What do MP4 metadata tags such as "gssd" or "gsst" mean? -

-

After

I am removing metadata from mp4 files and have found some suggestions that I could not recognize:" gssd ", "GSST", "gstd" and "gspu" are some of them

I know the keys defined for the iTunes (in the AtomicParsley's website), but those .mp4 files will not appear in I have analyzed with a hex editor. Instead, I think that this is not to say-me-some keys are not too respected to their values: their type is text and they like "0", "300,953" or "B4A7D6381HH"

Also have been introduced with these tags before to see? What do they mean?

After the

and suggest that those meta tags are added by Google for tracking purposes.

I did a little bit of testing myself, I took a video that I had uploaded to VEMEO and checked the metadata using MediaInfo. This tag did not include any of the GSST , gstd , gssd , gshh section in general section or any other In.

Next I uploaded Vimeo videos downloaded on YouTube. I once again proceeded to download the video and checked the Meta tag. Found that meta tags were present 

  GSST:. 0 gstd: 156,990 gssd: B4A7DD6E1MM1359518628237025 gshh: r1---sn-p5qlsu7r.c.youtube.com   
 Using Chrome's Developer Tools & gt; Resource XHR indicates videoplayback such as  gshh  This page has a direct link and is being embedded in the file. I could not determine what others have a shop.  
 
  Minor Update   
 I came back today and use my YouTube editing capabilities to add a filter to my video. I downloaded the video and some values ​​have changed.  
  GSST: 0 GSTD: 156850 GSDD: BADC 235C1mm 135 9 9 9 9 599 51718 GSH: R1 --- SN-P5q7ynl7.c.youtube.com   
 The superuser question noted that some of these values ​​change. In this example, the same video, only  gstd  and  gssd  have been replaced with the edit by YouTube, I thought  gssd  hash Maybe, but I did not find any evidence to support this idea.  
 For the curious, this video I used to test.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
