Thumbnail is an image generally picked up from the video itself which is the representational image or short descriptive image of the video.
Every video on Youtube has some description which gives information about the video and some hyperlinks to the associated blogs or websites etc. This description can be viewed by using the description property of the YouTube object myVideo. The YouTube object myVideo has this property called views which returns the number of times the video has been viewed. This property might not work correctly because of the changes in the Youtube API recently.
So you have to change the code in the pytube library. All the changes that should be made are listed below in a separate section. Just like the views property, rating property might also through some errors.
If the value is false then the video is not age restricted and if its true then the video is restricted. These errors are encountered when we try to create a YouTube object with some youtube link and the link doesn't gets identified as a valid link.
This happens because the regular expression used to identify YouTube links could not identify the URL as a valid one, that's why we need to change the code in the library. To know where the library files are installed in your system, open command prompt and type the following command. After executing that command you will get the location of the library. Open the folder, and edit the cipher. It's better to store a copy of the original file somewhere so that if we end up making some wrong changes we can always use the backup file.
Like we mentioned before as well, due to some changes in the YouTube API you might get error while using the views property. Whenever we use the views property, this error occurs because of the old API call made to Youtube by pytube library.
Go to the line number where the error occurred, now replace that line with the following code. Currently there is no fix for this error because the Youtube API is not giving any information on the rating because it is deprecated. Download the updated library files that are fixed from here: Library Files With errors Fixed or update the files yourself as explained above. Now that we have created a simple program and are quite familiar with the basic functioning of the pytube library, its time to take a deep dive and understand how we can actually use this library to download and stream the videos.
Now let's talk about the StreamQuery Object, pytube library provides two types of streams:. YouTube uses DASH Stream and that is the reason why it automatically adjusts the quality of the video streamed to your device based on the network speed. Whenever we use the streams property on a YouTube object it will return a StreamQuery object, which you can use to find all the streams available for the video you have provided the link for.
With this StreamQuery object, we can perform different operations and the most basic one is streamQuery. See the code below:. In the output, we can observe a list with several streams, but I am showing only a few of the list items.
Observe that each stream is just like a tag in HTML with different key-value pairs. Every stream has a different set of attributes based on which the quality in terms of resolution and codecs differ:.
When first is accessed on the StreamQuery object myVideoStream , it will return the highest quality stream available for a given video which consists of the audio codec also.
Similarly, when we use last on the StreamQuery object it will return the audio stream because it is the lowest quality available.
Whenever you get the details of a single stream you can download that stream to your current working directory using the download method.
If you want to download the file to a specific location or path on your system, you have to just specify the path where you want to store the file as the parameter to the download method. As you have seen different keys in the stream like resolution , fps , codec etc. We can use these keys as filtering mechanism on the StreamQuery object to retrieve the desired stream s and then retrieve single stream by using methods like first , last etc.
Similarly, we can use type parameter in the filter method, using which we can get either stream of type audio or of type video only.
After using the filter method you can use any of the methods that will retrieve a single stream first , last etc. If you are looking for the code to download a video easily, here is the magical one-line code to download the video with the highest quality available to the current working directory. Here's the link to the GitHub repository where you will find the code for the above programs and usage of different properties:.

Then, get the appropriate extension and resolution of the video. You can set the name of the file as your convenience, in another case original name will be kept. After that, download the file using the download function which has one parameter which is the location where to download the file. Depending on the speed of the connection, time taken to execute the program varies.
In case you wish to download the number of files, go with the next case. Downloading multiple videos The basic task of downloading the multiple videos is same as downloading a single video.
We can use a for loop for downloading the video. One can use file handling for keeping the all the links in a file which needs to be downloaded. Download multiple videos using File Handling Using file handling, we can open the file which has the group of links in it. Traversing every link of a text file and applying the very basic video downloading program is done here.
Otherwise it will raise an error. In this case, only one video will be downloaded. You can modify the names everytime using another array of names. Connection Intruption in between will also raise an error and video will not be downloaded in that case. This article is contributed by Rishabh Bansal.
