If you need other features, have suggestions, just rewrite a review;  
I will do my best!
If extracted files disappears from Files app, restarting the device may fix the issue.
If you cannot extract the audio, restarting the device may fix the error;
if restarting does not solve the error, try moving the video from Photo app to File app,
then open from File app.
if these workaround do not fix the error and you can send me the source video or
a downloadable link from the contact mail, I would do my best to debug.
If you like the app, please review or leave a comment.
