Ich füge zwei Videos mit ffmpeg in Android zusammen, aber das Zusammenführen dauert 45 Sekunden. Unten ist mein Befehl
complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-strict", "experimental", "-filter_complex",
"[0:v]scale=480x640,setsar=1:1[v0];[1:v]scale=480x640,setsar=1:1[v1];[v0][0:a][v1][1:a] concat=n=2:v=1:a=1",
"-ab", "48000", "-ac", "2", "-ar", "22050", "-s", "480x640", "-vcodec", "libx264","-crf","27","-q","4","-preset", "ultrafast", rootPath + "/output.mp4"};
Ich habe die ffmpeg-Bibliothek in mein Projekt aufgenommen, indem ich die folgende Zeile in Gradle-
compile 'com.writingminds:FFmpegAndroid:0.3.2'
Unten ist mein Protokoll

Codec AVOption preset (Set the encoding preset (cf. x264 --fullhelp)) specified for output file #0 (/storage/emulated/0/output.mp4) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.

Wie kann ich das schneller machen?
Du kannst es höchstwahrscheinlich nicht. 45 Sekunden sind KEINE lange Zeit, um ein Video auf Android zu codieren. Sie fügen nicht einfach eine Datei an das Ende einer anderen ein, Sie codieren ein neues Video, das den Inhalt beider Videos enthält, die nacheinander abgespielt werden. Dazu muss das gesamte Video transkodiert werden, um ein neues zu erstellen, und das braucht Zeit. 45 Sekunden sind eigentlich ziemlich schnell, abhängig von der Länge der beiden Clips, die Sie kombinieren.
Wenn die beiden Clips ähnliche Codierungseinstellungen haben, ist es möglicherweise möglich, ein Containerformat zu verwenden, das das Verketten mehrerer Dateien hintereinander unterstützt, aber es würde dann eher wie eine Wiedergabeliste als wie ein kontinuierliches Video abgespielt.
