• tests : make sure subtitles tests are run with a rawdiff

  26 avril 2015, par Clément Bœsch

  tests : make sure subtitles tests are run with a rawdiff
  This will test properly CRLF with make fate, make fate-subtitles and any
  
  make fate-sub-* test. Before this commit, the rawdiff was triggered only
  
  by make fate-subtitles.
  Also make sure fate-sub-* only match the tests relying on fmtstdout
  
  command, to at least avoid failing on MingW. See
  
  https://ffmpeg.org/pipermail/ffmpeg-devel/2015-April/172395.html

• Pipe breaks when piping gif to ffmpeg

  20 avril 2015, par forwardslash

  I’ve been trying to pipe gifs to ffmpeg to turn them into mp4s but I keep getting I/O errors from the pipe when I try.

  Something like

  cat nyan.gif | ffmpeg -f gif -i - -pix_fmt yuv420p -y nyan.mp4

  The important part being pipe:0: Input/output error

  I’ve tried this in bash and zsh on OSX and Ubuntu and I get the same error on all of them. I get the same error when trying to pipe with curl or httpie. When I just have file as input it works fine. Am I missing something necessary when piping to ffmpeg ?

• Knitr Plot Animation - disappearing output files ?

  20 avril 2015, par tcs

  I 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.

  Any ideas on what might be happening ? I’ve tried adding in other graphs, and I see this random behavior of the file folder appearing disappearing, sometimes the file is created, other times not.
