I installed the IPCV module in a iMac under Sonoma 14.2.1, atomsLoad("IPCV") failed,

What I got :
→ p = setdiff(atomsGetInstalled(), atomsGetLoaded())
p =

“4.5.0” “I” “IPCV” “SCI/contrib/IPCV/4.5.0” “allusers”

→ atomsLoad(“IPCV”);

Hello,

Can you do the following on Scilab command line

edit SCI/contrib/IPCV/4.5.0/etc/IPCV_unix.sci

then change line 8

ffmpeg_libs = ["avutil"; "swscale"; "avcodec"; "avformat"; "avfilter"; "avdevice"];

to

ffmpeg_libs = ["avutil"; "swscale"; "swresample"; "avcodec"; "avformat"; "avfilter"; "avdevice"];

i.e. add “swresample” just after “swscale”. atomsLoad(“IPCV”) should run fine then.

I also updated the binary of the toolbox on Atoms.

Thanks for the report.

S.

Dear Stephane,

It now works perfectly well. Superb, I am grateful.

Many thanks to you.

Amicalement, Bernard
