Note that I used the device name I got from earlier query. So, we need to get more information about the device by using this command:įfmpeg -f dshow -list_options true -i video="HP Truevision HD" We can control by give the proper parameters. Sometimes the frames may be dropped because ffmpeg wants to keep up the the real time input.
We may also need to give our devices certain parameters such as size or frame rate etc. "Stereo Mix (Realtek High Definition Audio)" "Microphone (Realtek High Definition Audio)"

I also use a high-quality Bluetooth earbud for audio and microphone, which is far better than the echo of using the built-in speakers and mics (though the Spectre's mics are far better than most laptops).įinally, the conf software you use can be important. I usually move a lamp in the hotel room and use the wall behind my laptop as a giant reflector to illuminate me without hard shadows. That may be why it looks better at Best Buy. You can make the built-in camera look better by setting up decent lighting and ensuring you are not backlit. Carrying an external camera is annoying but I don't mind too much because when I'm using the camera it's on something important enough that I'm at a fixed location and I bring the USB camera in my suitcase instead of my backpack (along with the x360 power supply). The Brio is the best widely available USB webcam followed by the Logitech 920, which is a bit smaller. Instead, when I care about the quality, I bring a Logitech Brio and plug it in. I still bought the Spectre despite the typically weak camera because there aren't many laptops with substantially better ones at the moment and those tend to be higher end specialized rigs that aren't thin and light nor convertible 2 in 1s. I care a lot about it because I video conf all the time.
Most mainstream reviews don't focus much on cameras in laptops like they do for phones, though the good nerd sites do. I assume this is because their marketing data says most IT depts don't have cam quality as a requirement. The manufacturers seem to not invest much in the hardware. The issue is more the hardware than the software. In general, laptop webcams suck because they have to be thin and fit in the bezel with a small hole.
