Hi there, I believe that I've discovered a bug in the SVN version of Liquidsoap wherein piped processes in output.icecast.external do not actually get executed. This only manifests itself on FreeBSD. I was able to use the aacplusenc encoder on my Linux box using the following configuration:
def output.icecast.aacplusenc( ~id="output.icecast.aacplusenc", ~start=true, ~restart=true, ~restart_delay=3, ~host="localhost", ~port=8000, ~user="source", ~password="hackme", ~genre="Misc", ~url="http://savonet.sf.net/";, ~description="OCaml Radio!", ~public=true, ~dumpfile="", ~mount="Use [name]", ~name="Use [mount]", ~protocol="http", ~aacplusenc="aacplusenc", ~bitrate=64, ~restart_on_crash=true, ~restart_on_new_track=false, ~restart_encoder_delay=3600, ~headers=[], s) # Metadata update is set by ICY with icecast def aacplusenc_p(m) "#{aacplusenc} - - #{bitrate}" end output.icecast.external(id=id, process=aacplusenc_p, bitrate=bitrate, start=start, restart=restart, restart_delay=restart_delay, host=host, port=port, user=user, password=password, genre=genre, url=url, description=description, public=public, dumpfile=dumpfile, name=name, mount=mount, protocol=protocol, header=true, restart_on_crash=restart_on_crash, restart_on_new_track=restart_on_new_track, headers=headers, restart_encoder_delay=restart_encoder_delay, format="audio/aacp", s) end output.icecast.aacplusenc( host = "127.0.0.1", port = 8000, password = "password", mount = "/mountpoint.aac", bitrate = 48, input.oss()) However, when I used the same configuration on FreeBSD it would make a connection to the Icecast server but would not send audio. I was able to successfully connect to the connected mountpoint using curl, but only the stream's headers would come through. Here is the on screen info: # liquidsoap -v --debug /tmp/icecast.liq 2009/05/25 11:45:13 >>> LOG START 2009/05/25 11:45:13 [protocols.external:3] Didn't find "ufetch" 2009/05/25 11:45:13 [protocols.external:3] Found "/usr/local/bin/wget" 2009/05/25 11:45:13 [main:3] Liquidsoap 0.9.0+svn (trunk/ liquids...@rev6586) 2009/05/25 11:45:13 [video.converter:4] Couldn't find prefered video converter: gavl 2009/05/25 11:45:13 [audio.converter:4] Using prefered samplerate converter: libsamplerate 2009/05/25 11:45:13 [threads:3] Created thread "generic queue #1". 2009/05/25 11:45:13 [threads:3] Created thread "root" (1 total). 2009/05/25 11:45:13 [root:3] Waking up active nodes... 2009/05/25 11:45:13 [source:4] output(dot)icecast(dot)aacplusenc gets up 2009/05/25 11:45:13 [source:4] src_3529 gets up 2009/05/25 11:45:13 [src_3529:4] Activations changed: static = [output(dot)icecast(dot)aacplusenc:output(dot)icecast(dot)aacplusenc], dynamic=[]. 2009/05/25 11:45:13 [src_3529:4] Enabling caching mode (active source) 2009/05/25 11:45:13 [output(dot)icecast(dot)aacplusenc:4] Activations changed: static=[output(dot)icecast(dot)aacplusenc], dynamic=[]. 2009/05/25 11:45:13 [output(dot)icecast(dot)aacplusenc:4] Enabling caching mode (active source) 2009/05/25 11:45:13 [src_3529:4] Activations changed: static=[src_3529, output(dot)icecast(dot)aacplusenc:output(dot)icecast(dot)aacplusenc], dynamic=[]. 2009/05/25 11:45:13 [output(dot)icecast(dot)aacplusenc:2] Creating external encoder.. 2009/05/25 11:45:13 [output(dot)icecast(dot)aacplusenc:3] Connecting mount /mountpoint.aac for [email protected]... 2009/05/25 11:45:14 [output(dot)icecast(dot)aacplusenc:3] Connection setup was successful. 2009/05/25 11:45:14 [root:3] Broadcast starts up!

Doing a ps on the Linux version I noticed this: # ps auxww |grep aacplusenc 1004 18291 0.0 0.0 1772 484 pts/5 S+ 11:47 0:00 /bin/ sh -c aacplusenc - - 48 1004 18292 3.8 0.0 2036 784 pts/5 S+ 11:47 2:02 aacplusenc - - 48 However, the same command on the FreeBSD machine revealed that the aacplusenc encoder was not running. Furthermore, I did a test to see if aacplusenc was even running by modifying the config: def aacplusenc_p(m) "#{aacplusenc} - - #{bitrate}" end replaced with: def aacplusenc_p(m) "touch /tmp/hello" end As it turns out, the "touch /tmp/hello" never even executed, so it appears that there is a problem with the way that the pipes are being setup on FreeBSD? Does anyone have any thoughts? Any help would be greatly appreciated!
