basename not working as expected from find -exec
I have the following files in a directory

Code:
> ls -1 /tmp/test/dir/
file with spaces 1.ogg
file with spaces 2.ogg

I am running the following to echo the filenames but alter the file extension on the files to .mp3 instead of .ogg ( I am going to run ffmpeg against the files ultimately, but keeping the example simple for the sake of the thread).

Code:
find /tmp/test/ -type f -name "*.ogg" -exec echo {} "$(basename {} .ogg).mp3" \;

I expect the output to be:

Code:
/tmp/test/dir/file with spaces 2.ogg /tmp/test/dir/file with spaces 2.mp3
/tmp/test/dir/file with spaces 1.ogg /tmp/test/dir/file with spaces 1.mp3

But instead it fails to remove the .ogg and I end up with:

Code:
/tmp/test/dir/file with spaces 2.ogg /tmp/test/dir/file with spaces 2.ogg.mp3
/tmp/test/dir/file with spaces 1.ogg /tmp/test/dir/file with spaces 1.ogg.mp3

* Note the ".ogg.mp3" extension *

A basic echo works as expected:

Code:
> echo $(basename /tmp/test/dir/file\ with\ spaces\ 1.ogg .ogg).mp3
file with spaces 1.mp3

I can only assume this has something to do with the space between {} and .ogg in the confines of find.

How can I run this so it produces the desired filename?

oggdec

oggdec(1)							   Vorbis Tools 							 oggdec(1)

NAME

       oggdec - simple decoder, Ogg Vorbis file to PCM audio file (Wave or RAW).

SYNOPSIS

       oggdec [ -Qhv ] [ -b bits_per_sample ] [ -e endianness ] [ -R ] [ -s signedness ] [ -o outputfile ] file ...

DESCRIPTION

       oggdec decodes Ogg Vorbis files into PCM-encoded ("uncompressed") audio files, either Wave or RAW format.

       For  each input file, oggdec writes to a filename based on the input filename, but with the extension changed to ".wav" or ".raw" as appro-
       priate.

       If the input file is specified as - , then oggdec will read from stdin, and write to stdout unless an output filename is  specified.  Like-
       wise, an output filename of - will cause output to be to stdout.

       Writing	Wave format to stdout is a bad idea.  Wave requires a seekable medium for the header to be rewritten after all the data is written
       out; stdout is not seekable.

OPTIONS

       -Q, --quiet
	      Suppresses program output.

       -h, --help
	      Print help message.

       -V, --version
	      Display version information.

       -b n, --bits=n
	      Bits per sample.	Valid values are 8 or 16.

       -e n, --endian=n
	      Set endianness for 16-bit output.  0 (default) is little-endian (Intel byte order).  1 is big-endian (sane byte order).

       -R, --raw
	      Output in raw format.  If not specified, writes Wave file (RIFF headers).

       -s n, --sign=n
	      Set signedness for output.  0 for unsigned, 1 (default) for signed.

       -o filename, --output=filename
	      Write output to specified filename.  This option is only valid if one input [file] is specified, or if raw mode is used.

EXAMPLES

       Decode a file enabler.ogg to enabler.wav
	as little-endian unsigned 16-bit (default options):
	      oggdec enabler.ogg

       Decode a file enabler.ogg to enabler.raw as headerless little-endian unsigned 16-bit:
	      oggdec --raw=1 enabler.ogg

       Decode enabler.ogg to enabler.crazymonkey as unsigned 8-bit:
	      oggdec -b 8 -s 0 -o enabler.crazymonkey enabler.ogg

       Decode enabler.ogg to enabler.raw as big-endian signed 16-bit (any of the following):
	      oggdec -R -e 1 -b 16 enabler.ogg
	      oggdec -R -e 1 -b 16 -o enabler.raw - < enabler.ogg
	      oggdec -R -e 1 -b 16 - < enabler.ogg > enabler.raw

       Mass decoding (foo.ogg to foo.wav, bar.ogg to bar.wav, quux.ogg to quux.wav, etc.):
	      oggdec *.ogg
