Ich möchte ein paar Videos von meiner Handykamera zusammenfügen:
ffmpeg -f concat -i /storage/emulated/0/tmp.sc -codec copy -threads 3 -strict -2 -y /storage/emulated/0/final.mp4
Grundsätzlich funktioniert es gut.
Ich möchte aber auch jedes Video vor der Verkettung verarbeiten:
ffmpeg -i /storage/emulated/0/original0.mp4 -filter_complex scale=1137:640, crop=640:640:248:0, transpose=1 -threads 3 -preset ultrafast -strict -2 -y /storage/emulated/0/processed0.mp4
es funktioniert auch wie es soll. Wenn ich jedoch versuche, die verarbeiteten Videos zusammenzufügen, ist das endgültige Video immer beschädigt und manchmal erhalte ich eine Fehlermeldung non-monotonous DTS in output stream.

AKTUALISIEREN:also ich vermute, das Problem liegt beim Filtern – nach dessen Verwendung sind die Ausgabevideos nicht mehr einheitlich und können nicht mehr richtig zusammengefügt werden. Ich habe die Protokolle aktualisiert.
UPDATE2:vollständige Ausgabe und tatsächliche Befehle

Antwort1
Concat-Filter
Da Sie sowieso filtern, verwenden Sie einfach dieConcat-Filterund erledigen Sie alles mit einem Befehl:
ffmpeg -i input0 -i input1 -i input2 -filter_complex \
"[0:v]scale,crop,transpose,setpts=PTS-STARTPTS[v0]; \
[1:v]scale,crop,transpose,setpts=PTS-STARTPTS[v1]; \
[2:v]scale,crop,transpose,setpts=PTS-STARTPTS[v2]; \
[v0][0:a][v1][1:a][v2][2:a]concat=n=3:v=1:a=1[v][a]" \
-map "[v]" -map "[a]" -c:v libx264 -c:a aac -strict experimental output.mp4
Damit dieser Filter ordnungsgemäß funktioniert, müssen alle Segmente beim Zeitstempel 0 beginnen (wie
setptsoben gezeigt).Alle entsprechenden Streams müssen in allen Segmenten die gleichen Parameter aufweisen; das Filtersystem wählt automatisch ein gemeinsames Pixelformat für Videostreams und ein gemeinsames Sampleformat, eine gemeinsame Samplerate und ein gemeinsames Kanallayout für Audiostreams. Andere Einstellungen, wie die Framegröße, müssen vom Benutzer explizit konvertiert werden.
Concat-Demuxer
Wenn Sie nur verketten möchten, ohne neu zu kodieren, können Sie Folgendes versuchen:Concat-Demuxer.
Erstellen Sie eine Textdatei mit Ihren Eingaben:
file '/path/to/input0' file '/path/to/input1' file '/path/to/input2'Verketten mit
ffmpeg:ffmpeg -f concat -i input.txt -c copy output.mp4
Alle Dateien müssen dieselben Streams haben (dieselben Codecs, dieselbe Zeitbasis usw.).
