used to work always. is it just me? its checked in settings, restarted several times-
since a couple of weeks downloads ok but doesnt crc check like before

 

SFV / CRC Failed / hash check failed
https://support.jdownloader.org/Kno...crc-failed-failed-sfv-crc-md5-sha1-hash-check

 

I assume that you have enabled the function in the settings? Does the CRC check only not work for certain services/websites? You should know that not all services provide a checksum. If a checksum exists, it will be displayed in the file properties. If services/websites don't provide a checksum, then JDownloader won't check anything either.

 

I too noticed it depends on file hoster,
if the files are fine, don't trouble yourself with it

 

Yes, it does. But it only shows the result of the check.
But I meant the checksum as such. This is shown in plain text in the file properties. If there is none, then the hoster/website is not providing a checksum and there is no check because JD has no reference.

 

thanks for your input. it is downloads from the sister site, with a rapidgator account.
i checked lots of file properties, nothing shown. i may be out of luck with my win7 home x86 download notebook... i believe thats the cause

Yep, this is the most accurate answer. I've used JDownloader for centuries and usually (.sfv, .md5 or similar aside) there's no CRC check. In fact when I see one I'm kind of surprised.
I don't use it for rapidgator files though.

 

no problems with JD2 running in Docker VMs

 

I keep using JD2 because it's the fucking tweaker paradise but it does have two big problems:
- It doesn't have a freaking buffer. This not only skyrockets disk usage but also CPU. It used to have many years ago
- You don't have control over other disk intensive operations. When I say control I mean something like: wait until downloads complete, or only X operations at once. Two of the biggest examples:

- Mega downloads decryption
- Youtube videos muxing (when you download video and audio separately and at the end JD2 joins them into one mp4/mkv using Ffmpeg)​

But even without these two cases, the CPU usage is indeed way higher than it should be. I've even started to use yt-dl that has like a fuckzillion options and it's hell to learn.

 

That works fine. But I'm talking about heavy operations triggered automatically when the download finishes, regardless of the ongoing downloads. Concretely, I want to have the resources on the downloads.

I mean that JD2 does that automatically the moment you choose a non-standard combination, so most of them.
But once both audio and video are downloaded; again, the process of muxing them into the final video is triggered automatically.
JD2 names them "video46456blabla".dashVideo and "video46456blabla".dashAudio temporarily.

understood, pity,
I'm running some NASes and VMs, so Docker being basically only way,
at 500Mbit DL I don't see any slowdowns - that said I mostly use Web GUI, not local app

 

Having problems with JD2 today. It doesn't recognize links and can't resume the already started downloads. Win10.
