J'utilise ffmpeg dans Python pour automatiser certaines compositions vidéo. Pour ce faire, j'utilise le module de sous-processus de Python et exécute une commande ffmpeg avec une entrée pipe. Cela me permet de diffuser image par image la composition vidéo de mon tableau d'images brutes (matrices numpy) dans ffmpeg. Dans l'exemple suivant, j'ai réduit la composition vidéo à une vidéo simple d'une durée de 12 secondes. La commande ffmpeg produit est la suivante:Utilisation de ffmpeg pour la diffusion de la composition vidéo à partir de Python: pourquoi le son est coupé uniquement lors de la diffusion dans un fichier mp4?
ffmpeg -i stream_audio.mp3 -re -f rawvideo -vcodec rawvideo -s 1280x720 -pix_fmt rgb24 -r 25 -i - -map 0:a -map 1:v -y -strict -2 -f mp4 -pix_fmt yuv420p out.mp4
Le fichier stream_audio.mp3 est un fichier MP3 ainsi formé correspondant à la sortie audio du fichier de sortie mp4. Cependant, le son dans le fichier de sortie out.mp4 est coupé 3 secondes avant la fin.
Si j'essaie de sortir un autre format (par exemple avi), je n'observe pas ce problème. La commande suivante produit un fichier avi bien formé.
ffmpeg -i ./stream_audio.mp3 -re -f rawvideo -vcodec rawvideo -s 1280x720 -pix_fmt rgb24 -r 25 -i - -map 0:a -map 1:v -y -b 4096k -f avi -pix_fmt yuv420p out.avi
J'ai essayé de reproduire le bug avec la plus simple commande ffmpeg sans passer par Python, mais n'a pas succeed.The plus proche que je l'ai fait est le suivant:
Création d'un fichier vidéo brut avec les spécifications correctes
ffmpeg -i samplevideo.mp4 -f rawvideo -vcodec rawvideo -acodec none -s 1280x720 -pix_fmt rgb24 -r 25 samplevideo.raw
streaming fichier vidéo brut dans la commande ffmpeg
cat samplevideo.raw | ffmpeg -i /tmp/stream_audio.mp3 -re -f rawvideo -vcodec rawvideo -s 1280x720 -pix_fmt rgb24 -r 25 -i - -map 0:a -map 1:v
-y -strict -2 -f mp4 -pix_fmt yuv420p -ss 00:00:00 -t 00:00:12 out.mp4

Le samplevideo.mp4 de fichier se trouve ici: sample videos, le fichier stream_audio.mp3 est une simple extraction de l'audio piste du fichier samplevideo.mp4:
ffmpeg -i samplevideo.mp4 stream_audio.mp3
Merci pour votre aide.
