How to cancel ongoing download

Can you guide me on how to cancel an ongoing download? Calling download again while another is downloading causes a crash. Thanks~

how can I access downloaded videos using a button in app ?

Downloading video is stuck on "Extracting...", when not connected to debugger

The app works great when the debugger is connected. However, when I tried running it (simulator or device), when not connected to the debugger, the download process gets stuck on the first step and obviously makes it extra challenging to debug, since it only glitches when the debugger is not connected

get stream URL

Is there a way i can get the steam URL without the downloading?

Requirements for the code to run elsewhere? (files, packages, libraries, etc.)

Hi,

I want to download a Youtube video (given the video id), save it in the app internally, and play/access it. I tried copying the files over and adding the package dependencies (e.g. ffmpeg, python, YoutubeDL), but when I ran the app and tried downloading a video, I get this error:

What else do I need to do for the DownloadViewController class to work?

App crashes when installed from Testflight

When testing on a device or simulator it works great but when installed from Testflight it crashes. Any idea why that could be?

HookMain crash when using `extractInfo`

Example project works without any issues and all unit tests working as expected too. However when I run the following code in a fresh project I get crash.

Code example:

        Task { @MainActor in
            let youtubeDL = YoutubeDL()
            let (formats, info) = try await youtubeDL.extractInfo(url: URL(string: "https://www.youtube.com/watch?v=WdFj7fUnmC0")!)
            print(formats, info)
        }

Crash info

Thread 5: EXC_BAD_ACCESS (code=2, address=0x2800001100)

Crash occurs on:

Hook.m

Line 55:

    ret = realMain(argc, argv);
    NSLog(@"%s: realMain=%d", __func__, ret);

When the following is called in YoutubeDL.swift:576

pythonObject = try await makePythonObject()

Fully expecting this to be something I am doing incorrectly.

Downloading m3u8 file issue - only works from Xcode and json.decoder.JSONDecodeError

Hello,

I am encountering two issues with the argv for downloading an m3u8 file.

let argv: [String] = (
    url.pathExtension == "mp4"
    ? ["-o", url.lastPathComponent,]
    : [
        "-f", "hls-2176",
        "-S","ext:mp4:m4a",
    ]
)
+ [
    "--no-check-certificates",
    url.absoluteString,
]

1st Issue: App functioning only when running from Xcode

The download only works when the app is run from Xcode. If I close Xcode and reopen it, the download no longer functions. Here are the steps to reproduce the issue:

Clone the repository.
Run the app from Xcode.
Close the app.
Open the app manually - not by running the project from Xcode.
Attempt to download the sample URL using the provided argv.

I've included a screenshot of the issue:

2nd Issue: json.decoder.JSONDecodeError

While the app is running via Xcode and the download is complete, I encounter the following error:

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
startDownload(url:) Error Domain=App Code=1 "ERROR: Expecting value: line 1 column 1 (char 0)" UserInfo={NSLocalizedDescription=ERROR: Expecting value: line 1 column 1 (char 0)}

Steps to reproduce the issue:

Run the app from Xcode.
Attempt to download the sample URL using the provided argv.

Here are the screenshots of the second issue:

I would appreciate any help or guidance with these issues.

Merging never finishes

I've tried downloading the webm version of the demo video from the readme, but the merging process never seems to finish. I'm running the app on iPhone 12 Mini with iOS 15.3.1.

Dependencies could not be resolved

I cloned this repo, opened Xcode and pressed Run. This is the error i got:

Dependencies could not be resolved because root depends on 'youtubedl-ios' 0.0.2..<1.0.0.
'youtubedl-ios' >= 0.0.2 cannot be used because no versions of 'youtubedl-ios' match the requirement 0.0.3..<1.0.0 and package 'youtubedl-ios' is required using a stable-version but 'youtubedl-ios' depends on an unstable-version package 'ffmpeg-ios'.

ERROR: Postprocessing: ffprobe and ffmpeg not found. Please install or provide the path using --ffmpeg-location

I want to use it to extract mp3 only like below code:

let argv = ["-x", "--audio-format", "mp3", "--embed-thumbnail", "--add-metadata"]
try await yt_dlp(argv: argv)

but an error occured: ERROR: Postprocessing: ffprobe and ffmpeg not found. Please install or provide the path using --ffmpeg-location. I don't know the right way using FFmpeg-iOS and make it works. thanks for some help.

You have requested downloading the video partially, but ffmpeg is not installed

I'm facing this error when using example app:

You have requested downloading the video partially, but ffmpeg is not installed. Aborting

This is because of this line in python ffmpeg handler:

raise FileNotFoundError(errno.ENOENT, os.strerror(errno.ENOENT), args[0])

When I remove the line, it run through communicate function but after all it throws AttributionError:

Popen.__init__: <yt_dlp.utils.Popen object at 0x126d28160> (['ffmpeg', '-bsfs'],)
Popen.communicate: <yt_dlp.utils.Popen object at 0x126d28160> () {'timeout': None}
Popen.kill: <yt_dlp.utils.Popen object at 0x126d28160>
Popen.wait: <yt_dlp.utils.Popen object at 0x126d28160> {'timeout': None}
ERROR: 'Popen' object has no attribute '_Pop__args'

Please explain the python handler code, I have very little knowledge about python @kewlbear, thanks!
