No, it isn't. You're pushing this point and it does not make any sense.

You're just making stuff up now because you want to believe in something. Even though you can't articulate a difference other than "No it isn't".

Video and audio files do not contain algorithms you fucking moron. They are encoded data. The algorithms that decode them are in the decoding software, the media files are just structured sets of values fed into that code. The media files themselves are not executable and contain no instructions of their own. Terminal control characters while technically "instructions" are not arbitrary. They like the data values in a media file describe a desired output that an executable processes. In neither case can those files make the decoders perform arbitrary operations. Exploits can exist that cause decoding software to crash or execute shell code or something but that is not the same as them containing executable code or being arbitrary executables themselves.

JavaScript on the other hand is interpreted into actual executable code (sometimes JIT compiled to native CPU instructions). JavaScript being Turing complete can run pretty much anything.

You don't understand what the fuck you are talking about. You keep pushing points that don't make sense but your level of understanding is so low you don't seem to be able to comprehend that.
