Does this also happen on different files on same host?
Either the file is broken server side or some issues with local firewall/av/hardware Check your memory with memtest86 and the smart data of your disks

I'm currently trying to track down the issue (or rather, I already found it), but I need some help with fully fixing it.
Basically, Ninjastream splits up their files into 50MB chunks (or less) and prepends a "fake" PNG-File to each chunk (for whatever reason, but it's always the same size and presumably the same data; EDIT: it is the same data). Right now, the JD plugin only downloads the first chunk (using a hardcoded name) and dumps it to disk as-is. I already modified my local source checkout to retrieve all the chunk filenames, but right now I'm stuck on the task of "download each chunk, remove the PNG data from the start of each, and concat them into a single file". Are there any existing plugins where I can look up how such a functionality is implemented? |

I can help with plugin changes. Are those different URLs or one and the file is PNG-DATA chunks?
In case it is one large file, then I would recommend to download the file and then post process it to remove the png chunks Best would be you contact me via support@jdownloader.org

I see that is a chunked "in-browser chunked download" (I'm lacking the correct word).
Seems like the plugin was able to "get around" this when it was created first but now they must have changed something - this might not be an easy fix. Ticket: -psp-

Quote:
For the chunk format, the only thing that has to be removed from each chunk file is the first 120 bytes (which due to the file magic I assume is a PNG file, but that's not really important). Everything after those 120 bytes (i.e. everything from offset 0x78 up to the end of the file) is real data that should end up unchanged in the output file. Regarding the post-processing, do you have any examples for that on hand? I'll happily send you an E-Mail (I assume that helps with keeping the bug report clean), in case you deem IRC more fit for communicating I'm also online there. |

I've answered via mail. I won't find time today for chat but next week.

I have just updated the repository with a fix for Ninjastream and a (rather scrappy) implementation for skipping bytes in segmented downloads (thanks to Jiaz for the hint!). The latter one should probably be double-checked by someone, but as far as I can tell Ninjastream downloads work again.

When you pause or disconnect, the download restarts from the beginning.
Can't this problem be fixed? |

@anet: I'm working on segment resume support, yes

Now I can download the whole file but when I go to watch the video I only see a first part while the rest is all on a black screen.

If you pause or crash, the download starts all over again. Can this problem be solved?
Thanks in advance EDIT: Ah sorry, I saw you already answered this Last edited by anet; 31.01.2021 at 09:58. |

Hi,
seems like ninjastream.to is possibly trying to block downloadmanager so it's unclear when/if we will fix this plugin. However, you can use this download method as a workaround in the meantime. I've created a ticket for this issue: -psp-
