Ask how to combine video files from IQ.

[evilragnarok]

I'm not sure about the instructions for use. Is mine correct? Because when I use this command, I get a file time of only 0 seconds. I want to know if I need to use it. Do you have anything else to order?

Command code used.

    mp4decrypt.exe --key %Keys1% "vid.mp4" "vid_dec.mp4"
    mp4decrypt.exe --key %Keys2% "aud.m4a" "aud_dec.mp4"

The files have no header, so decryption does not work. Must be merged with 'init' file.

I was curious how to retrieve the file, didn't want it to be loaded, but thanks for the loading.

[2nHxWW6GkN1l916N3ayz8HQoi]

You can download using python and n_m3u8dl-re. Make sure you have python installed (including pip) and n_m3u8dl-re installed (including mp4decrypt, ffmpeg). The reason you need python is because it is tedious to append manually 30 fragments for a 3 hour video worst case. You need Thailand IP for that video. Make sure you get the right keys for your wanted resolution because not only do they have separate keys for audio/video, but also for resolution. So for a video with 4 different resolutions, you would have at least 8 unique keys. But you just need the ones for your res.

The next steps are done on firefox but you should be able to use other browsers. Now select any unwanted res, wait for the video to switch completely because it notifies you ("You are watching in 360p", etc). This is done to force specific requests to happen since the site loads the default res m3u8 on their html page and it is a hassle to extract it.

Then refresh page, wait for it to load on your bad unwanted res. After it loads completely, pause the video. Inspect network requests, filter for the text: "/dash?" . You may wanna zoom in/out so you can see the quality button. Click on it so you can select the wanted res. Once you do that and the dash request appears, click on it and copy the json raw response.


[Attachment 85660 - Click to enlarge]

Then make an empty folder. Create the files (double check so they're the right extension)
1. main.py
2. input.txt (in this file drop the copied dash raw json response)

In main.py drop this script

python main.py

You'll get the download command

Then with the edited/unedited command run it in the same folder. Ignore any information n_m3u8dl-re is showing like bitrate/duration etc, since they're bogus values anyway. Make sure you select both tracks and hit enter. Your file will download on the current folder. Ignore any console timestamp warnings if any.

Please select what you want to download:

The py script may fail in the following cases
1. the m3u8 isn't represented by a json and instead
1a. it's a direct m3u8 url, usually in a "m3u8Url" field value. In this case just use N_m3u8dl-re with the direct URL
1b. it's plaintext m3u8 (something like #EXTM3U ... etc). In this case copy the text value, unescape it if necessary, and save it a local m3u8 file then use N_m3u8DL-RE on it.

2. something changed in the json response representation or there's an entirely different case
- in this case you can share the input.txt file but not before removing private sensitive information like your IP because it's stored in it (or use a proxy to hide it).

Kudos to @lzaa for warning about the missing init file.

1a. it's a direct m3u8 url, usually in a "m3u8Url" field value. In this case just use N_m3u8dl-re with the direct URL
1b. it's plaintext m3u8 (something like #EXTM3U ... etc). In this case copy the text value, unescape it if necessary, and save it a local m3u8 file then use N_m3u8DL-RE on it.

2. something changed in the json response representation or there's an entirely different case
- in this case you can share the input.txt file but not before removing private sensitive information like your IP because it's stored in it (or use a proxy to hide it).

Kudos to @lzaa for warning about the missing init file.

Thank you very much for the advice. Let go of frustration with the system.
