Features

• Downloads videos from YouTube
  


• Allows you to choose the video quality
  


• Converts videos to various sound file formats (AAC, MP3, Ogg Vorbis, FLAC, WAV, Direct copy) using FFMPEG
  

Please tell me if it fails to download some videos. I haven't tried it with that many.

Usage
If you want to download a video:

1. Copy&paste the YouTube video link (form: http://www.youtube.com/watch?v=XX) into the topmost box
   


2. Click the "Download video info" button
   


3. Choose the desired video quality from dropdown menu
   


4. Click "Download video" and choose the location
   

If you want to download a video and convert it to audio file

1. Copy&paste the YouTube video link (form: http://www.youtube.com/watch?v=XX) into the topmost box
   


2. Click the "Download video info" button
   


3. Choose the desired video quality (this affects the audio quality, you can see the codec and bit rate for audio, too) from dropdown menu.
   


4. Choose the audio encoding you want using the other dropdown menu
   


5. Click "Download and convert" and choose the location for the audio file
   

You can also extract audio from already downloaded video (or you can convert audio files into another form) by choosing the target audio encoding from the menu and clicking "Open file and convert"

Requires following

1. You NEED to download FFMPEG ( http://ffmpeg.org/download.html / http://ffmpeg.zeranoe.com/builds/ ) and place ffmpeg.exe into same folder with this program.
   The reason I'm not redistributing FFMPEG myself has to do with licensing and possible patent issues.
   


2. .NET 4.5 Framework: http://www.microsoft.com/visualstudio/en...s#d-net-45
   


3. OPTIONAL: For higher quality AAC encoding, you need to download following: http://www.nero.com/enu/company/about-ne...-codec.php and put neroAacEnc.exe also in same folder with my program

Why not sharing the source in the download ?

I think this could interest some members..

He's using the FFMPEG wrapper, which pretty much takes care of the conversion functionality, so that leaves the YouTube downloading functionality and other miscellaneous things like the GUI. So I don't see much use in releasing the source.

Anywho, thanks OP for the nifty tool, I assume you're using an online service for the youtube download feature?

The download feature is done in the code, there is no online service used.

I did not see you credit this guy.. Which is where most of your code comes from... https://github.com/flagbug/YoutubeExtrac...esolver.cs

Its almost an exact rip..

[Immortal]

thank you for this, I really need a faster alternative to those web services that do this. Do you plan on making this opensourced? that would be awesome!

It's not similar at all... I haven't ripped anything and you can even see that my code isn't even close to that if you use Reflector.

I did use reflector hence how i saw your code, i noticed some VERY similar layout, you may have changed a few things and added an option to download using FFMPEG, but the code looks almost exact at certain parts..

Also why did you not include the ffmpeg in resources? would be easier. It's what i did in my own version. Mine is totally different tho, as i had help from IDB.

If I'm wrong i appolagise. I just copied some of your code into google and that was the result. So it must be exact in the parts i copied or i would not of got an exact result.

I posted the class. Everybody can draw their own conclusions on if this is ripped or not.
And the reason for not including FFMPEG is that it might be against the license / patent rules (patent holders of some codecs can demand money for distributing their codecs)

Oh god 0xDEADDEAD's source looks so much like the one on the github repository.

Please note...

I also said "If I'm wrong i appolagise. "

And i can see i am wrong...No need to be a dick about it. I just asked a question, it got answered..

[hgdfhsdgdfgdfh]

Just a tip I figured out.
If you want to get the best sound quality possible, you should obviously download the video with the biggest audio bitrate. The video resolution doesn't matter. So for example if you have a video with 1080p and 720p (both have audio bitrate 192kbps), you can download the 720p one. And when it comes to the target audio format, for the best quality you should select "Copy (copy audio to container specified by file extension)" from the dropdown menu. If the video you are downloading has AAC sound, set the file extension to ".m4a". If the video has Vorbis sound, file extension should be ".ogg". By using this "Copy" option, you will get the original audio from the video instead of recompressing it again (it can lead to reduced sound quality even if you choose a high quality codec)

[hgdfhsdgdfgdfh]

Update: Uploaded a new version with more detailed information about audio codecs. Also moved the most HQ (Copy audio) audio 'encoding' to be the default one on the list.
Download: http://hostr.co/VLePQbxZaf5F

Note: FFmpeg is still required: http://ffmpeg.zeranoe.com/builds/ (you need ffmpeg.exe in same folder with my program)
You can also download http://www.nero.com/enu/company/about-ne...-codec.php and place neroAacEnc.exe file into same folder with my program (just as you do with ffmpeg.exe). Note that this step is optional, but recommended if you want to encode high-quality AAC files.
