use this demo by larrylart https://github.com/larrylart/codrive/tree/master/hw_sampling/vim3_npu

you can change the source to a rtsp stream and recompile

[AKBAAR]

I dont understand, why would i go to some outside sources while there is a an official wiki for this device, isnt that what i paid for ?

if I cant use the official Khadas wiki this renders the wiki useless to everyone ? or is it useless to me only ? i dont understand, i am sorry but this dont make any sense and i refuse to use outside sources than the wiki provided by Khadas itself… please help with the official wiki from Khadas. thank you for your reply regardless…

[AKBAAR]

thanks for the rtsp camera solution ,

[Archangel1235]

you can do the same for the demo given by khadas

just change the source to rtsp stream from your ip camera

[AKBAAR]

i still get error even with the one u gave me

is there something wrong?

[Frank]

@AKBAAR The Docs was use for PC . Not use in VIM3 . You need to convert with PC .

[Frank]

@AKBAAR If you want to try with demo . You should try with this .
