I'm trying to convert from flac to AAC (with libfdk-aac). But when I do it
appears to complain about the cover art. This is a sample. The source is
created with Exact Audio Copy if it matters.

Stream #0.1: Audio: libfdk_aac, 0 channels, 200 kb/s
Stream mapping:
Stream #0:1 -> #0:0 (mjpeg (native) -> ? (?))
Stream #0:0 -> #0:1 (flac (native) -> aac (libfdk_aac))
Automatic encoder selection failed for output stream #0:0. Default encoder for
format ipod is probably disabled. Please choose an encoder manually.
So it appears to me that it is finding the cover art as a mjpeg? I can mark
the destination file as a .aac, or I can pass in -vn to disable the video
stream, but those both leave a container with no cover art. I feel like I'm
missing something basic here.
Thanks!_______________________________________________
