I think this is very close to watermarking and data stenciling, I believe it's called, which is basically hiding data in files.
It's pretty easy to do. For example, a GIF has headers that let the image library know where the picture ends, so additional data at the end of the file will not bother standard compliant libraries.
So, you can append as much data to the end of the GIF as you like, upload it, nobody knows, and your data is at the end of the file.
For example, I tried this on Minds and other social media services. I made a zip file in which I put some random cat memes, uploaded it to Minds, and my friend downloaded it, unzipped the file and got the cat memes out.
The GIF was only 1 pixel in size.
So, it is not too hard to hide data in a video stream, by watermarking. You can create any kind of pattern in your video, but it might make it harder, because many services will transcode your data first.
YouTube, for example, will transcode your video to MP4 and AAC codec, so your data will likely get lost, as the transcoder only grabs the data it knows about.
thats not new
aye, but you have different codecs, and what i am saying is that you use the literal footage not something added they might trow away
Other sites use a library called PNGCRUSH, which performs a similar function, and reduces extraneous data before storing and serving the image.
like,t heres software with algorythingms that scans files for hiden files inside file formats
@Risotto I think that might be a bit much. They are right now horrible but I think they were worse before the, “party flip” or whatever they call it
like.. uploading static
No, that's not new. I am not saying it is. I am just answering the quesiton.
but then, depending on the pattern, you can watch the actual video
Right. That's not too hard to program.
they cant just toss away literal video data, thats whats actually being requested to be played
they proccess video data
and images
For example, QR codes just encode images. You could write a plugin that transforms each image on the fly and renders the "hidden" video.
In computer security this is very similar to what is known as a "side channel".
@Deleted User Yes, I know. But, it could be in the video frame itself. For example, QR codes encode URLs. You can create an arbitrary encoding for data that you then display in each frame.
Even just morse code. They then represent bits.
It might not be very compact, but creating such a "coded" video is doable.
You could even go so far that it only makes sense if the watchers have a particular private key.
It would look like static, unless you have the decryption key. It's not so different from the encoding that TV channels used.

Anyway. It's pretty wacky, but I am just going along with the thought experiment.
yea but all that encoded data
is going to be stored in a server
probably FOR EVER
Side channel?
matter of time till ai catches on into this shit
What you want to know?
Yes. Somebody brought up uploading an encoded video to YouTube that can be played, but is not viewable in its original form until decoded.
the best is just dont send em any info to them
I was just walking through how one could create such an encoded video.
@Undead Mockingbird what the fick does that mean?
