BisonCam NB Pro not working correctly in VMware Xubuntu 16.04
29 août 2016, par bot1131357I am trying to access my webcam (BisonCam, NB Pro) on a VMWare Xubuntu 16.04 virtual machine using ffmpeg, but it’s not working. Here’s what I did :

Could not write header for output file #0 (incorrect codec parameters ?): Immediate exit requested
Exiting normally, received signal 2.At this point I figured that somehow ffmpeg isn’t able to read the frames from the webcam. Just to double-check, I tried running cheese to see if the issue is not exclusive to ffmpeg, and I was right. Here is a screenshot.
Can someone help me with this ?
