作者分享如何使用 Python 偵測 AV1 編碼的影片,以便將無法在舊裝置上播放的影片轉換為較舊的編碼格式。文章介紹了兩種方法:利用 `ffprobe` 命令列工具,以及更快速且直接的 `pymediainfo` Python 套件。最終,作者將這些方法整合到一個 pytest 測試中,用以掃描整個影片庫並找出所有 AV1 編碼的 MP4 檔案,確保所有影片都能順暢播放。
+ 這篇文章的實用性很高!我正好有類似的問題,不知道如何批量找出那些不相容的影片。ffprobe 的方法很詳細,不過 pymediainfo 聽起來確實更有效率。
+ 寫測試來解決問題是很棒的做法。作者很細心地解釋了 ffprobe 和 MediaInfo 的指令,以及為什麼 pymediainfo 的方法更快。最後的 pyt

Detecting AV1-encoded videos with Python

I wrote a Python test to find videos that are encoded with AV1, so I can convert them to a codec my iPhone can play.

Für diverseste Formatdetails übrigens sehr hilfreich: Das Linux-GUI-Werkzeug #MediaInfo. Damit wird auch schnell sehr klar, ob man 16- oder 24-Bit vorliegen hat, was dir die wenigsten Player sagen.

VLC behauptet fälschlicherweise bei jedem Format, er hätte es mit 32 Bits pro Sample zu tun. MPV macht unter der Taste "i" immerhin korrekt den Unterschied zwischen "Format: s16" und "s32", was aber in echt dann 24-Bit ist. MediaInfo ist trotzdem klarer.
