Option to Flip Videos Horizontally

[Pesala]

Maybe someone knows how to do this already, but it would be good to have a way to flip videos horizontally.

You may have noticed some videos are reversed before uploading.

if you want to flip a local video file use ffmpeg

no, example?

@iAN-CooG I mean that the video should be flipped back to normal in Vivaldi.

@Pesala that video was flipped prior of uploading, probably just to avoid being automatically detected and removed due to copyright as explained in the comment.

VideoMirror - Chrome Web Store
Video mirror (left-to-right) on any page (including Zoom, YouTube, Vimeo, Twitch, Google Meet, etc.)

@claudio That is exactly what I meant. Now we just need a switch in Vivaldi so that the extension is not needed.

Anyway you can use script on youtube:

just change in it

// @match           *.youtube.com/watch?v=*

to

// @match           https://www.youtube.com/watch?v=*
// @match           https://youtube.com/watch?v=*

if it doesn't work.

@Asires it seems it can't be added as a user.js in the extensions page, does it require greasemonkey?

[Asires]

@iAN-CooG no, it requires Violentmonkey
