Google searching has failed me.

I'm looking at the metadata of a video file, and there is a section that has this:

gsst : 0 
gstd : 16160 
gssd : B4A7DD621HH1355268768848137 
gshh : r1---sn-p5qlsu7l.c.youtube.com

What do gsst, gstd, gssd, and gshh stand for? This video was downloaded from youtube.

Thanks!

Thank you for that.

And what would be the difference between a video with the above metadata and one with this:

gsst : 0 
gstd : 16160 
gssd : B4A7DD621HH

Sorry, couldn't resist making meta jokes.

I Googled and couldn't really find any library info, my only relevant result so far is this: http://superuser.com/questions/503868/how-i-can-remove-all-google-data-from-youtube-video-downloads so I'm going to assume it's internal tags assigned by Google to youtube videos somehow. I'm actually a bit curious now myself.

That's the only relevant link I found myself. I wondered if it was an internal tag from Google, and thought that maybe sst, std, ssd, and ssh were more common metadata tags that google tweaked for use with youtube and simply added a "g" to separate them from the common tags, but searching for sst, std, ssd, and ssh brought nothing illuminating either.

Edit: and I was appreciative of the bump. This is the kind of thread that most people gloss over. Should have named it something like "more scarjo nudes leak."

Hahahaha

I'd bring it up with some cs-friends but I'm not in contact with anyone working for Google and most of them don't know anything about video encoding anyway.

At least now if anyone else gets curious about out Google overlords tracking us, they will immediately find this thread and wonder how they can get their hands on those scarjo nudes.

Found one more thing that might be relevant: http://en.m.wikipedia.org/wiki/ISO_base_media_file_format

The ISO base media file format supports streaming of media data over a network as well as local playback. A file that supports streaming includes information about the data units to stream (how to serve the elementary stream data in the file over streaming protocols). This information is placed in additional tracks of the file called "hint" tracks. Separate "hint" tracks for different protocols may be included within the same file. The media will play over all such protocols without making any additional copies or versions of the media data. Existing media can be easily made streamable for other specific protocols by the addition of appropriate hint tracks. The media data itself need not be reformatted in any way. The streams sent by the servers under the direction of the hint tracks, need contain no trace of file-specific information. When the presentation is played back locally (not streamed), the hint tracks may be ignored. Hint tracks may be created by an authoring tool, or may be added to an existing file (presentation) by a hinting tool.[1] In media authored for progressive download the moov atom, which contains the index of frames should precede the movie data mdat atom.[47]

So it could be internal reference data or maybe streaming information for youtube playback.

Based upon that theory, then, only a file that had been uploaded and processed by youtube would have these tags in their metadata?

That would be my assumption since I can't find any public library information and Google would presumably have their own encoder. Although it might show up in a file ripped from YouTube and converted to another format, depending on what information the converter would leave out.

What's interesting is that the second file is in the .mov format, whereas the first one is a .mp4 file.

A cursory google search seems to indicate that most extensions/program that rip youtube videos do not do so in .mov format, so I thought, at first, that the .mov file might actually be the original file, but with the g* tags included in the metadata, I'm not so sure.

Considering the tags are initially identical, I was thinking maybe the tagger or converter just truncated the data at that point, and I guess that kinda backs up my theory.

No, we're doing this in public and you have to watch.

Thanks again. We're trying to determine whether the first video we have is the original video taken by someone's phone or if it was uploaded to youtube, downloaded again, and then sent to us. Seems like the later is the most likely, given the presence of these seemingly proprietary Google tags.

Bump for the evening crowd.

I thought GAF has a pretty strict no meta policy?

How deep into discussing meta can we get before it's too meta and we risk a ban?

As deep as it takes to answer my questions in the OP. Any deeper and Evilore pounces from the shadows and *poof* the light of another GAFfer is extinguished.
