From 27be5bc72855a0fbbdae230bc144624c9eb85f5e Mon Sep 17 00:00:00 2001 From: Michiel Van Der Kolk Date: Thu, 17 Mar 2005 20:50:03 +0000 Subject: Initial check in dumb 0.9.2 - has a few usages of floating point that should be rewritten to fixed point. seems to compile cleanly for iriver. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6197 a1c6a512-1295-4272-9138-f99709370657 --- apps/codecs/dumb/examples/dumb.ini | 44 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 apps/codecs/dumb/examples/dumb.ini (limited to 'apps/codecs/dumb/examples/dumb.ini') diff --git a/apps/codecs/dumb/examples/dumb.ini b/apps/codecs/dumb/examples/dumb.ini new file mode 100644 index 0000000000..6fea2ce50f --- /dev/null +++ b/apps/codecs/dumb/examples/dumb.ini @@ -0,0 +1,44 @@ +# Please edit this file to control the playback quality for 'dumbplay'.
