• Moving files into sub folders based by average filesize

  5 February 2016, by darkshaed

  I need the help of you programming savants in creating a batch script or powershell script that will move and divide a group of files from one directory into 4 subdirectories based on an average total filesize. After the sort, the sub-directories should be roughly equal in terms of folder size.

  Why do I need this?

  I have 4 computers that I would like to utilize for encoding via FFMPEG and it would be helpful for a script to divide a folder into 4 parts (sub-directories) based on a total average size.

  So lets say there are an assortment of movie files with varying different file sizes totaling to 100 GB, the script would divy the movie files and move them into 4 sub folders; each folder having around 25 GB. Doing this will allow the 4 machines to encode the sum of the data equally and efficiently.

  After all that encoding I’ll have 2 files, XYZ.(original Extension) and XYZ.264, A script that could compare the 2 files and delete the larger file would be extremely helpful and cut down on manual inspection.

  Thank you, I hope this is possible.

• avformat/udp: specify the local address for some source filtered multicast joins

  21 September 2018, by Marton Balint

  avformat/udp: specify the local address for some source filtered multicast joins
  We already use localaddr for the multicast joins without source filters, so we
  
  should use them for source filters as well. This patch only fixes the
  
  IP_ADD_SOURCE_MEMBERSHIP and the IP_BLOCK_SOURCE case.
  Unless we do this, the kernel automatically selects an interface based on the
  
  source address, and that interface might be different from the one set in
  
  localaddr. For blocked sources this even casues EINVAL because we joined the
  
  multicast group on a different interface.
