Have you tried:
av::av_encode_video(vfilter = "scale=trunc(iw/2)*2:trunc(ih/2)*2")
Thanks @muschellij2 for your response. Now, I do not receive the same error, but the produced video does not work. I tried it on two different PCs. Below you find the output.

This works for me vfilter = "scale='bitand(oh*dar, 65534)':'bitand(ih/2, 65534)', setsar=1"
. I am naive to FFmpeg and do not know the difference, but it works anyway!
Thanks
Hello,
I am trying to convert many JPEG files into a video using the
av_encode_video
function. I received the following error message:I found some solutions (e.g. this and this) but no solution using R. Can this error message be solved using R?
The same simple code I used works fine for other image sets (with different image size).
Cheers, Ahmed
