Concat vidéos après l'application de filtres

Je souhaite concaté quelques vidéos de ma caméra de téléphone:

ffmpeg -f concat -i /storage/emulated/0/tmp.sc -codec copy -threads 3 -strict -2 -y /storage/emulated/0/final.mp4

Fondamentalement, cela fonctionne bien.

Mais je voudrais également traiter chaque vidéo avant de concat:

 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

Il fonctionne également comme il se doit. Cependant, lorsque j'essaie de concatter les vidéos traitées – la vidéo finale est toujours cassée et parfois j'avance une erreur non-monotonous DTS in output stream .

Tmp.sc:

 file '/storage/emulated/0/processed0.mp4' file '/storage/emulated/0/processed1.mp4'

MISE À JOUR: donc je suppose que le problème concerne le filtrage – après l'avoir utilisé, les vidéos de sortie ne sont plus uniformes et ne peuvent pas être concédées correctement. J'ai mis à jour les journaux.

UPDATE2: sortie complète et commandes réelles

UPDATE3: voici des exemples de vidéos:

Original1: https://drive.google.com/file/d/0Bzb8d9xvN0SjWVUxT0Z4SzRmd1U/view?usp=sharing
Original2: https://drive.google.com/file/d/0Bzb8d9xvN0SjUkZlLUJjeHRMeDg/view?usp=sharing

Concat filtre

Puisque vous filtrez de toute façon, utilisez le filtre concat et faites tout en une seule commande:

 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

Pour que ce filtre fonctionne correctement, tous les segments doivent commencer à l'horodatage 0 (par exemple avec les setpts comme indiqué ci-dessus).
Tous les flux correspondants doivent avoir les mêmes paramètres dans tous les segments; Le système de filtrage sélectionnera automatiquement un format de pixel commun pour les flux vidéo, et un format d'échantillon commun, une fréquence d'échantillonnage et une disposition de canal pour les flux audio. D'autres paramètres, tels que la taille de l'image, doivent être convertis explicitement par l'utilisateur.

Concat demuxer

Si vous souhaitez simplement concaténer sans recodifier, vous pouvez essayer le demigner concat .

Créez un fichier texte répertoriant vos entrées:

 file '/path/to/input0' file '/path/to/input1' file '/path/to/input2'

Concaténer avec ffmpeg :

 ffmpeg -f concat -i input.txt -c copy output.mp4

Tous les fichiers doivent avoir les mêmes flux (même codecs, même base de temps, etc.).
