This is one of the simpler versions of the jav script which takes a video code as parameter and streams the video using mpv.  Many derivatives of the original jav shell function were made, but this one is mine.
https://warosu.org/jp/thread/32431725#p32464690

#!/bin/sh

jav_name() {
  if [ -z "$1" ]; then
    read name
  else
    name="$1"
  fi
  echo $name
}

jav_url () {
  name="$(jav_name $1)"
  links="(curl -s "$(curl -s "name/"">https://www2.javhdporn.net/video/$name/" | grep "embedURL" | grep -o "{.*}" | jq '.["@graph"]' | jq -r '.[].embedURL' | sed '/^null$/d' | sed 's/\/v\//\/api\/source\//')" --data-raw 'r=&d=javmvp.com' | jq -r '.data[] | select(.label | contains("720p", "480p","360p")).file' | tail -n1)"
  echo "$links"
}

mpv "$(jav_url $1)"

Example:

jav sspd-152

The code tag here is no bueno.  It actually corrupted the code by interpreting a $ as a cue to start turning text green, removing the $ in the process.  Let's see what happens if I poste a pastebin URL.

I made a userscript for use on endchan /cumg/ to embed pastebins directly on the page like 4chan does.  In the future, maybe we could embed more things beyond pastebin.

unfortunately not ideal because pastebin are fucking cucks. it is preferred to post the code directly on the coom.tech wiki and just link to that.

Please throw a post to the Endchan admins telling them about this issue.

It's really hard to format code well on the coom.tech wiki.  The SyntaxHighlight extension (which comes standard with MediaWiki) needs to be enabled at the very least.

https://www.mediawiki.org/wiki/Extension:SyntaxHighlight
>>/39/
Yeah, I've been doing it in quotes for now but obviously not ideal.
I have no way to contact the wiki host so it's a matter of trying to reach out to him.

I've posted on the discussion page about other stuff, but haven't seen a response yet.

Oh wait, it's really not working.  javhdporn.net changes things up to stop people from downloading.  This could take some time to figure out.
i will write a bash script to download from iwara.
i used iwara-dl from github before, but it's dead. wget should work fine, right?
>>/57/

wget should be fine.

i am stuck because the download link doesn't appear in the html page that is downloaded using curl/wget. it appears that the download link is generated with js in the browser and i don't know how to go around this. if you have some ideas - please respond
>>/57/
>>/59/
Why re-invent the wheel?
youtube-dl can parse and download from iwara.
If you want to use wget to download then you can use youtube-dl with --get-url flag and pass it to wget.
But if you want to make your own extractor, then you can look up at the extractor and make your own
https://github.com/ytdl-org/youtube-dl/blob/master/youtube_dl/extractor/iwara.py
I'm not sure since I know nothing about python, but it seems to get the video url from iwara API, using JSON.
I think you can parse JSON with jq package.
>>/60/
i remember it not working for me, but it works now, so whatever
thanks for pointing me in the right direction

What's a good instagram mirror and is there a userscript to redirect instagram profile links to that site?
Here's a Greasemonkey script I wrote that lets you search for a DL Site game on Nyaa in case you're an H game addict like me:

Using mitmproxy, 
https://mitmproxy.org/
I was able to find the index.m3u8 file, but I don't know how to figure out the URL for it programatically.
https://hls1.gslb.ru/hls/Cen/SSPD-150.mp4/index.m3u8

This m3u8 file contains a list of all the parts that can be downloaded and then concatenated together.
The pattern in this case looks like:
https://hls1.gslb.ru/hls/Cen/SSPD-150.mp4/cdn-1-v1-a1.ts
https://hls1.gslb.ru/hls/Cen/SSPD-150.mp4/cdn-2-v1-a1.ts
https://hls1.gslb.ru/hls/Cen/SSPD-150.mp4/cdn-3-v1-a1.ts
all the way to 554.

Alternatively, you can feed the m3u8 URL directly to mpv to stream the video.

mpv https://hls1.gslb.ru/hls/Cen/SSPD-150.mp4/index.m3u8

Download and Combine m3u8 Stream with ffmpeg

> I was able to find the index.m3u8 file, but I don't know how to figure out the URL for it programatically.
The devs at javhdporn.net have made it very difficult to inspect the underlying DOM and JS.  
They're using some kind of devtools detector, and 
it's not as easy to disable as it was in this other case:
https://coom.tech/index.php?title=Tricks#Download_Videos_From_Sites_That_Disable_Downloading

One heavy-handed approach to finding the index.m3u8 URL could be to use puppeteer to browse to the page and 
click around while setting up some code to monitor network requests.

Out of curiosity, I tried:
mpv ">https://hls1.gslb.ru/hls/Cen/ADN-219.mp4/index.m3u8
and it didn't work.
I don't have mitmproxy setup on the laptop I'm currently using, but 
I wonder what the right m3u8 URL is for ADN-219.
My guess is that the "Cen" part will be different, but everything else would follow the same structure.

Here's a thread in /bant/ that has a list of UserScripts for 4chan.
This doesn't include /cumg/ work, but it's nice to know what else exists.

> https://hls1.gslb.ru/hls/Cen/ADN-219.mp4/index.m3u8

I had a little bad luck.
I guessed the correct URL for ADN-219, but 
the Russian server didn't have the data, so 
it couldn't play it.
I tried ADN-115, and it worked.
We may have found a working pattern for the Russian servers.


mpv https://hls1.gslb.ru/hls/Cen/ADN-115.mp4/index.m3u8


Replace "ADN-115" with the code of the video you want, and
this will work for any video that's hosted on Russian servers.
However, many of their recent uploads are not on their Russian servers.
Similar patterns probably exist for their Dutch, French, and German servers, but
I'll leave that as an exercise for the reader.
If this gets automated,
it'll probably be abused again, because
c00mers don't know when to stop.

PS:  I think the "Cen" stands for censored.

It's not going to be that easy for newer uploads.
I tried to find the URLs for NATR-673 which was
uploaded on January 9, 2022, and 
it's available on DE, NL, and FR servers.
I tried the NL servers, and I found 4 files.
One master.m3u8 and 3 index*.m3u8 files for different resolutions.

Master https://www41.akamai-cdn-content.com/hls/tysxfic6ys6oj6cdadgbjw2ioqjuushxic4l2x7iz,jeyxolv7cdnjh2qtjdq,abyxolv7cdoj6lnrmuq,2ayvolv7cdls6dro2qa,.urlset/master.m3u8?client=88.208.39.96

The newer files don't follow the simple pattern that the older files do.

...tries to download the video parts as fast as possible which makes it hit the Russian server's rate limit often.
ffmpeg will still power through the errors and eventually finish the download, but
it would be nice to slow ffmpeg down to stay under their rate limit.
There doesn't seem to be an easy way to do that though.
