C64XPLUSCODECS: MP3 decoder - missing static library in COFF format

user6160156

Part Number: C64XPLUSCODECS
Other Parts Discussed in Thread: TMS320DM6435

Hello Everybody,

let me introduce myself. I am developer responsible for implementation of MP3 decoder in our products. I am kindly asking you for a help ( linking of static library issue ).

I am trying to use MP3 codec for c64p DSP downloaded from that link

http://software-dl.ti.com/dsps/dsps_public_sw/codecs/C674X_Audio_Codecs/01_00_001/index_FDS.html

but I am unable to link the static library mp3dec_tii_l1l2l3_ELF.l64P. The problem is that the library is in ELF format but our project requires library in COFF format. The COFF format should be provided according to doc file

MP3_L1L2L3_Decoder_C674X_UserGuide.pdf

Chapter 2.4 says

2) Verify that the codec object libraries mp3dec_tii_l1l2l3_COFF.l64P and mp3dec_tii_l1l2l3_ELF.l64P exists in the \Lib sub-directory.

But the mp3dec_tii_l1l2l3_COFF.l64P is missing in the \Lib sub-directory of mp3 decoder.

Is there any way how to get the static library in COFF format? Could you please provide the missing file?

Thank you very much in advance,

Best regards,

Lukas Dibelka

Lukas,

This is a slightly older package so I don`t have this installed on my machine to provide exact guidance. Currently the download link is broken so we are working withe Webops team to fix the issue.

Looking at the release notes, the installer seems to be built for both COFF and ELF binaries. Are there any other libraries in the package without the suffix _elf that you have tried to link to your application.

Rahul

Hi Rahul,

I was given the link to a site where I found the link to the mp3 decoder.

The name of the installer file ends with _elf.exe so I quess that the package contains elf binaries only.

It would help me a lot if you find a package containing binaries in COFF format. Thank you very much in advance.

Lukas

Lukas,

Can you please access the COFF version from the installer here:

http://software-dl.ti.com/dsps/dsps_public_sw/codecs/C64XPlus_Audio/index_FDS.html

I believe the C674x DSP users need to use the ELF version however, since you are using C64x+ device and older COFF based binary, you may be able to use the COFF binary form mp3_decoder 1.31 release.

Rahul

Hi Rahul,

thank you very much for the link. I have successfully downloaded and linked the mp3 decoder library. Can I ask you for mp3 encoder for the same processor?

Thank you.

Lukas,

TI does not have a MP3 encoder package. All audio codec packages available from TI are on the link that I shared above

However, our third parties Ittiam (www.ittiam.com) and Spirit DSP (www.spiritdsp.com) have MP3 encoders available on the C64x+. Please contact them for more information.
