I have the same issue too, although I'm not sure to what extent this is a sync/async issue or an exiftool issue. Any help would be appreciated.
What I'm trying to do is the following. I have a function getExifData
which calls exiftool's method to fetch the exif data. I then need the result of that to continue with.
getExifData = async () => {
const meta = exif.metadata('myfile.mp4', (err, metadata) => {
if (err) {
throw err;
return {};
} else {
return metadata;
}
});
return await meta;
}
myFunction = () => {
const exifData = this.getExifData();
const extension = exifData.category; // This needs the promise from exifData to be resolved
}
Because getExifData needs to be an async function, the second line in myFunction executes before the promise is resolved. I cannot make myFunction async, because the function that calls that would get the same issue.
What should I do here, if this is at all possible with exiftool?
Hi there, I am trying to dynamically get file details and i want to store it in db. When i am trying to run exif. it runs asynchronously so i couldn't get the exact mapping of file name and file metadata.
can you please help me out with this.
