Speex dev - Oct 2007 - Encode and decode using speex

Hi,
I am new to speex and I am trying to use the sample program given in the
speex document.
I have made some modification to that sample, so that input can be read from
a file and the output can be re-directed to the file.
I tried to encode an audio file using the sampleenc and decode the same by
sampledec.c I am able to do it successfully, but when i try to play the
output file from the sampledec.c, i am able to hear only some noise.

Is it possible for me to encode a sample.wav file to encoded.spx using
sampleenc.c and decode it using sampledec.c and store the output in a
output.wav and play it using aplay? Will I be able to do the above?
Please help me, I am new to speex. If i am wrong please correct me.

Thanks & Regards,
Saravana Kumar

No, sampleenc/sampledec work on raw (headerless) files. Either you'll
need to work on raw files, or else just use speexenc/speexdec. The
latter are more complex, but they produce portable files.

Hi,
    I am trying to cross compile the speex for the arm linux.
I configured using the following command:
./configure --host=arm-linux --prefix=/opt/ARM/eldk/usr/local
--with-ogg-dir=/opt/ARM/eldk/usr/local
--with-ogg-includes=/opt/ARM/eldk/usr/local/include
--with-ogg-libraries=/opt/ARM/eldk/usr/local/lib
I have separately compiled the ogg for the arm linux and specified the path
when configuring compile for the speex.

I am able to successfully compile, make and make install.
We are not able to see the shared objects file libspeex.so.xxx, but the
.so.xxx file is created when i compile the same for the x86 Linux.

Then I tried to compile the sample program that comes with the speex
documentation, using the following command.
arm-linux-gcc -o encode -I /opt/ARM/eldk/usr/local/include -L
/opt/ARM/eldk/usr/local/lib -lspeex  sampleenc.c
I am getting the following error:
/tmp/ccGmYcxv.o: In function `main':
sampleenc.c:(.text+0x20): undefined reference to `speex_encoder_init'
sampleenc.c:(.text+0x58): undefined reference to `speex_encoder_ctl'

sampleenc.c:(.text+0x20c): undefined reference to `speex_bits_destroy'
sampleenc.c:(.text+0x230): undefined reference to `speex_nb_mode'
collect2: ld returned 1 exit status

But, I am able to compile the same sample program for x86 linux.
Should I do any other ARM specfic configuration other that above for
compiling the speex?
Please help me, in solving this error.

Thanks & Regards,
Saravana Kumar
