[Freeswitch-users] mod shell stream

Hi there, I'm trying to make a playback of streamed sound data coming from a database. I could make the example included in documentation work (cat file.wav | sox -t wav - $@ -t raw -). However, I can't make it work with same sox options after having uploaded that same file into my PGSQL database and select it instead of a cat command. My shell script is #!/bin/bash psql -h <HOST> -U postgres -E -t -q -d <DATABASE> -c "select <BINARY COLUM DATA> from <TABLE> " | sox -t wav - $@ -t raw - Freeswitch gives me a "sox FAIL formats: can't open input `-': WAVE: RIFF header not found" error message. Has anybody streamed data from database into Freeswitch? Thank you. Bernard
