Who here has a Youtube-DL compile for WinXP?

[nicolaasjan]

When tested if this Node version would work on Vista, I got this:

The procedure entry point EventSetInformation could not be located in the dynamic link library ADVAPI32.dll

6. What about QuickJS?

Edit: It will be supported.

10. What is the minimum required version of Node/Bun/QuickJS?

QuickJS: 2023-12-9

QuickJS version 2025-09-13 or later is strongly recommended for performance reasons

https://bellard.org/quickjs/binary_releases/?C=M;O=D

For my Vista SP2 32-bit laptop: 

https://bellard.org/quickjs/binary_releases/quickjs-win-i686-2025-09-13.zip

... and: 

qjs -h

QuickJS version 2025-09-13
usage: qjs [options] [file [args]]
-h  --help         list options
-e  --eval EXPR    evaluate EXPR
-i  --interactive  go to interactive mode
-m  --module       load as ES6 module (default=autodetect)
    --script       load as ES6 script (default=autodetect)
-I  --include file include an additional file
    --std          make 'std' and 'os' available to the loaded script
-T  --trace        trace memory allocation
-d  --dump         dump the memory usage stats
    --memory-limit n  limit the memory usage to 'n' bytes (SI suffixes allowed)
    --stack-size n    limit the stack size to 'n' bytes (SI suffixes allowed)
    --no-unhandled-rejection  ignore unhandled promise rejections
-s                    strip all the debug info
    --strip-source    strip the source code
-q  --quit         just instantiate the interpreter and quit

Though, this might still mean nothing, as I haven't gotten around to actually trying 

https://github.com/yt-dlp/yt-dlp/pull/14157

on this machine...

Most sadly, this is only part of the story  ; probing the v20.19.2 (32-bit) binary (a whooping 61.3 MiB in filesize) with DependencyWalker, I found a total of six (6) Vista-incompatible function calls: 

in advapi32.dll:

EventSetInformation

in kernel32.dll:

K32GetModuleBaseNameW
K32GetProcessMemoryInfo
ResolveLocaleName
TryAcquireSRWLockExclusive
TryAcquireSRWLockShared

The first one can also be a thing on a partially updated Win7 SP1 install (see this); thank you for already raising a Vista-support issue with Vladimir  ...

Test binary here

1. This one does launch OK under Vista SP2 32-bit  .

8 hours ago, nicolaasjan said:

Added to the config file:

--remote-components ejs:github
--js-runtimes node
--remote-components ejs:npm

2. Instead of the cmdline flag/config setting

"--remote-components ejs:github"

you could've built the PyInstaller binary with the EJS components bundled, as will upstream do  : 

https://github.com/coletdjnz/yt-dlp-wiki-dev/blob/ejs/EJS.md#step-2-install-ejs-challenge-solver-scripts

Quote

Official PyInstaller-bundled executable -> No additional action required. All the necessary JavaScript components will be bundled with these executables.

You can install them via PyPI prior to PyInst compilation: 

python -m pip install -U yt-dlp-ejs

and, hopefully, they'll be integrated into the produced executable, just like the rest of the default Python modules...

3. " --remote-components ejs:npm" applies ONLY to deno/bun, NOT to node used on Win7  : 

https://github.com/coletdjnz/yt-dlp-wiki-dev/blob/ejs/EJS.md#option-2-enable-ejs-script-downloads-from-npm

4. At the time the binary was compiled, quickjs support hadn't yet arrived, thus: 

yt-dlp_x86 --ies youtube -vF "yrcIdXBwVww" --remote-components ejs:github --js-runtimes quickjs =>

I'm seeing archive "libfdk-aac-v2.0.3-158-gd8e6b1a-x86.7z" intended for Win7SP1_x86; this one affords a DLL much larger (2.10 MiB) than the DLL extracted from archive "libfdk-aac-2.0.3-158-d8e6b1a-win32-xpmod-P4.7z" (1.33 MiB) 

Either libfdk-aac library should work fine on Vista. 

The Windows 7 version was compiled with GCC 15 but it looks like I neglected to strip the file so it is larger than it needs to be.

I will link a corrected file next time.  Thanks for bringing that to my attention.

You're right. I should have read the Wiki first. 

Here is an updated build with quickjs support and EJS bundled.

However, quickjs isn't that quick...

It took 28 minutes to figure out `yt-dlp -F URL` (in the meantime using a lot of memory and CPU).

... Indeed  ; I still keep an old (2018) version of MABS on an external disk, I used that to "strip" the DLL, 

$ cd ~
$ strip "libfdk-aac-2.dll"

and filesize was reduced from 2.11 MiB to 1.73 MiB (but still larger than the 1.34 MiB of the "xpmod-P4" variety  ) ...

Go here.

Now it took 9 seconds to calculate. 😀️

Here is a test binary of yt-dlp for Windows XP:
https://dl.dropboxusercontent.com/scl/fi/nltccona7wcnn3otd2ek2/yt-dlp_XP_test.7z?rlkey=8t2m3esh9hy671bkp1wg0xq6a

Install Quickjs in your PATH and add `--js-runtimes quickjs` to your config.

I had just completed my initial testing of your latest build  on this old and under-resourced Vista SP2 32-bit laptop and,  thankfully , I couldn't possibly reproduce your initial miserable qjs execution times  ; FTR, this machine has a (2007-era) Intel Core2Duo T5250@1.50GHz CPU and 3GiB of DDR2 RAM; I used my stopwatch to time below yt-dlp command: 

yt-dlp_x86 --ies youtube --js-runtimes quickjs -vF "yrcIdXBwVww"

and it actually took just 43s from when I clicked ENTER to full completion:

Those 43s include the time the PyInst binary took to extract its content inside the %TEMP% folder of my Windows User Account  ; and this was for the FIRST yt-dlp invocation, next ones took even less ; TL:DR: QuickJS is totally workable here, thanks a lot to you, to the yt-dlp devs and to a certain GitHub member (barracuda156) who actually "fought" to have QJS included as a supported external JS runtime!

Install Quickjs in your PATH and add `--js-runtimes quickjs` to your config.

So, does the latest QJS (32-bit) launch on WinXP SP3? FWIW, I don't like adding stuff to PATH unless I can't do otherwise; placing the qjs.exe (with its DLL dependency) adjacent to the yt-dlp_x86.exe binary was all it took here  ...

And a slight word of caution: Of the four external JS runtimes supported by yt-dlp, QJS is the least secure one ; it has no sandbox, needs to write to the host machine's TEMP dir and is subject to some exploits related to Temp files:

Both QuickJS and QuickJS-NG do not fully allow executing files from stdin, so yt-dlp will create temporary files for each EJS script execution. This can theoretically lead to time-of-check to time-of-use (TOCTOU) vulnerabilities.

Myself, I'd ONLY invoke it from the cmdline when I need to use YT, not permanently enable it via a config setting; call me paranoid  ...

Kind regards.
