Please give me some advice on video watermarking and transcoding. I hope you can give me some advice.

I want to upload the video now, but now I encounter two problems,

A: How to add watermark to videos that have been uploaded to Qiniu? Now I only know how to add watermarks to videos when transcoding, but I don’t know how to add watermarks to videos? Or is it possible to add some watermark parameters when uploading videos, so that the uploaded videos already have them? Watermark effect?

The other thing is, that video is transcoded, how do I monitor the transcoding status? Because the current effect I want to achieve is: if the transcoding is successful, continue running, otherwise wait until the transcoding is successful,,,

I also hope that friends passing by will nominate one or two, thank you! ! ! ! ! ! ! ! ! !

First one: It cannot be transcoded separately, now it is merged together.
Second: For asynchronous notification, do not make it synchronous.
I am also currently working on Qiniu video. It seems that taking screenshots of the video can only be done asynchronously. How do you do it, buddy?
