Generate videos out of animated HTML pages ========================================== This little project does only one simple thing: it generates a series of videos based on some data in `.yaml` files and a `template.html`, rendering each as MP4 files (using ffmpeg) from the moment an element `.capture` is displayed, until it is hidden. My primary goal was to create dynamic videos to introduce speakers in the video recording of the sessions at Golang Montréal meetups (https://golangmontreal.org). I wanted to cut the post-production cost of doing videos recordings of the session, so I coded the repetitive stuff. Check `talks.yaml`, `sponsors.yaml` and `event.yaml` to see the format. This mostly refers to the structure we use in https://github.com/gomtl/golangmontreal.org `content` and `data` dirs. See the included `template.html` for an example template. It then uses ChromeDriver (using [the agouti WebDriver implementation](https://github.com/sclevine/agouti) ) to open the browser, resize it properly, load the template from its own internal web server. It waits until an HTML node with a `capture` class appears (on the body for example). It then starts `ffmpeg` to capture the screen at 25 fps, writing an .mp4 file in H.264 to disk for each entry in the `data.yaml`. When the `capture` class disappears, the video stops. It then proceeds to the next video. Pretty simple eh ? Dependencies ------------ You need to have the binary for `ffmpeg` available in your PATH (with libx264 support). You also need [chromedriver](https://sites.google.com/a/chromium.org/chromedriver/downloads) to be in your PATH for agouti to pick up. You'll also need Google Chrome install.. I'll let you figure that one out. Limitations ----------- This currently runs only on Linux (uses the x11grab ffmpeg module). The window-decorations dimensions are modeled around the Ubuntu Unity environment and are currently hard-coded. It could be adapted to run on Windows though.
