Youtube v3 Api Get video by ID

Question

How can I get a single video by its ID using the Youtube API v3.

So far I've only come across search mechanisms and other, but not specifically one to get a single video, the code that I have currently is:

def youtube_search(q, max_results=1,order="relevance", token=None, location=None, location_radius=None):

   youtube = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION, developerKey=DEVELOPER_KEY)

   search_response = youtube.search().list(
    q=q,
    type="video",
    pageToken=token,
    order = order,
    part="id,snippet",
    maxResults=max_results,
    location=location,
    locationRadius=location_radius

   ).execute()



  videos = []

  for search_result in search_response.get("items", []):
    if search_result["id"]["kind"] == "youtube#video":
        videos.append(search_result)
  try:
    nexttok = search_response["nextPageToken"]
    return(nexttok, videos)
  except Exception as e:
    nexttok = "last_page"
    return(nexttok, videos)

But I've realized that this method is not efficient but rather wastes time and resources. How can I go about it?

Answer 1

Configure your api in Google play console and playground. Get api key and access token then call this API to get video by Id.
You can test from here as well link

GET https://www.googleapis.com/youtube/v3/videos?part=snippet&id=vuKRKt7aKpE&key=[YOUR_API_KEY] 

Authorization: Bearer [YOUR_ACCESS_TOKEN]
Accept: application/json

Answer 2

To access a specific video in Python can be done by video() method instead of search(), and with a parameter id in list() method. id is an argument that can be found in an URL of your Youtube video in format https://www.youtube.com/watch?v={video_id}[&{otherParameters}={values}] (for an example https://www.youtube.com/watch?v=qEB0FIBoKAg&t=15s). In your URL, the value of v (after "=" symbol) is the ID of the video you are currently watching. The "&" symbol means to add other arguments (here, t is "start time of the video" and starts at 15 seconds).

How I do it in a code is:

...
# Create API service
serv = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION, developerKey=DEVELOPER_KEY)

# Make request. part must be "snippet", id is your video, and maxResults is optional
req = serv.videos().list(part = "snippet", id = video_id, maxResults = 1)

# get the JSON file (can be accessed as a dictionary)
response = req.execute()

# Access the (standard) thumbnail (URL)
sd_thumbnail = response["items"][0]["snippet"]["thumbnails"]["standard"]["url"]

# If you want other resolutions than "standard" you can change it into "default", "medium" or "high"

print(sd_thumbnail)

This program will print:

https://i.ytimg.com/vi/qEB0FIBoKAg/sddefault.jpg

It's format is https://i.ytimg.com/vi/{video_id}/{file}.jpg Instead of file here can be "default", "mqdefault", "hqdefault" and "sddefautl".
