MJPG-streamer 参考サイトのとおり、インストールすると動く。第8回: MJPG-streamerのインストール Raspberry Pi でWebカメラ (4) M-JPEG streamerをつかったストリーミング配信 Raspberry Piでwebカメラの映像を配信する方法(MJPG-streamer編)
枝葉は異なるが、参考サイトは全て同じ手順で実施しているので、以下で動く。
$ cd ~
$ mkdir mjpg-streamer
$ cd mjpg-streamer
その後、以下のコマンドを実行してください。
svn ではなく git clone https://github.com/jacksonliam/mjpg-streamer.git だな。sourceforgは終了したので、下のsvnでははねられた。2022.6.24
sudo apt-get install cmake libjpeg9-devsudo apt-get install gcc g++ も最新のRasPiOSならいらないはず。これは飛ばして次に。git clone https://github.com/jacksonliam/mjpg-streamer.git cd mjpg-streamer-experimental
make
sudo make install
$ sudo apt-get install subversion libjpeg-dev imagemagick
$ svn co https://mjpg-streamer.svn.sourceforge.net/svnroot/mjpg-streamer mjpg-streamer
$ cd mjpg-streamer/mjpg-streamer
$ make
$ sudo install
start_server.sh
#!/bin/sh
PORT = "8080" #ポート番号
ID = "xxxx" #IDは好きなもの
PW = "xxxxxxxx" #パスワード
SIZE = "640x480" #画面サイズ
FRAMERATE = "20" #フレームレート
export LD_LIBRARY_PATH = /usr/local/lib
./mjpg_streamer \
-i "input_uvc.so -f $FRAMERATE -r $SIZE -d /dev/video0 -y -n" \
-o "output_http.so -w /usr/local/www -p $PORT -c $ID : $PW "
$ sh start_server.shを実行すると、RasPiのコンソールは以下のような表示が表れます。
$ sh start_server.sh
MJPG Streamer Version: svn rev: 3:172

Ras Pi 4では次のものがエラーなしだった
