• How to prevent my users from installing ffmpeg themselves

  7 février 2018, par keys king

  I would like to develop a program for converting video formats based on the ffmpeg command line on mac. I should use c ++ or python. But now there is a problem that bothers me. I do not want my users to have to install the ffmpeg command themselves , before I use my program, so what should I do ? My question may be naive, I’m just a sophomore in college and I would be very grateful if you could help me.

  I should check whether there is ffmpeg in the program, and then use the command line to install it ? I hope my program can bring ffmpeg, rather than to install

  Sorry, I did not say clearly. I hope my program can be the same as the normal mac program can be placed directly into the Application folder. And then you can open directly. I will use qt to draw the interface

• Recommendataions for robust and invisible video watermarking software / library [on hold]

  1er mars 2014, par id128

  I am doing a research project in search of a robust and invisible video watermarking software / library (preferably in C++). It needs to meet the following requirements :

  • Robust - that is the watermark needs to survive common transformations such as re-encoding, A/D / D/A conversion, luminance/color change, shift, and crop (both in size and length)'

  • Invisible - to the human eye

  The watermark does not need to carry too much data - maybe a 64-bit UUID - and can be temporal or spatial. But I will need the ability to determine the existence (or not) of the watermark with only a few seconds of the video

  Some research I have done so far :

  • JAWS research paper (http://pdf.aminer.org/000/316/002/the_viva_project_digital_watermarking_for_broadcast_monitoring.pdf) but cannot find any implementations on the web and the authors are not responding to emails. Plus, that research is over 10 years old and I am hoping for something more modern.

  • OpenPuff - does not satisfy the robustness requirement in that the resulting video does not survive transformations.

  • ffmpeg software - I have figured out how to overlay a visible watermark, but that does not satisfy the invisibility requirement.

  Any ideas / suggestions / pointers will be awesome. Thanks.
