C674x MP3 Decoder Streaming

Brian Boru

Hi,

I would like to develop an application to play (decode in real-time) MP3 files using a C674x DSP. This would require an MP3 decoder, which is available for C674x here:

Before I spend time trying to set this up, I want to ask if it is possible to use this decoder to stream MP3 files and not just decode an MP3 file to a PCM file. I would like to stream MP3 files, so decoding PCM samples and outputting via McASP on-the-fly. Is this possible using this example MP3 decoder?

Thanks

Hi,

According to MP3 datasheet, it should be able to stream MP3 files and able to decode PCM samples on the fly.

May be, you can check it as the mp3 codec release package will also have a standalone test application.

This might be useful for you : http://processors.wiki.ti.com/index.php/How_do_I_Integrate_new_codecs_into_DVSDK and also check the below e2e post which might be of some help:

Hi Sivaraj,

Thanks for your response. I need to integrate this into a SYS/BIOS project, where I will be expanding on one of the C674x BIOS PSP driver examples. I set this up using makefiles and cfg files and build from command line. Do you know if it is possible to link the MP3 decoder library, mp3dec_tii_l1l2l3_ELF.l64P, into such a SYS/BIOS project? How can a binary such as this be linked into a SYS/BIOS project such as this?

Thanks & regards

Brian
