How can a user/client get a screenshot from stream and save it in local device ?

Hey there!

You can definitely set up a blueprint to take a screenshot then send it to a connected peer through Pixel Streaming. The image below shows the required configuration.

Note: the “Screenshot Number” is a simple integer variable that was added to the BP graph.

Furthermore, you’ll need to take a look at this line below in the infrastructure, as it current sends, but does not auto-download the file. You can modify it here:

github.com

EpicGamesExt/PixelStreamingInfrastructure/blob/master/Frontend/library/src/Util/FileUtil.ts#L97


      
                      /**
                       * Example code to reconstruct the file
                       *
                       * This code reconstructs the received data into the original file based on the mime type and extension provided and then downloads the reconstructed file
                       */
                      const received = new Blob(file.data, { type: file.mimetype });
                      const a = document.createElement('a');
                      a.setAttribute('href', URL.createObjectURL(received));
                      a.setAttribute('download', `transfer.${file.extension}`);
                      document.body.append(a);
                      // if you are so inclined to make it auto-download, do something like: a.click();
                      a.remove();
                  } else if (file.data.length > file.size) {
                      file.receiving = false;
                      Logger.Error(`Received bigger file than advertised: ${file.data.length}/${file.size}`);
                  }
              }
          }
          
          /**
           * A class that represents a template for a downloaded file

Let me know if this gets the job done!

Thank you for your reply

Also the backend PS services are third party provider.

i have added all this things in my project but when i try to run this on local host the fontend got all white and blank

@TejasSaran If your frontend is all white and blank, you are likely running into a javascript issue.

I’d check the developer console (Ctrl + Shift + I on Chrome) and check the logs. Those logs should contain the error.
