raspberry pi ヴィデオ関連 /Micro:bit keyestudioで無線操縦

 

-----------ラズパイ----------------------------------------

zero は２になっても２GしかWifi未対応　３a+は5Gも対応している

install時のusキーボード配列は、起動後にraspi-configでjpキーボードに変更できた

　これはブルーバックスと同じだが、ブルーバックスは

　全コマンドを/opt以下にmvしたので、10-02-stream.shを使用！

単純にヴィデオクリップするのならguvcviewがいい パイカメラの場合はv4l2が必要？

USBウェブカメラ（マイク付き）なら録音もできるからベターかも
