Thanks a lot for helping....

Hello, i think this is a new bug on the youtube-dl-gui.

youtube-dl version: Lasted.

https://imgur.com/a/swArCp0

Cheers.

During batch processing, the thumbnails are not embedded in the file.

Is there anyway to add support for BeatStars.com? e.g. https://www.beatstars.com/beat/circumstances-4282656 and/or https://bsta.rs/6cfb3f59
P.S. Is there anyway to donate to this project?

Pleasee add option choosing resolution for video
Program always download in best. For peophe who have limited internet, or less conection it is not good solution. Please add option asking about resolution from avaible. Options in the GUI. I do not like the command line.

While using youtube-dl-gui with an older version of youtube-dl- 2020.01.24 I got the following error message:

Feel free to copy + paste this entire text wall into a new issue on Github

screen:

When I updated youtube-dl-gui to the latest version- 2020.02.16, I didn't get this error any more. Yet I decided to report the problem as it might provide some useful information for you.

I am using youtube-dl-gui on Windows 8 x64.

Why 2.23 saves audio in aac, while its original extenstion (as it is in original video file) is opus.
I compared it with 2.22 version.. So it does it in original opus...

@murrty

I have some proposal for improvements

At first startup detect OS language an set the program in the sanme language
At first startup the program check OS language (ex. Italian) and if available set the program with the same language.

Infact there are some warning that I beleieve that could be appear in local language (ex. Italian).

Bigger dafault width for main window
At first run the width for main is window is too small.
Please setup a larger widt as default for main window
I know that you can change it but for me should be better to have from first run a bigger width.

There are two strings (lblformat and ebst) that should be added to the strings that can be translated.

Store setting about audio/video format quality and type
The program If I select ex for video MP4 and MP3 should store my settiings and not like now at next startup reset it to "best".

Swap postition about file type and quality
For me the right order of selection is first file type (ex. MP3 or MP4) and then file quality.
Then vicevesersa like now. My prosal is like this.

I was about to complain that the program does nothing after you click yes on the legal agreement. Then I tried clicking No and it actually worked. My download was youtube-dl-gui-2.12 from the releases page.

Hi,well the title says it all:

Cheers.

I do not know what's the problem.

Thx for add quality option select :)
If you can add please suport download multiple files (eample add link to file witch multiple YT urls)

@murrty

Please check the screenshots.

Please update language files and fix GUI issues.

" -f \"bestvideo[height=1080][fps>=48]\" would only download 1080p60fps videos, nothing else. Proper code should be " -f \"bestvideo[height<=1080][fps<=60]\" to fix

the heights are fixed with commit 2d324f8, but fps is still being worked on. manual compiling required until an update is sent.

When l try download audio (pic1) and select/deselect box "Use VBR", in dropboxes "Quality" and "Format" variants added every time (pic2, pic3). So if i need mp3 vbr V5 i must select (pic4), arguments (pic5).

I tried adding a custom paramater, this one:
-f "bestvideo[height<=480]+bestaudio/best[height<=480]"

I get an error in the command window but the window closes immediately so I can't read what it is. Also, I checked Save errors as error.log in Settings but no error.log is created.

i dont know why but for me only 1.651 work properly, other further version only show first run notification

How to merge video and audio file in two one?
I see Convert tab fully useless. Is it only for reconvert not for merge?

In your version the video file is saved into two sub folders below my selected download path, named "video", and a level above that named after the original domain. I.e. [Path]videosite.com\video\video.mp4

How can I revert it to the old behavior where no sub folders were created?

1. When using the "Extract audio" option the text in the file browser does not match.
   It says "remove"
   

2. When extracting an AAC audio track from an MP4 video to AAC format, it does not demux (extract) it, but recodes it.
   FFMPEG can simply dump the data into a compatible container. This would be preferable because there is a dedicated convert tab.

Anytime I try to set the folder where ffmpeg and ffprobe are located, it just clears them whenever I exit the settings window, even when I click save prior. It stays when I click Use static ffmpeg, but when I try to convert a file it just says it's null as if it hadn't anyway. From downloading, it's just a regular "ERROR: ffmpeg or avconv not found. Please install one." message Here's the log from converting

how to use youtube-dl -f worstvideo+worstaudio in custom arguments youtube-dl-gui?

Can you add an option to force VP9 or H264 when downloading?
Same thing for choosing audio would be great as well.

I've downloaded the portable version: youtube-dl-gui.zip v2.12.

After running youtube-dl-gui.exe, i'm shown the following message:

after clicking "Yes", I can see in my task manager, that the program just closes, and nothing else happens.

I have ffmpeg on in my PATH (And for good measure, I tried downloading ffmpeg 4.2.1 x64 static, and placed it besides youtube-dl-gui-exe)

I have manually downloaded v2020.01.01 of youtube-dl. both the file youtube-dl and youtube-dl.exe, just to make sure, as I didn't exactly know which one was the right one.

Also, I have .NET v. 4.8.03752 installed on my machine. Running Windows 10 64-bit v1909

Why does my download stop before it is finished? and how to auto resume download?

As of youtube-dl-gui version 2.2, support for multiple languages was added to the program which allow non-English speakers to use the application given that the language file is present... which is where I need help from anyone willing to participate in building this program. I will appreciate it a tremendous amount for anyone helping with translating.

The default English template used within the program is located here (raw link here). This is the template that should be followed when translation.

Modifying the localization is like editing an .ini file, the key is located to the left of the equals = sign, and the value is to the right. An example translation key would be like this: btnRedownloadYoutubedl=(Re)download youtube-dl. Any values that contain an equal sign will show the equal sign as well, unless issues arise where this is not respected. More information about translating can be found within the English template.

There are 2 known places that are not translatable:

• The major name on most forms and dialogs youtube-dl-gui
• The lower text on frmAbout (whatever it may be)

When forking the repository to add or modify the languages, be sure all localization files are location at the Languages folder in the root of the master repository (if forks are present). Be sure to include your name in the localization file when translating for credits with the translation. If you do this, do not remove other peoples' names either as it's an aggregated list of people who helped translate that language.

Found a value that isn't represented? Open an issue with details about it. If it is acknowledged as "not translatable", the issue will be closed as wontfix.

I tried to save the download location to somewhere other than my downloads folder, but it always resets
I also tried to edit the downloadPath and FirstTime in settings.ini but it still resets to default
I am using windows 10 with .NET v4.8.04084

youtube-dl-gui saves its configuration file (user.config) in AppData:

C:\Users\User\AppData\Local\youtube_dl_gui\youtube-dl-gui.exe_Url_axgmtcpdpseegko5bud4bxc054vq5g0j\2.0.0.0\user.config

I would like to suggest an option configuration file to be saved in program folder (next to executable file- youtube-dl-gui.exe) which will mean that youtube-dl-gui is running in portable mode.

Portable mode can be implemented in many different ways, I will suggest just few:

1. command-line argument - if the executable (youtube-dl-gui.exe) is started with a specific parameter, for example youtube-dl-gui.exe -portable, configuration file (user.config) is saved in program folder;
2. configuration file - when youtube-dl-gui starts it checks program folder for configuration file (user.config) and if it is there the program uses it;
3. option in settings - new check box- Portable mode (perhaps in General tab), which, if selected, forces the program to save configuration file (user.config) in program folder;
4. portable flag - specific file in program folder (for example portable without extension or portable.txt) triggers portable mode, when youtube-dl-gui starts it checks program folder for such file and if it is there configuration file (user.config) is saved in program folder;

Any of these methods would be fine for me but I prefer option 2- when the program starts it checks its program folder for configuration file (user.config).

I prefer to use programs running in portable mode- they are easier to backup, they can be easily transferred from machine to machine with their settings, they are handier for testing.

I suppose that the implementation of portable mode would not require too much work.

Some issues about v. 2.25.1 (the version should be 2.25.1 - not 2.251)

Please change defualt main window width (at first run).
I know that user cam set a size and save but my request is about to set a default first run value for main window width.

Move these items few down to have mroe space vs second box.

Click on this link point to a not existent web page.

This and ny other drop down file list is untranslated.
If you can add this item names (realted not only this window but at all windows) in translation strings.

Firstly thanks for attempting to fix #39 but 2.24 only has an option to press ok, with no option to remember skipping the prompt.

You mentioned that you prefer people use the batch form but I use a userscript I made to pull all video stream urls from a website and copy to clipboard, line-separated as per how you batch load from txt file. It's currently impossible to paste from clipboard more than 1 link in to that form (I don't really care too much about this though since I use the other method).

Another thing that isn't too great when doing batch downloading is if you mess up the custom commands or the cookie for the site has expired and the download fails, if you press exit button it will just close that window and then start the next download (which will also end up failing) so you need to close all windows from the task bar to stop it. It would be nice if exit could stop the current download and every subsequent download thereafter because currently there's no difference between pressing exit and pressing the X button.

Another thing I would like to see would be options to set custom arguments within the txt file used for batch downloads (though this could also be made as site profiles within the main app). Rather site profiles

After initiating the batch download, the download status window isn't brought to the front. This is more of an issue when skipping the prompt windows as it can be hard to tell if you actually started the download or not.

please add proxy option and sustitles, ..... recommendation

Currently if you want to use the batch download option you first get prompted with a message on how to use it which is probably helpful the first time you use it but nothing but an annoyance after that, it can either have an option in the prompt to never show again or an option to disable in settings.
Once you've selected the file you get prompted with another message which blocks the download from starting. This message just tells the user that it can take a long time and is completely useless (it could be put into the first prompt)...

Please enlarge width of "Main" and "Settings" windows.
Some strings not have enough space for not English language.

Please check the screens

I already create a PR for Italian language.
Pelase merge it before to fix the GUI.

how to edit youtube playlist?

Edit: Actually it's super simple, the problem occurs with apparently all Reddit videos and I'd overlooked the "fix Reddit videos" checkbox in the settings. When it's turned on, Reddit videos cause error spam and come out bad. With it turned off, they come out good. Looks like whatever it was fixing isn't true anymore.

When https://www.reddit.com/r/funny/comments/daefhv/guy_wakes_up_in_the_wrong_house/ is downloaded with the default options Download type: video, Quality best (or Quality 480p or 360p, the other two I tried), the command line window scrolls through a bunch of yellow errors about "Non-monotonous DTS". The download completes but the video stops or gets out of order at several points.

The video is visibly malformed in some way even when viewing on the Web (big encoding-fail color blocks), but it comes out fine by either:

1. using the same youtube-dl.exe that GUI is using, from the CLI, with no options or
2. Changing the Download type to Custom with a blank arguments field

Something in your default arguments is apparently breaking something, or at least stopping it from being automatically fixed. Is there a way to capture the generated command line and returned text for further troubleshooting?

@murrty

Seems that youtube 2.25 don't save language settings.

Won't run on XP 32?

Youtube-dl has been heavily uncommitted for the past few months, and there's been a new fork that's kind-of taken on the reigns. Wondering if it would be possible to perhaps give the option of supporting that instead of the original one?

Hello i discovered if you change the download folder, the program make a automatic folder called video.

Change the folder:

And go to path:
