YTP DSL

Java CI

A Domain Specific Language to generate videos based on video libraries and some math.

It is inspired by https://github.com/FAMILIAR-project/VideoGen2 and https://twitter.com/acherm video editing DSL.

This project has two main goals:

  • provide a cool playground for DSL and model oriented software and how to tackle technical stuff,
  • produce dumb content and crappy videos.

Main difference is that this project doesn't aim to produce regular video editing but to provide a fun way to generate random sequences at every run.

The language is there to construct a set of inputs to guide the stochastic decisions: total duration of the output clip, number of cuts, type of transition etc.

Backend video editing is based on ffmpeg and a java wrapper. For now all the magic happens in fr.ytpdsl.parent/fr.ytpdsl/

Features

A cool DSL, lame videos and bad algorithm for bad editing.

Grammar based DSL with no concrete internal structure yet, using a Java ffmpeg wrapper as a backend.

Grammar

The grammar is moving with the development of new features, some part are from the original project or here as draft of upcoming or test features.

Roadmap

  • standalone version, i.e java and maven only, no Eclipse RCP to build and use,
  • store metadata of linked media to a local db,
  • separate library media from media definiton from a path and a time code+duration,
  • allow custom filter to be written,
  • generic input connector for yt link or remote content,
  • text to speech to add audio track on existing audio&video or in place of audio
  • media analysis such as audio bpm, srt NLP

and so much more, from better input (besides DSL) to better output (direct uploading to host server).

Contributing

This is a toy project, nothing big but if you have feedbacks open an issue or ping on twitter or even by email (details on my website).

You can’t perform that action at this time.
