Help, cannot connect to my webcam (message : Could not RenderStream to connect pins, I/O error)
Hi, trying to use ffmpeg to capture screen, I connected my old un-used web cam (Microsoft LifeCam VX-6000 to my windows 7 notebook. according to the directions on the web, in the ffmpeg prompt, I entered
ffmpeg -list_devices true -f dshow -i dummy
to see the web cam is recognized by ffmpeg. (It read "Microsoft LifeCam VX-6000") So I endtered to record the screen,
ffmpeg -f dshow -i video="Microsoft LifeCam VX-6000" test.mp4
but it gave me error below : [dshow @ 000000000046a9a0] Could not RenderStream to connect pins video=Microsoft LifeCam VX-6000: I/O error I looked it up on the web and tried reconnecting the web cam, and installing K-Lite codec pack for no avail. What could be the problem? Any suggestion will be deeply appreciated. Thanks! Chan

to see the web cam is recognized by ffmpeg. (It read "Microsoft LifeCam VX-6000")
So I endtered to record the screen,
ffmpeg -f dshow -i video="Microsoft LifeCam VX-6000" test.mp4
Please provide your failing command line together with the complete, uncut console output, use copy-paste, do not attach screenshots.
