Problems accessing codecs with ggplot and gganimate
19 décembre 2016, par noLongerRandomUsing gganimate. Can’t figure out how to properly access functionality of ffmpeg, specifically I want to change the codec I’m using in the video file I’m outputting.
# load packages
library(ggplot)
library(animation)
library(gganimate)
# Here's my data.frame
myDf <- data.frame(
year = c(1962, 1963, 1964, 1965, 1966, 1967, 1968, 1969, 1970, 1971, 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014),

)
#Basic plot
p <- ggplot(myDf, aes(x = year, y = bottom50, frame = year)) +
geom_line(color = "dodgerblue") +
geom_line(aes(y = top1), color = "darkred")The non-animated version gets me what I want :
And I get an animation version output to video with :
gganimate(p, interval = .1, title_frame = FALSE, "income.mp4")
That’s fine, but I want to change some the output parameters, specifically : alter the dimensions, the frame rate, and use a different codec.
# change some of the options
ani.options(ani.height = 1080, ani.width = 1920,
interval = 0.04166667, other.opts = "-vcodec qtrle -f mov")
# re-animate
gganimate(p, title_frame = FALSE, "income.mov")That gives me the following error :
Error in animation_saver(saver, filename) :
Don't know how to save animation of type movI’m using ’.mov’ as my file extension because I’m trying to change to the Animation codec (so it’s no longer a .mp4 wrapper). I’ve got ffmpeg installed, so this is probably a syntax issue. But the documentation isn’t very clear here ; gganimate doesn’t have any documentation on changing codecs (or outputting any video besides an mp4), and the animation package is light on specifics as well.

Also temporary enable the test so we get updated fate failure statistics

and ml archives indicate it failed on x86 openbsd with some compilers as wellReviewed-by : Derek Buitenhuis <derek.buitenhuis@gmail.com>
