  • Is it Possible To hide an information in a Image and convert it to video and decrypt it back with FFMPEG

    16 février 2014, par Ivan

    I am doing my project with the help of ffmpeg. I initially convert a video file in to images and hide some information in one of the images and convert it back to video. and in the receiver side the user should again convert the video containing the encrypted message in to images and get back the information from the image in which we have previously hided the information.

    I have done all these but after convert the encrypted image into video and then i convert back to image i am not able to get the hidden information from the converted image...How do i do this. Is there any way to hide infor mation in a image other than this...

  • FFmpeg removed video rotation information

    15 janvier 2016, par Mei Yi

    Currently I’m using FFmpeg to edit and compress video. But when I edit the video, it removed my metadata which is the video rotational information.

        String cmd = "-ss" +"command" + " ";

    The video is not rotated but the rotation information is removed and causes the video output to be changed.

    How do I maintain the video rotation information and also the video rotation ?

    Initially the matrix was Rotate 90 but the converted video is :

    Matrix{u=0.0, v=0.0, w=1.0, a=0.0, b=1.0, c=-1.0, d=0.0, tx=360.0, ty=0.0}

    The video conversion changed the rotation Matrix.

    Thank you.

    cbs : Ensure that reference fields always follow the associated pointer

    Having these together allows us to find both pointers given the address
    
of only one of them.
