Verketten Sie mit ffmpeg mp4-Dateien mit verschiedenen fps und sar

Ich muss sechs mp4-Dateien in eine zusammenführen. Hier sind die Informationen zu den Dateien:

pt1.mp4

Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 854x480 [SAR 1280:1281 DAR 16:9], 997 kb/s, 23.98 fps, 23.98 tbr, 11988 tbn,  Stream #0:1(eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 127 kb/s (default) 

Nachdem Sie die Dokumentation zu ffmpeg gelesen haben, konvertieren Sie die Dateien in ts und dann concat:

ffmpeg -i pt1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts pt1.ts ... ffmpeg -i pt6.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts pt6.ts ffmpeg -i concat:"pt1.ts|pt2.ts|pt3.ts|pt4.ts|pt5.ts|pt6.ts" -c copy -bsf:a aac_adtstoasc output.mp4 

Leider funktioniert die resultierende Datei nicht normal, obwohl die Dateien separat funktionieren.

Hier ist das Protokoll der Verkettung:

Vielleicht liegt dies an einer anderen Framerate, fünf Stück FPS 23,98 und einem 29,97?
