[solved] OpenCV videoWriter not writing

[sfphynx]

Hello!

I was trying something on gamma : drawContours and videoWriter.

The writer does write, but the file becomes 3 times bigger, (for a 20 second video, it is like 1.5Go file!!!), and once done the writing is done, I cannot open it (VLC says RAW format)

What am I doing wrong???

Is there a way to output the video, from skia for example?

Note to myself. And to anyone who has trouble exporting the video file with videoWriter:

In the help patch for “batch process video”, the file name extension should be .mp4

Mine was a copy of the original file in .MOV format. That causes the error!!
