JDownloader does not touch the stream at all. It simply downloads the segments and ffmpeg merging them to one file. Such errors may occur if the segment has a transport error or was buggy from the beginning.

I've downloaded file without any issues.
I suggest you check your memory with memtest86 and smart data of your disk. Might be same cause as *wrong video duration* issue.

This happens to all videos I downloaded from this site. *wrong duration* issue is kinda sporadical.

I tried to grab all stream segments via another IDM and ffmpeg merging them, which turned out fine.

I will try to do a memtest86 and smart data, is here any particular area I should look into?

* SMART Data Self Test didn't find any issue.

It is likely the problem with FFmpeg

"ffmpeg version 2.8.11-0ubuntu0.16.04.1 Copyright (c) 2000-2017 the FFmpeg developers"
This is the original one I had installed from the Xenial Xerus.

"ffmpeg version N-61041-g52a2138 Copyright (c) 2000-2014 the FFmpeg developers"
This is built version JD2 installed at "jd2/tools/linux/ffmpeg/x64/", now everything works perfect.

I tried to assign FFmpeg binary path in "jd2/cfg/org.jdownloader.controlling.ffmpeg.FFmpegSetup.json" to a 3.4 built early on, but it didn't work out. Received "FFMPeg does not answer" error while downloading, and the process is hanging. Could you please share some thoughts? Is it possible to swap binary path in cfg at all?

Regards and happy holidays!
