You aren't doing anything wrong. It's just that the video has only 3 minutes available for those without registered accounts. You could try and make an account.


[Attachment 78053 - Click to enlarge]

Edit: Seems I was mistaken. The manifest contains all the valid fragments. For some reason the output is kinda trashy but you can fix it with mkvtoolnix, both the video and audio. You will get the full 1 hour and 8 minutes. However the audio is still out of sync.

[Ganteng]

Thanks for reply @552nHxWW6GkN1l916N3ayz8HQoi, yes iam already have account, but the video still same, when it decrypt just 6min video. File size is more than1gb+

[2nHxWW6GkN1l916N3ayz8HQoi]

when it decrypt just 6min video. File size is more than1gb+

Use this command to download the video and keep the audio/video separated.

N_m3u8DL-RE.exe https://cdnjkt4.transvision.co.id:1000/catchup/4028c685651d7bcc01651f0db0bf0097/prod/4028c6858e844bc2018e8964da573aac/manifest.mpd --key 3680de59582949ec9ba83a9ca0754997:9c755da9b7a14a85a6a69b0c7eec1880

You will have video/audio separated and decrypted successfully but presenting your weird problem. Then put each file separately into mkvtoolnix and remux them. You will get 2 new files, an mkv and mka. You can then open them and you will notice the video and audio have the same durations as shown by N_m3u8.

The sync issue still remains, however, and it can't be fixed with a simple shifting of N milliseconds (+/-). You could try shifting it by intervals. See when the audio is out of sync again, split that video, and fix it again. But that's a lot of work. Maybe someone else has a better idea.

[Ganteng]

Thank u so much, its work

it works, just only shifting -900ms in mkvtoolnik and it sync to end the video, thanks a lot for your help

Are you sure? I admit, that I don't understand Indonesian at all. But by looking at their lips even with -900 ms the sync issue is still there. It may be ok in the beginning but the more the video goes on, the more the difference between audio-video increases.

you're right haha, then for now ill sync manual until find the best way to sync

[2nHxWW6GkN1l916N3ayz8HQoi]

Out of curiosity, in the original video (from the source url) is the audio perfectly in sync with the video, no matter the video section? I can't test it since I can't make an account.

I have a few things I'd like to ask and learn at the same time. Please check your direct messages, I've sent you a message there.

yes i try stream with 720p, 486p, and 360p they all perfectly sync no delay audio
you can use this acc if you want test

pass : qwerty123

Yeah, you're right. I dunno what the issue is. Never encountered something like this. They either did it on purpose to stop you from downloading something good using their public manifest or N_m3u8 has some bugs (looking at https://github.com/nilaoda/N_m3u8DL-RE/issues/244 the same issue seems to be present).

Regardless, there must be a smarter way than manually fixing the sync issue every time the audio goes out of sync. However, I don't know it. Maybe you're lucky and someone else explains how.

You can look in the sample URLs to see what kind of links it supports. I've skipped the muxing part because N_m3u8 has some bugs with the manifests from this site. Some of them work instantly, some don't. Those that don't work can be fixed by remuxing using mkvtoolnix as previously explained. However you still have the audio sync issue ¯\_(ツ)_/¯. Can't do anything about it.

The livestream commands have to be edited according to your case. Either download past fragments and continue or start downloading all the fragments from the present. Read the n_m3u8 github page to see what parameters you have and adjust the command according to what you need.

Edit: I won't maintain this script since their site is bugged as hell when it comes to manifests. But I'll leave the script in case someone wants to improve it.
