Webcam capture device recognized but nothing displayed

Posted: 09 Nov 2017 15:21

Hello,

I would like to stream a webcam (Logitech HD Webcam C270) from VLC, on a Windows 7 computer.

I do the following:
- Media > open capture Device
- Video device name: i choose my webcam Logitech HD Webcam C270
- Play

Then the playing time is running but only the VLC icone is shown on the screen.

Sometimes it works, but I don't manage to know why (only 1 time out of 20).

Here is the message from VLC if it is related:

Code: Select all

logger info: VLC media player - 2.2.6 Umbrella logger info: Copyright © 1996-2017 the VideoLAN team logger info: Warning: if you cannot access the GUI anymore, open a command-line window, go to the directory where you installed VLC and run "vlc -I qt" logger info: using logger. logger error: error opening logfile `vlc-log.txt': Permission denied core error: no suitable interface module core error: interface "logger,none" initialization failed
Thank you for your help,

Please open Tools -> Messages (set Verbosity to 2) before you start the streaming, and then paste the full resulting log here or on Pastebin.com if it's too long.

Sorry, I am clueless about that. Something is blocking in the dshow module, but no idea what.

I solved the issue by just removing the USB extension (~2meters) that I added to the webcam one....
