Videos are not running

Question

Hi Naimish

I have below code. What is happening . It opens 1,2,3, video but only last one is run. I want first video should run then second,third and so on.

foreach (var video in videos)
{
    _driver.Navigate().GoToUrl(video);
    await Task.Delay(1000); // This is just to simulate the time it takes to play the video
}


var videos = new List<string>
{
    "youtu.be/f7V5l5-EU",
    "youtu.be/WI-KwauaM",
    "youtu.be/_KOUp4WBo0",
    "youtu.be/5CPMILQrE"
};

The code you’ve written is opening each video URL in the same browser tab one after another with a delay of 1 second ( await Task.Delay(1000); ). However, it’s not waiting for each video to finish before moving on to the next one. That’s why you’re only seeing the last video play. To have each video play fully one after the other, you would need to know the length of each video and delay for that amount of time. Unfortunately, the WebDriver does not have the capability to control or get the duration of a YouTube video. A workaround could be to use the YouTube API to get the duration of each video and then delay for that amount of time. However, this would require you to register for the YouTube API and handle the API responses. Here’s a rough idea of how you could implement this: foreach (var video in videos) { _driver.Navigate().GoToUrl(video); // Use YouTube API to get video duration var videoDuration = await GetYoutubeVideoDuration(video); await Task.Delay(videoDuration); } In the above code, GetYoutubeVideoDuration(video) is a hypothetical function that you would need to implement. It should use the YouTube API to get the duration of the video, and return that duration. Please note that this is just a workaround and might not work perfectly because of factors like buffering time and internet speed. Also, using the YouTube API might have its own costs and usage limits. You should check the YouTube API documentation for more details. Thanks

The problem you are facing is due to the asynchronous nature of the code execution. The loop you have written navigates to each video URL but does not wait for the video to start playing before moving to the next URL. To ensure that the videos play sequentially, you can modify the code to wait for each video to finish playing before moving to the next one. You can achieve this by using a synchronization mechanism like Task.Delay combined with await to introduce a delay between navigating to each video URL. Here's how you can modify your code: var videos = new List { "youtu.be/f7V5l5-EU", "youtu.be/WI-KwauaM", "youtu.be/_KOUp4WBo0", "youtu.be/5CPMILQrE" }; foreach (var video in videos) { _driver.Navigate().GoToUrl(video); // Please find the video length, convert it into seconds, and then pass it into the method below. await Task.Delay(10000); // Adjust the delay time as needed to ensure the video has played } By adding a suitable delay after navigating to each video URL, you can ensure that the videos play sequentially in the desired order. Adjust the delay time according to the length of the videos to achieve the desired playback sequence.
