Slides not advancing? #10

Closed vfulco closed 6 years ago

vfulco commented 6 years ago

First made the mistake of using an pre-existing and cut down reveal.js presentation, then rebuilt a brand new one from stock ioslides template.

Have checked all spacing and notation against the repo examples and can't get slides to advance regardless of whether I use the .md or .rmd versions. TIA

Hmm...examples are not advancing slides either, "air_comments.Rmd". R version 3.4 on Ubuntu 18.04

vfulco commented 6 years ago

[Solution]

Super cool and easy fix--> these instructions are buried in the ari_narrate.R code.

"If

' making a video from an \code{\link[rmarkdown]{ioslides_presentation}}

' you should use \code{"iterative"}."

Better if it were put right on the main page. Will add PR.

I'm super-excited about this, but I am having this same issue of slides not advancing on Ubuntu 18.04 with R 3.6.3. 

ari_narrate(
  ari_example("ari_comments.Rmd"),
  ari_example("ari_intro.html"),
  voice = "Kendra"
)

I've tried setting the capture_method argument to both iterative and vectorized with no luck.

The text-to-speech part works, but the video just stays on the first slide the whole time.

Any ideas?
