The YouTube DASH audio might not be played by some audio players. If you have multiple files with such format, you can convert them using the following command on Windows.
FOR %i IN (*) DO C:\Users\Downloads\ffmpeg-20160725-fb91850-win64-static\ffmpeg-20160725-fb91850-win64-static\bin\ffmpeg -i "%i" -vn -acodec copy "new\%i"
Note that you need to download ffmpeg first from here: https://ffmpeg.org/. Remember where you save the ffmpeg file (the directory to it).
Then open the command line window and navigate to the folder with the files to convert. From there issue the above command. Note that the converted files will be saved into the folder “new”.
I am trying out the Goddy cloud server with the following specific:
20GB No more than $5.00 /month ($0.0074 /hour) 512MB memory 1 core processor 20GB SSD disk 1TB transfer
However, when I install the shiny package, I got the following error message
g++: internal compiler error: Killed (program cc1plus)
It turned out there was enough memory on the server. I was able to solve the problem by temporarily adding a larger swap file using the method discussed here: http://lacey.se/posts/compiling-dplyr-on-low-memory-vps/
To do it, use the following script
sudo fallocate -l 1G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile
Then, install the package using
CXXFLAGS="-g -O2 --param ggc-min-expand=0 --param ggc-min-heapsize=8192" sudo su - -c "R -e \"install.packages('shiny', repos='http://cran.rstudio.com/')\""
