I guess that means that the audio codec used for the dv file can't be used in a .wav container. I thought DV always used LPCM, but perhaps that's my mistake. You can just drop the -c:a copy; that will convert it to linear PCM (probably at smaller bitdepth, but that's fine, will have to be downsampled anyway). If that also fails, maybe run this: ffmpeg -i <source> -t 60 -c copy fragment.dv which creates a one-minute sample in "fragment.dv", and then put that oneline somewhere, so I can see what's happening. -- To the thief who stole my anti-depressants: I hope you're happy -- seen somewhere on the Internet on a photo of a billboard
