Friendly Web HTTP API video editor with pluggable file storages, video editing backends, and streaming capabilities.

• create a project¹
• list all projects
• retrieve project details
• delete project
• duplicate project
• edit video:
  • trim
  • rotate
  • scale
  • crop
• capture a thumbnails for timeline²
• capture a thumbnail for a preview at a certain position of the video, with optional crop and rotate params
• upload a custom image file for a preview thumbnail
• get thumbnails files
• get video file
• stream video

1: project it's a record in db with metadata about video, thumbnails, version, processing statuses, links to files and etc.
2: timeline is a display of a list of pictures in chronological order. Useful if you build a UI.

These services must be installed, configured and running:

• Python (>= 3.6)
• FFmpeg
• MongoDB
• RabbitMQ (celery backend)

After required services were installed and started, you can proceed with a video server installation.

NOTE: Use virtualenv and pip to install python modules.

# clone project
git clone https://github.com/superdesk/video-server.git

# install video server for development
# NOTE: your virtualenv must be activated
pip install -e video-server/[dev]

• rename .env-example to .env and fill out your S3 bucket information

Video server consists from two main parts: http api and celery workers.

For starting an http api dev server:

1. Set FLASK_ENV env variable to development:

export FLASK_ENV=development

2. Run python -m videoserver.app

For starting a celery workers:

1. Run celery -A videoserver.worker worker

NOTE: You can run tests only if project was installed for development!
There are several options how you can run tests:

1. Run tests directly from your virtualenv.
   Execute pytest from video server root.

pytest

if you want to get a coverage report into your terminal screen

pytest --cov-report term-missing --cov

2. Run tests using tox.
   It runs tests for each python version specified in .python-version file.
   tox-pyenv plugin is used, so python versions from .python-version must be installed in yours pyenv. Just execute tox from video server root.

Video server is a module, but not ready to use instance.
For ready to use installation, please refer to the README file at: https://github.com/superdesk/video-server-app

Once server is started you can access a swagger via http://0.0.0.0:5050/swagger/

curl -X GET http://0.0.0.0:5050/projects/

curl -X POST http://0.0.0.0:5050/projects/ \

curl -X GET http://0.0.0.0:5050/projects/5d7b841764c598157d53ef4a

where 5d7b841764c598157d53ef4a is project's _id.

curl -X DELETE http://0.0.0.0:5050/projects/5d7b841764c598157d53ef4a

where 5d7b841764c598157d53ef4a is project's _id.

curl -X POST http://0.0.0.0:5050/projects/5d7b841764c598157d53ef4a/duplicate

where 5d7b841764c598157d53ef4a is project's _id you want to make a duplicate of.

⚠️ It's not permitted to edit an original project (version 1), instead use a duplicated project.

curl -X PUT \
  http://0.0.0.0:5050/projects/5d7a35a04be797ba845e7871 \
  -d '{
	"trim": "2,5"
}'

where 2 and 5 are seconds.

curl -X PUT \
  http://0.0.0.0:5050/projects/5d7a35a04be797ba845e7871 \
  -d '{
	"rotate": 90
}'

where 90 is rotate degree.

curl -X PUT \
  http://0.0.0.0:5050/projects/5d7a35a04be797ba845e7871 \
  -d '{
	"scale": 480
}'

where 480 is width you want to scale video to.

curl -X PUT \
  http://0.0.0.0:5050/projects/5d7a35a04be797ba845e7871 \
  -d '{
	"crop": "0,0,180,320"
}'

where width and height are respectively width and height of capturing area, and x and y are coordinates of top-left point of capturing area. https://ffmpeg.org/ffmpeg-filters.html#crop

curl -X GET 'http://0.0.0.0:5050/projects/5d7b90ed64c598157d53ef5d/thumbnails?type=timeline&amount=5'

curl -X GET 'http://0.0.0.0:5050/projects/5d7b98f52fac91d2e1ad7512/thumbnails?type=preview&position=5'

You can also specify optional crop param if you want to crop a preview thumbnail, just add crop="0,0,180,320". Example:

curl -X GET \
  'http://0.0.0.0:5050/projects/5d7b98f52fac91d2e1ad7512/thumbnails?type=preview&position=5&crop={%0A%09%09%22height%22:%20180,%0A%09%09%22width%22:%20320,%0A%09%09%22x%22:%200,%0A%09%09%22y%22:%200%0A%09}'
