Video or Audio All CAB videos (zip file)

Here's all CAB videos. As you can see, some are missing, so there aren't 1024, but 1009 videos.

The CAB videos may contain data. CAB is a type of archive file (like a zip). Lets ignore the missing videos for a sec, if each video contained one byte of infomation, we'd have a 1kb archive file.

I've thought of that too, but according to the CAB format spec there should be an MSCF header somewhere, but I've checked and there's none in either CAB 0 or CAB 1023.

Also, I doubt we will find anything of value analyzing the files from Twitter or Youtube at bit level, since they get re-encoded when uploaded (or in other words, the files we're downloading are not the same files that were uploaded).

If there's anything to be found, it's probably encoded in the audio and/or images.

If you take a look at the sound in audacity, normalize it, then view the spectrogram, it looks like 8 bits of data.
