色々事情がありまして，しばらくRTSPを視聴<\/a>せずに来ましたが，また必要にかられて再開<\/a>しました．<\/p>\n\n\n\n

macOSでVLCの本家からdownloadしたVLC media playerは，従来どおり難なく視聴できます．たぶんWindowsでも本家からdownloadすれば使えると思います．<\/p>\n\n\n\n

ところが，Manjaro (AMD64版)では視聴できなくなっていました．Debian同様ソースコードにライセンス上の問題があるとかそういう関係でRTSPの機能を除外してしまったのでしょうか1<\/a><\/sup>筆者にはその辺の事情は関係ないので調べません😅<\/span>．<\/p>\n\n\n\n

ManjaroでRTSPが視聴可能というのは，Raspberry Piでも視聴可能にできるという大きな意義があったのですが，それができないとなると，Raspberry Piでの監視カメラ2<\/a><\/sup>日本の政府やメディアは「防犯カメラ」と呼ばせたいようですが．<\/span>システム構築に大きな支障となってしまいます．<\/p>\n\n\n\n

さてどうするか<\/h3>\n\n\n\n

ManjaroのVLCでRTSPの再生ができないことを他のいくつかの環境からテストしてみます．それで確定となれば新しいdistroを探さなければなりません．<\/p>\n\n\n\n

Slackwareではsbopkgでbuildできること<\/a>が解っています．しかし，slackbuilds.org<\/a>に登録されているスクリプトは，すべてのアーキテクチャでエラー無くbuildできるとは限りません．特に最終ゴールはRaspberry Pi 3なので，AMD64やx86環境はOKでもaarch64環境でbuildができる可能性は低いと考えています．<\/p>\n\n\n\n

それと，依存ファイルの多さです．35もあります．オプショナルなモジュールならば無くてもVLCのbuildスクリプトがその機能を除外して先に進んでくれるようですが，必須のライブラリーがbuildできないとそこでアウトです．一番成功の可能性が高いAMD64でのbuildも躊躇してしまいます．<\/p>\n","protected":false},"excerpt":{"rendered":"
