使い道のないRaspberry Pi 3 Model B (RPi3) やRaspberry Pi 3 Model B+ (RPi3+)で，RTSPを視聴する方法の結論としては，<\/p>\n\n\n\n

\n

ffplay (FFMPEG)で見る<\/p>\n<\/blockquote>\n\n\n\n

で最終決定しました1<\/a><\/sup>その後，Raspberry Pi OS配布のVLCでRTSP視聴ができるように復旧<\/a>しました．<\/span>．唯一懸念されていた時間遅れの蓄積は，その後半日ほど連続運転したところ，不思議と解消されました2<\/a><\/sup>たぶん，下記のスクリプトのように，コンソールにlogを出さないようにしたためかもしれません．それでも多少は遅れます．<\/span>．<\/p>\n\n\n\n

FFMPEGが使えるならばRaspberry Pi OSでも行けるはずですが，いまさら面倒なので3<\/a><\/sup>と言いつつ後日試しました．ffplayだけのためにインストールするなら，Raspberry Pi OSが一番楽で，起動も早い<\/a>のでお勧めです．<\/span>，RPi3ではManjaro ARM xfce, RPi3+ではManjaro ARM KDE Plasmaでこのまま行きます．<\/p>\n\n\n\n

自動起動については，<\/p>\n\n\n\n

というスクリプトを実行可能にして適当な場所に置いて設定からAutostartに指定したら，xfceもKDE Plasmaもうまくいきました．sleep 30については要調整です．フルスクリーンオプション-fs<\/code>はお好みで．<\/p>\n\n\n\n
