It is the smallest increase that matches the "Powers of 2 are recommended"
comment above the constant definition and does not cause an error with the
sample files available to me (the one file attached to ticket #3510 and two
files generated by Adobe Premiere Pro CC).
My command line used for testing was:
./ffmpeg -i sample01.mov -f wav -codec:a pcm_s16le -filter_complex \
"[0:a] amerge=inputs=8 [out_a]" -map "[out_a]" -y /tmp/ffmpeg-test01.wav
