Buon pomeriggio, ho trovato ad installare la mia webcam trust su Ubuntu 19.10, ma sebbene rilevata dal sistema, non viene vista da programmi quali skype o cheese. |
Ok grazie mille per tutto. Ho provato a cambiare porta USB ma la webcam trust non si appende proprio. a questo punto ho riesumato una webcam della play station la eye toy che prima non funzionava mentre ora con guvcview funziona bene, mentre con Skype viene riconosciuta ma rimane immagine nera. |

da lsmod | grep gspca ho questo riscontro: sergio@sergio-desktop:~$ lsmod | grep gspca sergio@sergio-desktop:~$ Come dovrei fare per vedere "mplayer tv://dev/video0 " ?

Ciao ho installato mplayer, ma quando lancio mplayer da terminale ho questa risposta: sergio@sergio-desktop:~$ mplayer tv://dev/video0 Creating config file: /home/sergio/.mplayer/config MPlayer 1.3.0 (Debian), built with gcc-9 (C) 2000-2016 MPlayer Team do_connect: could not connect to socket connect: No such file or directory Failed to open LIRC support.

Exiting... (End of file)
lo vedi anche da: ls -l /dev/video*
dopo non trovi il video0 ? dmesg | grep video |
Ho caricato manualmente sudo modprobe gspca_pac207 e poi eseguito dmesg | grep video con questo risultato: sergio@sergio-desktop:~$ sudo modprobe gspca_pac207 [sudo] password di sergio: sergio@sergio-desktop:~$ dmesg | grep video [ 1094.396831] videodev: Linux video capture interface: v2.00 |

Con il comando ls -l /dev/video* il risultato è sempre di errore: sergio@sergio-desktop:~$ dmesg | grep video [ 729.711919] videodev: Linux video capture interface: v2.00 sergio@sergio-desktop:~$ ls -l /dev/video ls: impossibile accedere a '/dev/video': File o directory non esistente sergio@sergio-desktop:~$ ls -l /dev/video ls: impossibile accedere a '/dev/video': File o directory non esistente |
