Installing CouchPotato on WD PR4100

Recently I bought a 4 bay NAS equipment to store movies and whatnot. Ater a few rounds of googling I found that the device has some features and apps that were added by the community such as Plex and CouchPotato available here.

Documentation is not the best out there, but I eventually discovered that the entware package is required for most of the enhancements that you may want to add to the thing, so install it first. Ok, onto the installation of the CouchPotato that would enable me download the movies I want according to my preferences. Uploaded the binary code and it says it did its thing, but the service never came up. Interesting.

Well, basic troubleshooting indicated that the service related to the CouchPotato was no up. Checked the default couchpotato port 5050 and there was nothing there. The PR4100 saves all new softwares that you add on to the first bay disk in a folder called “/shares/Volume_1/Nas_Prog”.  Great! Found the couchpotato folder and started looking around. There is a bunch of scripts in there. One in particular says “start.sh”. Tried to run it and BAM! the error appeared.

Python not found? What the hell? Let’s check where python is. I used the command “find” because there was no  “whereis” command in this thing.

Alright so there is a python 2.7 installed but the name is a bit different from what the script is calling. Ok then.. lets adjust the “start.sh” script to have the proper python name and location.

Changed the “PYTHON_DIR” and PYTHON variable to reflect the correct path and name of python.

Done.

Now the service should come up for you as it did for me!

 

Quarantine diary – Person Crazyness Calculator

It was saturday afternoon and I was bored! I had just upgraded the family notebook with a new SSD hard drive and a more memory. It makes a great difference and I recommend you to do it as well, if you have a slow Intel I3 notebook around. While I was setting it up the idea of a calculating one´s crazyness hit me. Here it is.

Extract frames from video using Python threads and OpenCV

In my research I wanted to process each frame of a given video individually and also know some details about it. Here is the code I created to achieve it. The code in python will extract all the frames of the video and store it in a folder given as parameter. Im using OpenCV to get the video details and extract the frames and threads to do it quickly.

Content-Based Identification Algorithms Combination Framework Against Audiovisual Piracy

Author: Torres,A.; Demanboro A.C.

Abstract

With the event of the Internet, video and image files are widely shared and consumed by users from all over the world. Recent studies point out that one out of two internet users have engaged in activities classified as illicit. Unauthorized copy, distribution or publishing of digital content without the proper rights holder consent is what is commonly called piracy. Those that profit from digital piracy ignore the intellectual property laws and copyrights from the owners, programmers, distributors and many others that live and depend on the economic value of these assets. Methods to identify these files have emerged to preserve intellectual and commercial rights such as content-based identification techniques also known as perceptual hashing. With said techniques a unique identifier is generated making possible to compare two images or videos and decide if they are equal, similar or different. This article has as objective to discuss the application of content-based identification technologies as a method to fight piracy, presenting a framework where perceptual hashing can be used to prevent publishing and/or distribution of video content. The methodology proposed is to combine four types of perceptual hash (ahash, dhash, phash, whash) to make it possible to identify illegal videos with more accuracy. The results are encouraging, considering the most common forms of attacks.

Infinite loop using wget

Im working in a project where I have to simulate traffic to certain website sites. The solution had to be simple and while python would be the obvious choice bash was right there with wget to be used with less lines and libs than python.

Choose your Ecosystem and love your choice

The phrase “Choose your love and Love your choice” was said in 2011 by Thomas S.Monson, it has to do with marriage and love and fidelity but it made much more sense to me this last days when I decided to move away from Iphone\iOS and go to Android. Then I paraphrased Thomas with the following: Choose your Ecosystem and love your choice.

Christmas Challenge 2019

Hi there

Some of you might remember the Christmas Challenge 2018 right? It is about to become a tradition!!

This time I had an encounter with a rather unusual Santa Claus and he sent me a curious message along with a set corrupted files that I can’t open. He said that I had to read carefully the message below to be able to crack it… ingenious Santa!

The message goes like this:

 

“I come with many colors, so beautiful and bright, I turn so many houses into a beautiful sight. What am I?”

 

The files Santa sent:

Have fun a excellent Christmas!
