ffmpeg - アンドロイドでフィルタを使用する

Question

私はffmpegで自分のAndroidプロジェクトでムービーフィルタを使用しようとしています。私はガーディアンプロジェクトのフォークを使用します：Cheers-dev

最近のバージョンのffmpeg（〜15日の古いatm）を使用しています。フィルターを有効にするには、--enable-filter=movieオプションを追加しました。

私はアンドロイドのプロジェクトで、このコマンドラインを使用します。

ffmpeg -i input.mp4 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" -strict -2 outputvideo.mp4 

それは完璧のDebian Wheezyに上の私のデスクトップバージョンで動作します。しかし、それは私のAndroid上で動作させることは不可能です。その他のコマンドはすべて動作します。

エラーが発生した場合のエラーは、No such filter: 'movie'です。

私も多少異なるエラーとオプション-filter_complexでテスト：

$ ffmpeg -y -loglevel debug -i /storage/sdcard0/test/hsgjr_export.mp4 -i /storage/sdcard0/test/watermark.png -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:main_h-overlay_h-10[out]" -map [out] -map 0:a -codec:a copy /storage/sdcard0/test/hsgjr_watermark.mp4

出力は、前のものよりも優れているが、私は、私は何かが欠けていると思います。

解決策：filter_complex引数から引用符を削除しました。

$ ffmpeg -y -i /storage/sdcard0/test/hsgjr_export.mp4 -i /storage/sdcard0/test/watermark.png -filter_complex [0:v][1:v]overlay=main_w-overlay_w-10:main_h-overlay_h-10[out] -map [out] -map 0:a -codec:a copy /storage/sdcard0/test/hsgjr_watermark.mp4 

Answer 1

は私の問題を解決するために、私はfilter_complex引数を二重引用符を削除：ここ

は作業コマンドです。

$ ffmpeg -y -i /storage/sdcard0/test/hsgjr_export.mp4 -i /storage/sdcard0/test/watermark.png -filter_complex [0:v][1:v]overlay=main_w-overlay_w-10:main_h-overlay_h-10[out] -map [out] -map 0:a -codec:a copy /storage/sdcard0/test/hsgjr_watermark.mp4
