関東ではマックといいますが，フランスではマクドというらしいです．<\/p>\n\n\n\n
VLC macOS版の3.0.20 (Intel 64bit版)も，うちのカメラのRTSPを表示してくれなくなりました．ずっとこのバージョンのままのような気もするので，カメラ側の仕様が変更になってコンパチビリティーが失われたのかもしれません（少し前にカメラのfirmwareのupdateがありました）．<\/p>\n\n\n\n
Raspberry Pi OS版のVLCも含めて症状は同じで，カメラに接続したその時の画像が静止したままです．システムもVLCも生きていて，<\/p>\n\n\n\n
killall vlc<\/code><\/pre>\n\n\n\nで止められます．<\/p>\n\n\n\n
それでマクドミニの方でもffplayを試してみようかと思ったら，当然ですがX用しかなく，まずXQuartzをupdateしてからMacPortsでFFMPEGをインストールしました．<\/p>\n\n\n\n
その結果大きな問題なく動きました．<\/p>\n\n\n\n
正常に動いた場合のVLCと比較して，Raspberry Pi OS版と同様に小さいブロックノイズが時々出ます1<\/a><\/sup>VLCでは出ません．<\/span>．また時間遅れがかなりあります2<\/a><\/sup>遅れが蓄積していくかは検証してません．<\/span>．<\/p>\n","protected":false},"excerpt":{"rendered":"\u95a2\u6771\u3067\u306f\u30de\u30c3\u30af\u3068\u3044\u3044\u307e\u3059\u304c\uff0c\u30d5\u30e9\u30f3\u30b9\u3067\u306f\u30de\u30af\u30c9\u3068\u3044\u3046\u3089\u3057\u3044\u3067\u3059\uff0e VLC macOS\u7248\u306e3.0.20 (Intel 64bit\u7248)\u3082\uff0c\u3046\u3061\u306e\u30ab\u30e1\u30e9\u306eRTSP\u3092\u8868\u793a\u3057\u3066\u304f\u308c\u306a\u304f\u306a\u308a\u307e\u3057\u305f\uff0e\u305a\u3063\u3068\u3053\u306e\u30d0\u30fc\u30b8\u30e7\u30f3\u306e\u307e\u307e\u306e\u3088\u3046\u306a\u6c17\u3082\u3059\u308b\u306e\u3067\uff0c\u30ab\u30e1\u30e9\u5074\u306e\u4ed5\u69d8\u304c\u5909\u66f4\u306b\u306a\u3063\u3066\u30b3\u30f3\u30d1\u30c1\u30d3\u30ea\u30c6\u30a3\u30fc\u304c\u5931\u308f\u308c\u305f\u306e\u304b\u3082\u3057\u308c\u307e\u305b\u3093\uff08\u5c11\u3057\u524d\u306b\u30ab\u30e1\u30e9\u306efirmware\u306eupdate\u304c\u3042\u308a\u307e\u3057\u305f\uff09\uff0e Raspberry Pi OS\u7248\u306eVLC\u3082\u542b\u3081\u3066\u75c7\u72b6\u306f\u540c\u3058\u3067\uff0c\u30ab\u30e1\u30e9\u306b\u63a5\u7d9a\u3057\u305f\u305d\u306e\u6642\u306e\u753b\u50cf\u304c\u9759\u6b62\u3057\u305f\u307e\u307e\u3067\u3059\uff0e\u30b7\u30b9\u30c6\u30e0\u3082VLC\u3082\u751f\u304d\u3066\u3044\u3066\uff0c \u3067\u6b62\u3081\u3089\u308c\u307e\u3059\uff0e \u305d\u308c\u3067\u30de\u30af\u30c9\u30df\u30cb\u306e\u65b9\u3067\u3082ffplay\u3092\u8a66\u3057\u3066\u307f\u3088\u3046\u304b\u3068\u601d\u3063\u305f\u3089\uff0c\u5f53\u7136\u3067\u3059\u304cX\u7528\u3057\u304b\u306a\u304f\uff0c\u307e\u305aXQuartz\u3092update\u3057\u3066\u304b\u3089MacPorts\u3067FFMPEG\u3092\u30a4\u30f3\u30b9\u30c8\u30fc\u30eb\u3057\u307e\u3057\u305f\uff0e \u305d\u306e\u7d50\u679c\u5927\u304d\u306a\u554f\u984c\u306a\u304f\u52d5\u304d\u307e\u3057\u305f\uff0e \u6b63\u5e38\u306b\u52d5\u3044\u305f\u5834\u5408\u306eVLC\u3068\u6bd4\u8f03\u3057\u3066\uff0cRaspberry Pi OS\u7248\u3068\u540c\u69d8\u306b\u5c0f\u3055\u3044\u30d6\u30ed\u30c3\u30af\u30ce\u30a4\u30ba\u304c\u6642\u3005\u51fa\u307e\u3059\uff0e\u307e\u305f\u6642\u9593\u9045\u308c\u304c\u304b\u306a\u308a\u3042\u308a\u307e\u3059\uff0e<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_daextam_enable_autolinks":"","footnotes":""},"categories":[22,27,28],"tags":[],"class_list":["post-23902","post","type-post","status-publish","format-standard","hentry","category-macintosh-computer","category-rasapberry-pi","category-security"],"publishpress_future_action":{"enabled":false,"date":"2026-04-18 18:16:51","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/je1sgh.mydns.jp\/je1sghblog\/index.php?rest_route=\/wp\/v2\/posts\/23902","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/je1sgh.mydns.jp\/je1sghblog\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/je1sgh.mydns.jp\/je1sghblog\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/je1sgh.mydns.jp\/je1sghblog\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/je1sgh.mydns.jp\/je1sghblog\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=23902"}],"version-history":[{"count":0,"href":"https:\/\/je1sgh.mydns.jp\/je1sghblog\/index.php?rest_route=\/wp\/v2\/posts\/23902\/revisions"}],"wp:attachment":[{"href":"https:\/\/je1sgh.mydns.jp\/je1sghblog\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=23902"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/je1sgh.mydns.jp\/je1sghblog\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=23902"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/je1sgh.mydns.jp\/je1sghblog\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=23902"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
