YV12 to RGB

[stephen22]

I would be so grateful if someone could tell me how to do this conversion, so I can get jpegs from Imagewriter. I have a DVSD PAL video from a commercial 8mm film scanner which "info" assures me is YV12.
I have tried all combinations of interlace=true, assumefield/framebased, matrix = x y and z etc and have been completely unsuccessful.

ConvertToRGB24(interlaced=true) at the end of the script.

and have been completely unsuccessful.

Unsuccessful meaning it didn't work at all, or didn't work as you expected?

Thanks for replies.

I have a simple script
main=(...)
converttorgb (main, interlace=true)
#(or converttorgb24 etc)
info(main) #or return main

in VirtualDub
info tells me it's still YV12
If I put in Imagewriter (jpegs) at the end, I get error "DevIL requires RGB input"

Probably something extremely simple, but baffles me.

main=(...)
converttorgb (main, interlace=true)
#(or converttorgb24 etc)
info(main) #or return main
Should be:
main = converttorgb (main, interlaced=true)

Otherwise, the result of the conversion is not used and is thrown away.

converttorgb (main, interlace=true)
#(or converttorgb24 etc)
info(main) #or return main


As Gavino says or:


main=(...)
converttorgb(main, interlace=true)
last.info()

Unbelievable.

Told you it was something simple.

Thanks a lot guys
