Raspberry Pi 3 (Raspberry Pi OS Bullseye)でRTSPを見るのはffplayが楽だと記事を書いた<\/a>翌日に，Raspberry Pi OS Bookwormがリリースされました．Debian Bookwormは随分前にリリースされ，Raspberry Pi OS Bookwormも近々リリースされると聞いてはいましたが，翌日とはなんというめぐり合わせでしょう．<\/p>\n\n\n\n

それで，早速Raspberry Pi 3 Model Bと同Model B+にインストールしてあるRaspberry Pi OSをBullseyeからBookwormにupgradeしてみましたが，結構手間と時間がかかるうえ，ちょっとしたトラブルにも巻き込まれてしまいました．<\/p>\n\n\n\n

もし，Raspberry PiをRTSPを見るなど単機能のみに使用するのでしたら，クリーンインストールのほうがずっと楽だし時間もかかかりませんし，トラブルも起きにくいです．<\/p>\n\n\n\n

Upgradeしてだめならクリーンインストールという方が時間を潰すには適していますが😅<\/p>\n\n\n\n

ところで，Raspberry Pi OS Bookwormもデフォルトのインストールでは，swapにファイルを使うdphys-swapfileでした．SDカードをswapに使うのは全くメリットがない1<\/a><\/sup>書き込みが遅いし書き込みを繰り返すと寿命が来る．<\/span>ので，デフォルトでZRAMを採用してほしかったですが，まあたぶん開発元ではいろんな議論があったのでょう．<\/p>\n","protected":false},"excerpt":{"rendered":"
