            Component:               |  unspecified

 To reproduce, use this command:
 {{{
 ffmpeg
 -r 15.184325488557473
 -f image2
 -thread_queue_size 64
 -i /frames/%d.webp
 -i videomail_preview.wav
 -y
 -acodec aac
 -strict experimental
 -ar -1
 -ac 1
 -vcodec libx264
 -vf scale=trunc(iw/2)*2:trunc(ih/2)*2
 -crf 16
 -preset fast
 -profile:v baseline
 -pix_fmt yuv420p
 -loglevel warning
 -movflags faststart videomail_good.mp4
 -acodec libvorbis
 -ar -1
 -ac 1
 -vcodec libvpx
 -vf scale=trunc(iw/2)*2:trunc(ih/2)*2
 -crf 8
 -deadline good
 -cpu-used 1
 -pix_fmt yuv420p
 -loglevel warning
 -movflags faststart videomail_good.webm
 }}}

 causes following error

 {{{
 ffmpeg exited with code 1: Output pad "default" with type audio of
 the filter instance "Parsed_anull_0" of anull not connected to any
 destination
     Error opening filters!
 }}}

 and this is my version

 any ideas why this error and what's bad with the command I am using?
