[FFmpeg-user] ffserver audio livestream "Could not open output feed file '/tmp/inputAudio.ffm'"

[Matt Flax]

Hi there,

Need a little help please.
When I run :
ffserver -f /etc/ffserver.conf

I get :
Could not open output feed file '/tmp/inputAudio.ffm'

No problem executing echo to a file in /tmp ... so it doesn't appear to 
be a file system problem.
/tmp is mounted with the following options :
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime)

I am using the wav format :
# ffserver -formats
File formats:
  D. = Demuxing supported
  .E = Muxing supported
  --
   E ffm
  DE wav

My ffserver.conf is :
