The chrome developer console in your screenshot shows a code file and line number. Could you click on those and send me screenshots of the code? That would help me track down where the issue is.

They are very long lines of code, so it is hard to tell where the issue. The code can be pretty printed by clicking the { } button on the very bottom left of the developer tools. If you could get me new images of the code being pretty-printed, I might be able to tell what is happening then. See the image below for the location of the button:
I am curious, can you replicate the issue at this demo link? It is running the exact same sample: https://webviewer-video.web.app/

Thanks for the files. I was able to track down one of the extra requests and I am going to fix it. I am not sure about the third fetch. I will fix the first one and you can test again.

I have another question, are is the webviewer-video app running from your server or client side?
Could you also send me a picture of the Headers of the first 200 request for the video. I am interested in seeing the ‘General’ section and the ‘Request’ section.
If you are running this from your server and the link is public then you could just link to me and would be the easiest. Thanks!

It is running from client side.

The first fetch with status 200. Is a fetch head request for the metadata of the video and is pretty small. The are two other fetches for the full video. One is to generate the waveform and the other is to determine the real frame rate of the video file. Once this data is cached in local storage, then these fetches will no longer be needed.
We can potentially refactor these fetches to be only one fetch. But it proved to be a little bit complicated than I thought and will take some time.
As a temporary workaround you can disable one of the fetches by removing the ffprobe folder from the public folder of the webviewer-video-sample. This will disable getting the accurate frame count for the video but it won’t affect too many things. Alternatively, the fetch for the waveform can be disabled by disabling the audio capabilities. This can be done by not passing in the AudioComponent prop to initializeVideoViewer.

I understand that it works to get 61MB each for waveforms and video files.

All right.
As a side note, Product development uses only video components.
The remaining unclear point is that I got it again after pressing the play button.
If you are only using the video component then you can disable it by commenting out the property mentioned in my previous reply. That will save one fetch.
When you hit play, the browser handles the streaming of the video. Those requests are partial requests and we are not in control of them. There is no source code line in the initiator column. They originated from the browser.
It is strange that the time column values are so large. Is the video not playing well? 20 seconds for 500kb seems extreme. Maybe your internet connection is slow?
