Summary of the bug:
DV25 supports audio at 48, 44.1 and 32 kHz, but when I use 44100 or 32000
I get an error.
How to reproduce:
{{{
ffmpeg -y -f lavfi -i mandelbrot=r=30000/1001:s=720x480 -f lavfi -i sine
-map 0 -map 1 -pix_fmt yuv411p -c:v dvvideo -aspect 4/3 -t 3 -ac 2 -ar

[dv @ 0x7fea9a802400] Can't initialize DV format!
Make sure that you supply exactly two streams:
video: 25fps or 29.97fps, audio: 2ch/48|44|32kHz/PCM
(50Mbps allows an optional second audio stream)
Could not write header for output file #0 (incorrect codec parameters ?):
Operation not permitted
Error initializing output stream 0:1 --
Conversion failed!

I've reviewed dvenc.c but am uncertain if I'm doing something wrong. If I
switch from -ar 32000 to -ar 48000, then it works as expected.
