• Attempting to use recursion, why does my code only download 4 videos and exit ?

  16 avril 2024, par Andrew Atwood

  I am attempting to download videos from an API that I have access to. This should loop through all of the videos that were returned from the API call, save them to disc, use ffmpeg to verify the meta data from the API (this step is necessary because the API is sometimes returning incorrect information), then save attribution information and continue on if no error. However, my output from the below code is simple this :

  No errors, no exit code. Just stops running. I've walked through the process in my head a few times, and I can't figure out why it only gets called 4 times. Would anyone have any insight as to where I could try troubleshooting ?

  


  Code Here :

  


  require("dotenv").config();
const axios = require("axios");
const concat = require("ffmpeg-concat");
const fluent = require("fluent-ffmpeg");
const fs = require("fs");

const PEXELS_API_KEY = process.env.PEXELS_API_KEY;

const SUBTOPIC = "animals";

const URLBase = `https://api.pexels.com/videos/search?query=${SUBTOPIC}&per_page=80&size=medium&orientation=landscape`;
let rVideos;
let videosToConcat = [];
let duration = 0;
let current = 0;

const fetchVideos = async () => {
  const response = await axios.get(URLBase, {
    headers: {
      Authorization: PEXELS_API_KEY,
    },
  });

  return response.data.videos;
};

const writeVideoToDisc = async (videoObj) => {
  let found = false;
  videoObj.forEach(async (file, index) => {
    if (
      found === false &&
      file.quality === "hd" &&
      file.width === 1920 &&
      file.height === 1080 &&
      file.file_type === "video/mp4"
    ) {
      found = true;
      let writer = fs.createWriteStream("raw/" + current + ".mp4");
      let streamResponse = await axios({
        url: rVideos[current].video_files[index].link,
        method: "get",
        responseType: "stream",
      });
      streamResponse.data.pipe(writer);

            ) {

                  console.log(
                    `Saved 'Owner: ${rVideos[current].user.name}; Owner URL: ${rVideos[current].user.url}' to ${SUBTOPIC}.txt`
                  );
                  if (duration < 600) {
                    console.log(duration);
                    console.log(current);
                    current++;
                    writeVideoToDisc(rVideos[current].video_files);
                  }
                }
              );
            }
          }
        });

    }
  });
};

const main = async () => {

  console.log(rVideos.length);
  await writeVideoToDisc(rVideos[current].video_files);
  console.log(videosToConcat);
  // concat videos together
};
