In anticipation of new content, which should hopefully appear over the next week or so I have made some updates to my website. Most of these changes aren't public-facing. However, an entirely new section of the website is under construction and will hopefully be released by the end of the week. The only change you …

Intelligible blog title? Maybe, maybe not. The Advanced Encryption Standard (AES) has been widely recognised as government- and military-grade encryption for the past 12 years. The AES specification was initially established in 2001 by the U.S National Institute of Standards and Technology (NIST) to replace the then …

It would appear that the interference isn't caused by a lacking fdk-aac or any other similar library. It looks like I will have to try and filter/resample the audio frame or do something similar. Not sure exactly how I should go about this, so watch this space...

Since my last post couple of posts, I have been working on a few things at the same time. GTK+ (not a priority) As a GUI is not high on the list of requirements, I have decided to strip this out for simplicity. The UI I had built thus far was simplistic but also didn't look right on OS X. Cross Platform This is one of …

Now that I have a transcoding system, I have started looking into how to manipulate the motion vectors of certain frames - at the moment, this hasn't yielded any progress. Whilst researching this, I am looking into developing an AES cryptosystem for encrypting the embedded data. I have also started trying to get my …

Google doesn’t provide much information on transcoding video in C with FFmpeg – there are no examples anywhere of how to specifically do this. However, with a significant amount of determination and perseverance, I have successfully produced a system capable of transcoding a video file. It might have taken a day and a …

GTK+ is proving to be a very good GUI API for C – this really goes without saying given how GIMP, gedit, WMWare and various other applications have been built with it. I have nearly reached the point where all previously implemented functionality is accessible via the GUI. In fact, if everything goes to plan, I intend …

Transcoding one video container to another (with an audio and video stream) is proving more complex than initially expected. Whilst progress with transcoding has plateaued with no success, I have started to build a simple GUI to house current and future functionality. The GUI is being built using GTK+. Integrating GTK+ …

I have made good progress on the literature survey over the past week, writing a total of about ~3,300 words, giving what should be a detailed explanation of steganography and its counterpart, steganalysis. I currently reference 41 different papers, books, journals etc., and there are still about ten more sources that …

Following my meeting with Mike, we have successfully resolved the makefile compiling errors (full credit to Mike). I have also now written just short of 2,000 words towards my literature survey. I am hoping to have the first draft (complete with diagrams) finished before the end of tomorrow.
