Webcam streaming throught VLC with YUY2 compatibility

If you try to stream your webcam throught VLC you probably will see the following issue:

# vlc v4l2:///dev/video0 --sout '#rtp{mux=ts,sdp=rtsp://:8888/live.sdp}' 

 VLC media player 3.0.4 Vetinari (revision 3.0.4-0-gf615db6332)
[000055c7620dd630] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
[00007ff730002fe0] main mux error: cannot add this stream
[00007ff730001180] stream_out_rtp stream out error: cannot add this stream to the muxer
[00007ff73000ff60] main decoder error: cannot create packetizer output (YUY2)
[00007ff73000ff60] main decoder error: buffer deadlock prevented

 To fix it, you must enable the transcoding and run the following command:

cvlc -vvv v4l2:///dev/video0:chroma=mp2v --v4l2-width 1280 --v4l2-height 720 --sout '#transcode{vcodec=mp2v,acodec=mpga,fps=30}:rtp{mux=ts,sdp=rtsp://:8888/live.sdp}'

where chroma enables hardware video decoding. You can edit the resolution, codecs and frame per seconds to enchance the video speed.

To run it, just run:

vlc rtsp://127.0.0.1:8888/live.sdp

Enjoy it!

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work. I can't see notifications from my apps and the arrow and the screw icon to settings access don't work. 2) As I can't access to the notification area, I can't enable Use USB to Transfer Files to access to my phone memory. 3) I can't access to developer mode (I before active it with a lot of taps over Build number). Clicking on developer options just shows developer options are not available to this user. 4) I can't update or install the apps on google play. They freeze on Download pending... message 5) Home and Switch buttons don't work. They light up and vibrate when I tap them but they do nothing. This issue is apparently related to a deconfiguration of user accounts. To fix it, you need re-setup the users. As you can't access to the user manager (you are in guest mode
