I think you might need a script to strip the column header ? psql -c "select 1" |cat ?column? ---------- 1 (1 row) -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com) On Saturday, March 3, 2012 at 10:17 PM, Bernard Fluixa wrote:
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
