Tengo un audio(REC00006.wav) de 6 segundos de duración. Tengo un video (SUNP.avi) de 17 segundos de duración.
Necesito fusionar estos dos archivos, pero el audio debe provenir del segundo 11 al 17 del video.
Incluyo el código aquí. Fusionarse es el éxito. Pero el audio proviene del inicio del video.
ffmpeg -y -i SUNP.AVI -itsoffset 00:00:11 -i REC00006.wav -acodec copy -vcodec copy -map 0:0 -map 1:0 C:\Users\admin\Desktop\HH3C01650\SUNP_REC00006.avi
Aquí está la salida de la consola.

Utilizar esta:
ffmpeg -y -i F:\DCIM\100MEDIA\SUNP.AVI -itsoffset 00:00:11 -i F:\RECORD\REC00006.wav -acodec copy -vcodec copy -map 0:0 -map 1:0 C:\Users\admin\Desktop\HH3C01650\SUNP_REC00006.avi
Solo necesita -yuna vez al principio para sobrescribir el archivo existente con el mismo nombre de salida. El itsoffsetparámetro debe estar en HH:MM:SSformato o HH:MM:SS.DECIMALformato.
