Re: [Linphone-developers] 064e:a101 Suyin Corp. Cam in Acer Notebook

Hi Conrad,

You are not the only one having this problem.
What is the driver name of the camera ?
It is perhaps a bug in the driver, but it can surely be workarounded since 
ffmpeg succeed to talk with that driver.
I need to dig into the driver source to understand what that protocol error 
means, that's why I'd like to know the driver name.
Thanks

Simon
