  • FFmpeg/avconv rotate video with watermark adding using PHP-FFmpeg

    18 décembre 2015, par skrystos

    I’ve got problem with rotating video and adding watermark during the same request. My system can get video from mobile devices and has to reformat it for HTML5. so I’m making mp4,webm and ogv formats. Everything works fine, I’ve figured out how to get video rotation using Mediainfo. I have only one problem. When I want add watermark and rotation to video during the same request I’ve got only video with watermark (in proper resolution and format) but without rotation. I’ve read that it is possible to achieve using complex-filter. Has anyone expirience how to make it possible using PHP-ffmpeg ? It is very simple to use library, and works for me so it would be really cool if it will start to work.

  • 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.

  • ffmpeg overlay a watermark image on a video every 15 minutes ?

    21 janvier 2016, par Charles

    So I have a snippet from a bash script that overlays a transparent image watermark onto a video file, like this :

    /usr/bin/ffmpeg -i input.mp4 -i out.png -filter_complex "overlay=10:10" /outputfolder/output.mp4

    Works beautifully, and fast.

    What I really need though, is to have the watermark only show up at the start of the video, and then every 15 minutes through the video afterwards, for 30 seconds at a time.

    Is this possible without multiple passes ?

    Thanks in advance for all the help !
