• Install python's 'albumentations' in Kaggle's R kernel ?

  22 avril 2022, par dfrankow

  I can start an R kernel on Kaggle, run

  


  library(reticulate)
py_install('albumentations')


  


  Works for awhile, then finishes.

  


  However, importing it produces an error :

  


  reticulate::import('albumentations')


  


  


  Error in py_module_import(module, convert = convert) : ImportError : libopenh264.so.5 : cannot open shared object file : No such file or directory

  


  


  This looks like this stackoverflow question.

  


  The problem seems to be in ffmpeg, but I'm not sure what or how to install something to get that library.

  


  Below is ldd output of ffmpeg, showing the library is not found.

  


  conda_update doesn't help.

  


  system2("which",
        args=c('ffmpeg'),
        stdout=T, stderr=T)


  


  


  '/root/.local/share/r-miniconda/envs/r-reticulate/bin/ffmpeg'

  


  


  system2("ldd",
        args=c('/root/.local/share/r-miniconda/envs/r-reticulate/bin/ffmpeg'),
        stdout=T, stderr=T)

• FFmpeg.AutoGen example of how to split audio file

  7 mars 2018, par Sven

  I want to use the FFmpeg.AutoGen project from here : https://github.com/Ruslan-B/FFmpeg.AutoGen

  I’m not familiar with the ffmpeg API, so I wanted to get an example of how to split an audio file into little files, for example the audio file is about 2 hours long (can be mp3,ogg,wav,etc.) and I want to split it into several little files of x minutes. The splitting should be done on the main audio file with timestamps from and to, for example from = 00:25:00 (meaning 25 minutes), to = 00:31:12 (meaning 31 minutes, 12 seconds) and the output should be the section from the main audio file, the result is 00:06:12 (meaning 6 minutes, 12 seconds) long.

  How can this task be achieved with the project ? Also a C example can help me, I would try to convert it into the framework.

  Thanks for your responses.

• Localisation : fixed Persian translation of min/max message.

  28 janvier 2016, par EsiKhoob

  Localisation : fixed Persian translation of min/max message.
  Closes #1673.
  Hello, and thank you for this good plugin
  
  I find a bug in Farsi (Persian) localization exist in messages_fa.js
  
  The "min"&"max" methods messages in that file have bug. The Farsi "min"
  
  `s message has this meaning : “please enter value greater that 0
  
  words.”
  
  Phrase meaning "word" should be removed from Farsi message.
