In which document does the esds box of mp4 file have a detailed description? Why is it not found in the ISO/ IEC 14496-12 document
It’s not found in 14496-12 because it’s documented in 14496-1

I have converted a m4v file type into a mp4 file type with https://cloudconvert.com. Currently in my Visual Studio Code set up I have assests/video/videoName.mp4. When I click on the mp4 file I get a message saying "The file is cannot be displayed in the editor because it is binary or uses unsupported text encoding". Any tips? I may be overlooking a small detail.
you need to download the MPEG-4 PREVIEW extension, and then it will open normally
I know we are currently still in preview for VSTS wiki but I am just wondering if embedding/uploading a gif is supported. I'm looking to give our docs a little bit of extra documentation beyond just the standard image and definition.
Yes, gif is supported for VSTS Wiki page.
If the gif file located locally, you just need to drag the .gif file in editor window. And the format will convert similar as below:
If the gif files located in network, you can use the formate:
More details, you can refer the markdown syntax for images.
I'm searching for syntax / extension to include Language, Version and Formats links via shortcut similar to the one at the bottom-right of Sphinx documentation page:
Is it an reStructuredText directive or Sphinx extension that generates these links holder?
It's neither. The image states, "Free documentation hosting provided by Read the Docs", which generates this from your reStructuredText files and Sphinx documentation project.
You can read the docs about Read the Docs for versions and localization for languages. RTD builds HTML, PDF, and epub formats by default, but you can turn off PDF and epub in the admin under Advanced Settings for your project.
We are working on a project to deal with OOXML format, specifically DOCX format. We downloaded PDFs from ISO site (http://standards.iso.org/ittf/PubliclyAvailableStandards/index.html) but found all images in the PDF are black. Some images have colored lines but none of them has text.
Is there anyone read the standard?
Where I can get a good document with good images.
Thanks
You can take a look at the ECMA-376 version of the standard at the following link. I would download the third edition set of the pdf's as they are the most recent to date.
I am extracting metadata from mp4 files and found some keys that I cannot identify: "gssd", "gsst", "gstd" and "gspu" are some of them.
I know of keys defined for iTunes (in AtomicParsley's website there is some info), but those won't appear in the .mp4 files I have analyzed with a hex editor. Instead I find these not-telling-me-anything keys. Their values are also not very representative: their type is text and they look like "0", "300953" or "B4A7D6381HH"
Has anyone dealt with these tags before? What do they mean?
This superuser question and this forum post suggest that those meta tags are added by Google for tracking purposes.
I did a little test of my own. I took a video I uploaded to vimeo and checked the metadata using MediaInfo. It did not contain any of the tags gsst, gstd, gssd, gshh in the general section or any other section.
Next I uploaded the downloaded Vimeo video to YouTube. I proceeded to download the video once again and checked the meta tags. Turns out the meta tags were present.
gsst : 0
gstd : 156990
gssd : B4A7DD6E1MM1359518628237025
gshh : r1---sn-p5qlsu7r.c.youtube.com
Using Chrome's Developer tools > Resources it looks like gshh points to the XHR videoplayback. It's the direct link in the page and seems to be embedded in the file. I couldn't determine what the others store.
Minor Update
I went back today and used Youtube's editing capabilities to add a filter to my video. I downloaded the video and some of the values changed.
gsst : 0
gstd : 156850
gssd : BADC235C1MM1359899059491718
gshh : r1---sn-p5q7ynl7.c.youtube.com
The superuser question noted that some of these values change. In this instance, same video with an edit performed via Youtube, only gstd and gssd changed. I thought gssd might be a hash, but I found no evidence to support this idea.
For the curious, this is the video I used for the test.
