Embedding videos in Jekyll

One of the main reasons I went with a markdown -> pandoc portfolio site instead of using jekyll: I couldn’t figure out how to embed “local” videos (video files inside my site, not from youtube or vimeo) in the jekyll sites.

Previously I was using the Jekyll Freelancer theme. With some modifications to allow for arrow key navigation.

However, any file that had a youtube video, I had to drop down to raw HTML. This was pretty painful. And since I was coercing the posts format to deal with “projects”, I had a crazy directory structure, something like “2015-01-01-project1.html”, which made editing lots of projects at once really annoying.

Thus, recently I switched to making my portfolio/project site in Markdown.
This was still kind of painful, but gave me a lot more control over the look.
I also enjoyed the minimalist structure of the final site, as compared to the glossy-yet-not-super-functional previous look when I built my site on top of the jekyll freelancer theme.

With my new webdev experience from bashing at grav for days on end, I was pretty easily able to modify this youtube embed script to do what I wanted.

I still find the post-first nature of jekyll annoying, yet it seems very reasonable to me now that I can just ignore that functionality entirely and build the rest of the site taking advantage of the templating engine and data / yaml features. After bashing at Grav, I’m also a lot more comfortable writing my own “page templates” for iterating through data files.

That is, I now understand how to leave the posts folder blank (ignore it entirely) and just write pages using my own Liquid templates.

Before, the Jekyll structure seemed overwhelming, at as always I’m only updating/creating a portfolio site when I’m applying to something. So I would always get frustrated and give up halfway through when creating/updating the portfolio site would take at least two entire days away from applications.

I also just tried and really enjoy the jekyll admin plugin, which allows me to upload files (via drag-and-drop) and provides a convenient browser-based GUI for creating pages.

The markdown file format I ended up settling down on started getting tedious and hard to organize as well. There was a lot of repetition that Liquid templating would solve. And a lot of “magic filenames” that were not human-readable, and annoying to keep consistent.

So it may be time to redo my portfolio site again.

Grav is more powerful, but even more “jargon heavy” / heavier of a web framework. You can do fancy things such as user authentication etc. in Grav. But dangnggg it is a heavy framework with a really complex file structure that appears like magical voodoo that is impossible to understad to newcomers…

For a sample of the craziness, see: https://github.com/nouyang/grav-plugin-milestones

Anyhow.

On to the actual video-embedding plugin. The key was figuring out how to access the Jekyll site variables from within the plugin file. Turns out you use the syntax Jekyll.configuration({})['url' (and use “||” to provide a default value).

Steps

1. https://jekyllrb.com/docs/quickstart/
2. Create a file, “my_site/_plugins
(create the _plugins folder if it doesn’t exist yet in your jekyll install)
3. Create a file called “video.rb” (or whatever you want) with the code at the bottom of this page
4. Put a video file in your site. Usually you can create an “assets” or “downloads” folder. For instance, I put a “spacetestSMALL_512kb.mp4” file into “my_site/assets” folder
Note: mp4 works consistently in all my browsers. ogv did not.
4. Use in your posts with following format:
{% Video spacetestSMALL_512kb.mp4 500 400 %}
