Yeah, it looks like you don't have write permission for the destination folder.

Oh, you're trying to convert FLAC to AIFF. Huh. I'll look at the code.

Thank you ver much.I also fail to convert different formats of 24bit audios (such as wav,alac,aiff and so on) to aiff in ffmpeg.

Yeah, it looks like you don't have write permission for the destination folder.

but it would be successfully converting if the output audio was 16bit

Hi,

Perhaps an endianness-related problem.
Try pcm_s24be instead of pcm_s24le.
