Here is the command
ffmpeg -i Avideo.mp4 -i a.png -filter_complex "[1:v] rotate=-
30*PI/180:c=black@:ow=rotw(iw):oh=roth(ih) [rotate];[0:v][rotate] overlay=40:10" -codec:a copy sample.mp4

I changed c=black@ to c=0x00000000 and it worked for me.
ffmpeg -i Avideo.mp4 -i a.png -filter_complex "[1:v] rotate=-30*PI/180:c=0x00000000:ow=rotw(iw):oh=roth(ih) [rotate];[0:v][rotate] overlay=40:10" -codec:a copy sample.mp4
[The correct syntax is black@0 – Gyan]

Both codes work. I couldnt find the correct syntax listed on the documentation page.
It would be helpful if the documentation page provided examples rather than say this does that.
