Hi,
Does anybody get streaming audio working on Assabet /
Neponset?
I got this again and again:
mpg123: Can't rewind stream by 347 bits!
or
Illegal Audio-MPEG-Header 0xce198a68 at offset
0xfffffffb.
Skipped 57794 bytes in input.
Illegal Audio-MPEG-Header 0xa2aa4aaa at offset
0xfffffffb.
Skipped 30713 bytes in input.
First, I configured Assabet kernel to support sound.
I could run "splay test.mp3" from the "kitchen sink
ramdisk". This is good.
Second, I set up a icecast + shout station and used
RealPlayer in Windows to verify that this station was
working. This is also good.
Then, I set up a streaming client on Assabet +
Neponset.

mpg123: Can't rewind stream by 347 bits!
The mpg123 comes by compiling the code from
mpg123-0_59r-arm32_tar.gz at
ftp://ftp.handhelds.org/pub/apps/sound/.
I modified the makefile (note that audio_oss is
chosen).
linux-arm:
$(MAKE) OBJECTS='decode.o dct64.o audio_oss.o' \
CC=/opt/hardhat/devkit/arm/sa110_le/bin/sa110_le-gcc \
LDFLAGS='-L/opt/hardhat/devkit/arm/sa110_le/lib/' \
CFLAGS='-DLINUX -Wall -g \
-DREAD_MMAP -DOSS -funroll-all-loops \
-finline-functions -ffast-math \
-I/opt/hardhat/devkit/arm/sa110_le/armv4l-hardhat-linux/include/'
\
mpg123-make
The icecast server did get the client (so they must be
communicating) but mpg123 did not work. I also tried
freeamp and xaudio but they did not work, either. Is
there a good binary mpg123 I can ftp?
Can anybody share the experience to make streaming
audio work? Thanks a lot!
