Screenshots
Link to video (Can't attach because it exceed GH file size limit)
But there is most important frame:
Desktop (please complete the following information):
- OS: Win 11
- Version 2.40.1
- ffmpeg 6.1.1
Additional context
The video was shot when I set the latest version of ffmpeg 6.1.1 but I've met this bug with in box ffmpeg 4
Yeah, there's an issue when the ffmpeg encoder produces duplicated frames. The returned frame count number is such case can be greater then one that was passed. We should consider reducing the frame number by the duplicated ones. I'll create a PR to fix this.
Ok, this is a bit more interesting that initially anticipated.
One of the output lines from ffmpeg:
frame= 1 fps=0.0 q=32.7 size= 0kB time=-00:00:00.04 bitrate=N/A dup=12 drop=0 speed=N/A
So it's not just a matter of removing the dup's as that would produce problems on the other end. Values below 0%. Investigating.
