#Personal – A HDMI Audio Video Capture Card for less $20 will help you with screen sharing, #raspberrypi, phones and more !

Buy Me A Coffee


Today I want to share a small device that literally change the way I do demos, check screens and other scenarios. A simple HDMI Audio Video Capture Card for less than 20$.

HDMI Audio Video Capture Card: High Definition 1080p 30fps – HDMI to USB2.0 – Video Recording via DSLR & Camcorder to Live Streaming | Gaming | Teaching | Live Broadcasting | Video Conference

Somehow in my mind these devices were supposed to be super expensive (and I know they are!). Last year, I decided to try a cheap one and it was a great surprise.

How this works? You connect a HDMI input into the USB device and you have a new camera available. Then you can use any camera app to check or share this screen. The following image shows the boot of a raspberry pi with the camera recorded as a video.

This is not remote desktop, so you won’t have keyboard and mouse remote control. I’ll blog on hyot to do this in other post.

The main idea of connection is this one

I’m my day to day, I use this to

  • Share screen of some devices like raspberry pi.
  • Share screen of other laptops. I know, remote desktop is an option, however this is SO MUCH FASTER!
  • Share screen of smartphones, when they have the feature of USB to HDMI
  • Record demos from smartphones to have backup videos, just in case!
  • And more !

Final sample, this how a smartphone screen looks

And finally, my cheap device

Happy coding!

#WINDOWS10 – HowTo: Use #Xbox app to perform #ScreenRecording


In my yesterday’s post, I wrote about the set of tools I use to make some screen capture: SnagIt and Camtasia. Mostly Camtasia for screen recording, because I can encode the final video in animated GIFs format which is very useful for my blog. Is a pity that we don’t have a tool in Windows to perform this, however we can reuse some other tools with this feature.

In example, let’s do this with the Xbox app in Windows 10

– Launch the Xbox app

– Switch to the app we want to record

– Press WIN + G to open the Game Bar. First time, we’ll see a confirmation message, to validate if this app is a game.

– Go for YES. And we’ll see the Game Bar. Now we have the option “Start Recording”, also we can start the recording with WIN + ALT + R

– Recording mode is ON

The following image is the previous set of steps to make a screen recording of the Calculator in Windows 10

And we have some customization Features available, like change the combinations of action keys, change the recorded videos folder, etc. All the settings can be changed from [Settings // Game DVR]
