Have this work on video and audio files as well

Hello,
Image steganography is cool and all... what if this supported video and audio directly, as well?

Hi,
Maybe you know a technique or algorithm for audio and/or video files?
Apart from using the metadata fields from the files (not really interesting) I have no idea how to do this concretely.

Thanks much for your work. I used ffmpeg to extract frames from a short video clip and watermarked each frame using stegano. I can verify that the individual frames do have the watermark data.

But when I use ffmpeg to re-render a video using each of those watermarked frames, and then extract a random frame from the output video, the extracted frame does not have the embedded watermark anymore.

Would you happen to know why that might be happening? I do check the video codec, resolution, fps, video bitrate, audio codec and bitrate and use those parameters at the time of re-rending the output video using the individual watermarked frames. Any help would be much appreciated.
