Hi! Sorry for the delay... What is the version of TCBlobDownload you are using?

from tcblobdownload.

NasH5169 commented on June 30, 2024

Thibault,

No problem ! :)

I'm using the last stable available on Git.

Nash.

purepure commented on June 30, 2024

Get the same issue. Do you have any update?

from tcblobdownload.

thibaultcha commented on June 30, 2024

Hi,

No updates, as I have no time to maintain this project these days. All I can tell you is that this comes from -updateTransferRate (https://github.com/thibaultCha/TCBlobDownload/blob/master/TCBlobDownload/TCBlobDownload/TCBlobDownloader.m#L345)

If you really are desperate you can modify the code to drop this functionality (bad but works), or, the best would be a PR with a fix hem hem :)

I don't have time to look into it before at least 2 weeks...

Thank for your hard work. Your library is really good and helpful.
Btw, I try to comment out implementation of that function but it still crash at another place:

thibaultcha commented on June 30, 2024

@purepure Wow, never saw this one. What version of iOS are you running on? How big is the file you are trying to download? How did you initialise your download?

from tcblobdownload.

purepure commented on June 30, 2024

I am using the latest version 7.1 and xcode 5.1.1. The file is small, about 15mb.
My setup is that:

NSString *customPath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"test"];
TCBlobDownloader *downloader = [sharedManager startDownloadWithURL:videoUrl
                                                            customPath:customPath 
                                                           andDelegate:self];
[downloader start];

Just simple like that. I add download's delegate with a simple line of code NSLog() inside to monitor progress. The crash happened when the download finished

from tcblobdownload.

thibaultcha commented on June 30, 2024

Does it work with the TCBlobDownloadExample project? With the same file? You can try by directly running it and copy/paste the file URL in the input field.

from tcblobdownload.

purepure commented on June 30, 2024

oh, I try to use your sample and here is the result: 1 file can be downloaded with yours and one is not. The error is that:

Error Domain=com.thibaultcha.tcblobdownload Code=2 "HTTP error code 416 (requested range not satisfiable) " UserInfo=0x9a49bb0 {httpStatus=416, NSLocalizedDescription=HTTP error code 416 (requested range not satisfiable) }

This error happend when I try to download a video from youtube. The direct url of that video can be access by browser (downloadable)

Maybe I get some mistake when integrate your project, but I dont think so. Because I can download a single file from youtube in my project by your libs. It crash when finished download process as I said before. Hope this help

from tcblobdownload.

thibaultcha commented on June 30, 2024

A 416 would probably be related to this, which is also reported to happen on YouTube videos by @NasH5169.

Ok so let's clarify things, we have:

An occasional range exception in updateTransferRate
A 416 on some YouTube videos
A NSFileHandleOperationException in didReceivaData by the end of the download (for a YouTube file again?)

I never tried TCBlobDownload on YouTube actually, and I see a lot of people use it to download videos on it, as almost all these issues seem related to it (you're trying to download YouTube videos right?)

So I'll try to work on it when I'll have some time, but not before a few weeks, sorry :/ If you are willing to share which videos you want to download, that could help me reproduce the issues. Thanks.

from tcblobdownload.

purepure commented on June 30, 2024

No problem, your work is very good. I will wait for next cool release of this library.

Actually I am trying to download video from youtube and it's cool if I can use all of your lib's features.
You can try any video on youtube, it happened very often. Btw, this is my video:

Sorry for bother you.
