Tomando fotos con la webcam

[jvtecheto]

Hola amigos:

Desgraciadamente Javier Lloris, el autor de la clase hace muchisimo tiempo que no se conecta al foro, esperemos se encuentre bien.(Estuvo enfermo)

Saludos.

Jose.

No creo que sea un problema de drivers, porque la web cam funciona por ejemplo perfectamente con Skype.

Me refiero a la compatibilidad de esos drivers con el "protocolo" que utiliza la clase
Acabo de probarlo incluso en un iMac 27" con windows 10 instalado y funciona correctamente

Cristobal, me podrías enviar el ejecutable que construiste para hacer la aquí la prueba?

No Cristobal, no funciono



Voy a intentar con VS y comento.

Antonio,

I test your sample working. and test my old code that working.
Test it before adjust(setup) webcam driver. so I think Win10 OS need to adjust(setup) webcam driver.
Thanks a lot.

Please download this photos.exe and test it in your PC:
