Next, we get the StreamQuery Object, some Youtube videos are not available to download and will return an empty StreamQuery Object.We use streamlit’s image() method to display the image. Then we get the information about the video such as the Thumbnail Image URL, Title, Length of video, and Average Ratings.If we create a Youtube object with an empty URL, it will give an error First, we check if the user has input the URL.St.subheader("Sorry, this video can not be downloaded") Video.filter(only_audio=True).first().download() '''.format(yt.title, yt.length, yt.rating))ĭownloaded, download_audio = False, Falseĭownload_video = st.button("Download Video")ĭownload_audio = st.button("Download Audio Only") Note: The filter() method returns a StreamQuery Object, one of the 5 methods below the filter() method will need to be used to return a Stream Object which we can download. get_by_itag(itag): If you want a specific stream object, you can pass it’s itag.get_lowest_resolution(): Returns progressive stream object with lowest resolution.get_highest_resolution(): Returns progressive stream object with highest resolution.last(): Returns the last stream object in the StreamQuery Object.first(): Returns the first stream object in the StreamQuery Object.This method returns a StreamQuery object. Setting only_audio to True will return the streams with only audio components and similarly setting only_video to True will only return the video components which do not have an audio component. Setting progressive to True will only return the progressive streams. res is a string while the others are boolean. filter(res , progressive , only_audio , only_video): This method returns the list of streams based on the value of the parameters passed.It has quite a few helpful methods to help us get a stream object. Step 5: Chosing a Stream Object to DownloadĪs mentioned before, the YouTube object has an attribute called streams. If no path is provided, the file will be downloaded in the same folder as your python script.

The legacy streams that contain the audio and video in a single file (referred to as “progressive download”) are still available, but only for resolutions 720p and below.Įach stream object has a download() method which takes in the path as an optional parameter. Therefore they are only the video components.Įach stream object also has a res propery which is the resolution of the video. Both only have the vcodec property and do not have the acodec property. On the other hand, Stream Object 3 and Stream Object 4 have progressive set to False implying it is a DASH stream. Both of them a vcodec property and a acodec property referring to video and audio respectively. Stream Object 1 and Stream Object 2 have progressive set to True implying it is a progressive stream. If you inspect the Stream object, you will notice each object has a boolean property called progressive. The video and audio components will have to be download separately and then merged together using a software. DASH streams are used to download videos in high resolution. A progressive stream has both the video and audio components while a DASH stream only has one of them. There are two types of streams Progressive and Dynamic Adaptive Streaming over HTTP (DASH). We will need to choose one of the streams and use it to download our video/audio.

I have also truncated the output since it is pretty long. Step 4: Understanding the Stream Object print(yt.streams) We will be discussing them in the next step. The Youtube Object also has an attribute called streams. This URL can be used by streamlit’s image() function to display an image. thumbnail_url: The URL to the thumbnail image.

The YouTube Object has many useful attributes, some of them are listed below The constructor of Youtube object requires the URL to be passed in as a parameter. I will be working with the following URL Step 3: Getting the Data for the Youtube videoįirst, we will need to create an instance of the YouTube object we imported from pytube. Every time the user types in an URL and hit’s enter, the app is re-run and the text_input() function will return the input URL We will need to store the URL inside a variable. Both of them take a string as a parameter and display it.įor the user input, we will use the text_input() function. We will be using streamlit’s title() and subheader() functions for the text.
