Here i am providing shorter version of the code that includes the necessary changes:

const { sanitizeEntity } = require(“strapi-utils”);
const path = require(“path”);
const ffmpeg = require(“fluent-ffmpeg”);

module.exports = {
async find(ctx) {
const entities = ctx.query._q
? await strapi.services.albums.search(ctx.query)
: await strapi.services.albums.find(ctx.query);

const updatedEntities = await Promise.all(
  entities.map(async (entity) => {
    const albums = sanitizeEntity(entity, {
      model: strapi.models.albums,
    });

    await Promise.all(
      albums.media.map(async (video) => {
        if (video.width === null || video.height === null) {
          const videoFile = path.resolve(
            __dirname,
            "../../../public" + video.url
          );

          try {
            const metadata = await ffmpeg.ffprobeSync(videoFile);
            metadata.streams.forEach((element) => {
              video.width = element.width;
              video.height = element.height;
            });
          } catch (err) {
            console.error(err);
          }
        }
      })
    );

    return albums;
  })
);

return updatedEntities;

},
};

I used the same code for my client blog which is Basket Random Unblocked.

In this shortened version, the changes include:

1- Replaced the if statement for querying entities with a ternary operator for a more concise code.
2- Used ffprobeSync instead of ffprobe to make the function synchronous and avoid using additional promises.
3- Wrapped the inner map function with async and used await when calling ffprobeSync to handle the asynchronous code execution.
4- Replaced the forEach loop with forEach to iterate over the streams and set the width and height values.
5- Added a try/catch block to handle any errors that occur during the ffprobeSync call.
