/master/.env by your server IP address on the network (localhost and 127.0.0.1 will not work)

For the server instance there should be ports exposed and accessible for MASTER_SERVER_IP. Please expose it before running the server:

9092 – kafka
27017- mongodb
80 – nginx front
3478(TCP and UDP) - coturn

The main docker configuration file:

docker_build_solveig/master/docker-compose.yml

To run the server:

docker-compose up -d --force-recreate

To stop the server:

docker-compose down

The Editor is available by URL ( Google Chrome browser is recommended):

http://localhost

The test media files are located at ./smm_cloud_editor_v2/shared/files

You can try to put your own there to see it in media tab or import media files via browser

Chromakey requirements

For "chromakey" feature the host instance should have GPU with minimum OpenGL 2.0 GLSL 1.10 support.

The gpu driver should be installed and configured properly.

Amazon instances with gpu: https://docs.aws.amazon.com/dlami/latest/devguide/gpu.html

G4ad instance GPU driver installation

To install driver at G4ad instance:

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-amd-driver.html

Alternative way to install drivers:


Works with the kernel version linux-image-5.19.0-1029-aws
sudo apt update
sudo apt install linux-image-5.19.0-1029-aws linux-headers-5.19.0-1029-aws linux-modules-extra-5.19.0-1029
Change /etc/default/grub
GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux 5.19.0-1029-aws"
sudo update-grub
apt-mark hold 5.19.0-1029-aws
sudo reboot

uname -r (should display 5.19.0-1029-aws)

Remove the Newer Kernels:

sudo apt remove linux-image-6.8.0-1015-aws linux-headers-6.8.0-1015-aws
sudo apt remove linux-image-6.8.0-1018-aws linux-headers-6.8.0-1018-aws
sudo reboot

apt-get update
amdgpu-install --usecase=graphics --no-32
sudo reboot

External image library sources requirements

Pexels and Unsplash images source types requires developer's account creation:

https://www.pexels.com/api/documentation/#authorization

https://unsplash.com/developers

The Api keys are configured at "docker_build_solveig/master/.env" :

#PEXELS_API_KEY=<your_api_key>

#UNSPLASH_API_KEY=<your_api_key>

#UNSPLASH_API_SECRETE=<your_api_key_secrete>

#UNSPLASH_APP_NAME=<your_unsplash_app_name>

Customization

By default each user has options for customization since it has linked developer's profile (configured via ENABLE_DEV_PROFILE_FOR_USERS=TRUE environment variable).

You can adjust basic styles and text definitions via "Customize editor" UI.

With the developer's profile you can configure:

User interface styles and text definitions:
- companyName - Used at preview screen instead of default "Solveig Multimedia"
- appTitle - Used at page's header and "title" tag instead of default "Online Video Editor"
- svgLogo - Logo image used at preview screen and header
- customCSS - custom CSS that allows to change html elements styles
- customJS - custom JS that allows to run external scripts.
- customLanguage - custom JSON with text definitions.
See dev_profile_object for details.
callBackUrl to receive events that are performed by the user while using the editor. See CallBack events for details
Custom urls that will be used by the editor to fetch media assets information. See Override media assets information API and Generate media info for details
outputS3Bucket to upload output results to Amazon S3 Bucket. See S3 bucket configuration for details

If the server configured with disabled customization for regular users (ENABLE_DEV_PROFILE_FOR_USERS=FALSE) to configure UI it is required to create a developer's user profile to get an apiKey using /api/developer_profiles.

The customization UI will be available at https://smarteditingonline.solveigmm.com/?auth_token=<apiKey>

To create regular users sessions with customized interface use /api/users. The apiKey field should identify the developer's profile. The user's session will be available at https://smarteditingonline.solveigmm.com/?auth_token=<userId>

Override media assets information API

The Developer profile allows to override media assets information API by custom implementation at your server. The following variables available:

fetchFileUrl - to override fetching media information /api/mediafiles/<id>
mediaTabContentUrl to override fetch media files to display at media tab /api/mediafiles
fetchThumbnailUrl to override fetch media file's thumbnail to display at timeline/api/clip_thumbnails

The urls responses should include the headers to prevent CORS policy issues:

'Access-Control-Allow-Origin':'*'
'Access-Control-Allow-Headers':'content-type'

All request from the editor will contain an Authorization header with the token that was assigned to user's session at apiAuthToken

"Authorization": <auth_token>

Generate media info

The media file information required for Custom media assets could be prepared in advance.

Use existing html5editor backend server to generate media info.

All request should contain an Authorization header:

"Authorization": <valid_api_key>

valid_api_key - the valid api developer's key

Create media info task

Request:

POST
/api/task/mediainfo

Request Body:

{
  "originalUrl": <string>, (optional)
  "awsBucket": {           (optional)
    "awsBucketName":<string>,
    "awsAccessKey":<string>,
    "awsSecreteKey":<string>
  }
}

Description:

originalUrl - file's url of the orignal media file

awsBucket - AWS bucket credentials object. (Note: aws bucket processing works only with ENABLE_KEEP_MEDIAINFO_DATA=true)

Response:

{
  "id": <taskId>
}

Get media info

Request:

GET
/api/task/mediainfo/<taksId>

Response:

Status 202 - The media file processing is in progress

Status 200 - The media file was processed

JSON mediainfo object:

{
  "info":{
    "name":<string>,
    "filetype":<string>,
    "mediaType":<string>,
    "duration":<number>,
    "size":<number>,
    "width":<number>,
    "height":<number>,
    "thumbnail":<base64_encoded_png_image>,
    "previewUrl":<string_url>,
    "audioTracks":[<string>, <string>]
    },
  "thumbnails":[{
    "time":<number>,
    "data":<base64_encoded_png_image>
  }]
}

Description:

info - should be used as a response for custom api urls implementation ( fetchFileUrl, mediaTabContentUrl at devProfile ).

thumbnails - should be used to implement custom api url for timeline thumbnails (fetchThumbnailUrl at devProfile )

React video editor component example

Download source code

Online demo

In this example the video editor component "SolveigEditor" is embedded into React application.

The media url is imported using "videoUrl" property.

The callback "onVideoAdded" is called after the video was put into timeline.

The callback "onRenderComplete" is called after the project rendering completed with the url of the output media.

The "apiUrl" property defines the address of the backend api

To run example use:

npm install
npm start

index.js

/* eslint-disable no-unused-expressions */
/* eslint-disable no-sequences */
import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

Custom media assets with prepared media info

The media asset's information will be stored at locally installed editor's database. The media asset's file will be downloaded to fetch media info and removed after operation completed.

The user's session will be created with the custom media assets.

Download source code

Configure .env docker variables:

MASTER_SERVER_IP - the editor's ip address

ADMIN_SECRETE - secrete to manage developer profiles.

Register developer profile

Use ADMIN_SECRETE as Authorization header

Replace MASTER_SERVER_IP to actual value

{
  "fetchFileUrl": "http://MASTER_SERVER_IP/api/mediafiles",
  "mediaTabContentUrl": "http://MASTER_SERVER_IP/api/mediafiles",
  "fetchThumbnailUrl":"http://MASTER_SERVER_IP/api/clip_thumbnail"
}

The result is DEV_API_KEY created.

Create media info task

Using DEV_API_KEY as Authorization header create media info task request /api/task/mediainfo and wait for import process completed.

Specify originalUrl to media file:

originalUrl: <string>

or aws bucket credentials as follow:

awsBucket: {
         "awsBucketName":<string>
         "awsAccessKey":<string>,
         "awsSecreteKey":<string>,
}

Register user's session

{
  "apiKey": DEV_API_KEY,
  "apiAuthToken": DEV_API_KEY
}

The result is USER_SESSION_ID created.

Open user's session

Open the user's session via url

http://MASTER_SERVER_IP?session_id=USER_SESSION_ID

Example mediaFiles.json:

In this example the 'media_json_video_mxf_xavc.mxf' will be available to all user the 'media_json_url.mxf' will be visible only to single user (1701244924069)

{
  "entries":[
    {
      "originalPath": "media_json_video_mxf_xavc.mxf",
      "proxyPath": "media_json_video_mxf_xavc.mp4"
    },
    {
      "originalUrl": "https://smarteditingonline.solveigmm.com/files/media_json_url.mxf",
      "proxyUrl": "https://smarteditingonline.solveigmm.com/files/media_json_url.mp4",
      "userId": "1701244924069"
    }
  ]
}

Fields Description:

originalPath - The absolute or relative path to original media file

proxyPath - The absolute or relative path to proxy media file (used for preview media files with format natively not supported by browser)

HTML5 Video Editor - Backend Server API

Authorization

auth_token is used to identify user in API requests,

Backend uses WebSocket connection associated with auth_token in order to track if the user is online.

For the new connection auth_token is created as follow (JS):

const client = new WebSocket('ws://backendHost:backendPort/websocket')
  client.onopen = () => {
    const authToken = Date.now().toString()
    client.send(JSON.stringify({
      type: 'user_event',
      payload: { authToken },
    }))
  }
  client.onmessage = message => {
    const dataFromServer = JSON.parse(message.data)
    if (dataFromServer.type === 'ping') {
      client.send(JSON.stringify({
        type: 'pong',
      }))
    }
  }
