H.265／HEVCコーデック対応Hack

さて、今回は裏技Hackを紹介します。
お持ちのスマートフォンが比較的新しい方は、撮影された動画のコーデックがH.265／HEVC（High Efficiency Video Coding）の方も多いのではないかと思います。実は昨年8月までは追加アプリのCodexPackを導入する事で各種コーデックに対応していたのですが、2019年9月2日のCodexPackのアップデートからH.265／HEVCへの対応が削除されてしまいました。結果としてPhoto StationやQuMagieでサムネイルも消え、動画が再生できない状態となりました。他にもVideo Station等の動画再生アプリでもH.265でエンコードされた動画が見えなくなり困っておりました。

今回はその解決方法として、H.265／HEVCの対応を復活させたいと思います。これにより、最新のffmpegに対応しているコーデックにすべて対応しますので、Googleが推している最新のAV1コーデック等も再生可能となります。また、このコーデック対応はPlex ServerやTwonky Media等の他のマルチメディアアプリにも効力がありますので、H.265／HEVCファイルが再生できずに困っている方はお試しいただく価値があるかと思います。
ただし、公式に案内されている内容ではないので、あくまでも自己責任にて実施してください。

CodexPackをインストール

まずはAppCenterからCodexPackをインストールします。（2020/2/14時点で、x86/x64版の最新は4.7.0.2です。）

余談ですが、昨年9月にアップデート内容を確認せずに、このCodexPackをアップデートしたときは焦りました。古いVersionのqpkgファイルも保管していなかったので、元に戻すこともできませんでした。QTSを含め、アップデートする際には念のため必要なアップデートなのかを事前に確認することをお勧めします。

ffmpegをインストール

次に、ffmpegをインストールします。こちらは、先日の記事でご紹介しましたQNAPCLUBのレポジトリから導入するのが簡単ですが、QNAPCLUBから直接ダウンロードしてファイルからアプリをインストールしても結構です。

ffmpegをCodexPackにリンクする

さて、準備は整いましたので、SSH等のコンソールから対象のNASにログインして、以下の手順を実行します。ディレクトリの「CACHEDEV1_DATA」という部分は環境によって異なるので、ご自身の環境を確認して適宜置き換えてください。
※繰り返しますが、こちらの作業は自己責任でお願いいたします。

// CodexPackのオリジナルffmpegをバックアップ
# mv /share/CACHEDEV1_DATA/.qpkg/CodexPack/opt/cdx/bin/ffmpeg /share/CACHEDEV1_DATA/.qpkg/CodexPack/opt/cdx/bin/ffmpeg.bak
// QNAPCLUBのffmpegからCodexPackのffmpegにシンボリックリンクを張る
# ln -s /share/CACHEDEV1_DATA/.qpkg/ffmpeg/ffmpeg /share/CACHEDEV1_DATA/.qpkg/CodexPack/opt/cdx/bin/ffmpeg

以上です。これ以降にデコードする場合は新しいffmpegが使用されます。ただし、既にindexされているファイルはサムネイルも作成されないので、明示的にサムネイルの再作成をする必要があります。
このHackはリブートしても有効ですが、CodexPackがアップデートされた際には再度この作業をやる必要があるかと思います。
また、上記内容を元に戻すには、以下のコマンドを入力してください。

// ffmpegのシンボリックリンクを削除
# rm /share/CACHEDEV1_DATA/.qpkg/CodexPack/opt/cdx/bin/ffmpeg
// オリジナルのffmpegを戻す
# mv /share/CACHEDEV1_DATA/.qpkg/CodexPack/opt/cdx/bin/ffmpeg.bak /share/CACHEDEV1_DATA/.qpkg/CodexPack/opt/cdx/bin/ffmpeg

H.265／HEVCが再生できないのは、マルチメディア用途としては非常に厳しいです。理由は明確にされていませんが、ライセンスの関係で対応を外されたのですかね。いつかまた、正式に対応をするようになってくれると嬉しいのですが。
