Where are the extractors located? - youtube-dl

I am trying to modify one to two extractors, but I can't seem to find them on my Mac and I cannot find any information as to where they are located.
Any help would be appreciated.

You can find all extractors in the youtube_dl/extractor subdirectory in the source code.
For more information on how to add extractors, consult the documentation.

VehicleObstacleShadowing configuration for Veins

How should I configure VehicleObstacleShadowing in the config.xml file in VEINS? I could not find an example so asking here for experts to shed light on it.
If you are referring to whether it reads any parameters from the analoguemodel configuration (e.g., config.xml), it does not need any. You can double-check by looking at the source code instantiating it.

Convert a VMS HELP file to HTML

VMS uses a Help file format for user and code documentation. I have created a Help file for a library. Is there a command to convert a VMS Help file to HTML?
The simple answer is: no.
Almost all OpenVMS HELP files are generated from common documentation
sources. The tool, which was used for that, was DECdocument. It can create printable documentation as well as PDF, HTML and HELP files. And you can select, which piece of information goes where. So the not so simple answer is, use such a tool to create both your HELP and HTML files. DECdocument was (is?) available as a product from Touch Technologies, Inc. Whether it is worth to buy it for "converting" some HELP files, I don't know. Whether the product includes all you need to do the same as the OpenVMS documentation group did, I don't know either. It is quite possible, that, to get the wanted output, you need some macros, or include files etc. which were used/written by the OpenVMS documentation group and therefore are not part of the product.
OpenVMS help documentation is located in the SYS$SYSHELP directory.
$ TYPE SYS$SYSHELP:[...]*those doc*.doc;/out=abcd.txt
$ mail/sub="help" abcd.txt
To: your_email_id#emailxyz.com
$
Now, you will get the email in the body of the email and you can convert it into HTML.

GML and JPEG2000 library

have you ever worked with JPEG2000 and/or GML?.
I'm reading documentation about GMLJP2 but I don't find any libraries that implement this. I mean, as far as I know it should be possible to have a GML file within a jp2 file (that is, a single file with both of the thigs).
Also, it's difficult to get a viewer that integrates GML and JPEG2000.
Any information regarding how to work with GML or JPEG200 is wellcome ;-)
Many thanks!
PD: I want to work with C or C++ but it doesn't matter the language yet
"Also, it's difficult to get a viewer that integrates GML and JPEG2000."
As I understand GML is just a block of metadata in XML inserted into JPEG2000 file. Any decent decoder should be able to extract it.
I wrote a JP2 metadata editor and included basic GML support.
You can download it here:

See the "gml.jp2" file for an example.
Hope it will be helpful.

File Signature Validation

I Have used a utility written by Mark Russinovich, it is used to validate the file signature.
Any one have ideas how this can be done, i know it is not a simple code, but just i need some hints, APIs, steps, A guide map, Just to go in the correct direction.
I read too much a bout the cryptAPIs, then I read too much about the certAPIs, but i cannot get any thing useful to simply link a given file with the (unknown to me) data stored in the windows.
if any can help me in this issue please help, thanks a lot.
