Converting .mov to .m3u8 with ffmpeg
22 avril 2015, par Tim BakerI’m trying to convert a file to get it ready for adapative streaming. Have a .mov file I’d like to make .m3u8
Using ffmpeg, but I’ll admit I’m not completely familiar with the process.
ffmpeg -i intro.mov -c:v libx264 -b:a 32k -c:a aac -strict -f segment.ts -segment_list playlist.m3u8I’m getting the following error :
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

Knitr Plot Animation - disappearing output files ?
20 avril 2015, par tcsI downloaded the latest ffmpeg (exe version), unzipped the files, renamed the directory to ffmpeg, copied the directory into c :\Program Files. I appended my PATH variable to include c :\Program Files\ffmpeg\bin. Finally, I restarted Rstudio.
While attempting to run the following code chunk :
```{r perf_plot, fig.width=7, fig.height=6, fig.show='animate'}
library(corrplot)
corrplot(m, method = "circle")
m<-sequence_2_matrix(perf_list[[1]])
corrplot(m)
for (i in 2:length(perf_list)) {
m<-(m*(i-1)+sequence_2_matrix(perf_list[[i]]))/i
corrplot(m,method = "circle")
}I see within the output in in my RMarkdown window that the ffmpeg call seems to be successfully run, but while watching the directory where my code is located the png that is attempted to be created can often disappear, or not appear at all. Strangeness.
