My Nexus 5 was working fine with my Windows 7 desktop, but when i plugged in a Nexus 5X (running Android 6.x) it was not detected at all (in Windows Explorer or adb). Installing drivers did not help, and the phone was detected fine on another Windows 7 computer. Here’s what fixed it – go into Device Manager and see if you have a ‘Portable Devices’ node. If you don’t, check to see if you have a ‘Android Device’ node. If so, try right clicking the child node and choosing ‘Update Driver Software’.
For me, it found some random USB compatible device or something, and then the ‘Portable Devices’ node suddenly appeared, and all was good! Maybe it will work for you!
$480 for Camstasia? I think not. CamStudio? Buggy as hell. Luckily, we have an excellent FREE cross-platform tool that let’s us easily create a video-recording of your desktop including audio: FFMpeg.
If you are running Windows, download the x64 here.
Extract the downloaded archive and open a command prompt in the bin folder.
To check your version:
ffmpeg version N-79630-g9ac154d Copyright (c) 2000-2016 the FFmpeg developers
To show available input devices for audio:
ffmpeg -list_devices true -f dshow -i dummy
DirectShow audio devices
“Microphone (5- Webcam C170)”
This is the magic string you’ll need to specify in the next, awesome command.
ffmpeg -y -f dshow -i audio="Microphone (5- Webcam C170)" -f gdigrab -video_size 1920x1080 -i desktop -vcodec h264 my-screen-with-audio.mkv
This will record your screen at full-hd encoded using h264 and including audio sourced from your microphone. When you want to stop the recording, press Ctrl+C in command prompt and your video file will be ready, too easy!
If you want to record the screen only (no audio), use:
ffmpeg -f gdigrab -offset_x 0 -offset_y 0 -video_size 1920x1080 -i desktop -vcodec h264 my-screen-only.mkv
Thank you FFMpeg developers!
Using VLC, we can have a video begin playback at a specific screen location and window size. I found this useful when creating a screen recording of some software where I wanted to have a video overlay playing in the corner of the screen at the same time. Here’s the command line I used (for VLC 2.0.8 on Windows 8.1):
vlc.exe –no-video-deco –no-embedded-video –video-x=1320 –video-y=700 –width=600 –video-on-top –qt-system-tray –qt-start-minimized my-video.mp4 vlc://quit
- The vlc://quit is a special playlist entry that causes VLC to quit after playback of the preceeding video.
- Adjust video-x and video-y to set screen position, and set width or height to set window size.
- The no-video-deco and video-on-top will remove the window chrome, and ensure the video is always on top.
