Re: [mad-dev] Cross compiling libmad for ARM
by Gareth Bransby 08 Mar '02

I had a go at what you suggested but this had no effect, it came up with exactly the same error. From what i can see from the error, it is looking in the linux/ directory in the libmad/ source directory, not in /usr/src/linux. I tried doing what you suggested but making the link in the libmad directory rather than in /usr/src, so now i have a link mad-0.13.0b/libmad/linux -> /usr/local/arm/gnu/release/arm-linux/include. Now it finds errno.h ok but generates different errors decoder.c: In function 'mad_decoder_finish': decoder.c:91 'EINTR' undeclared (first use in this function) decoder.c:91 (Each undeclared identifier is reported only once for each function it apears in.) decoder.c In function'send_io': decoder.c:120 'EINTR' undeclared (first use in this function) decoder.c In function'recieve_io': decoder.c:142 'EINTR' undeclared (first use in this function) decoder.c:145 'EAGAIN' undeclared (first use in this function) make: *** [decoder.lo] error 1 I am wondering are there some required files that are needed for cross compiling that i have not installed?

Porting on TOSHIBA TX3911
by davidlee 06 Mar '02

06 Mar '02

Dear All: I'm porting MAD to TOSHIBA TX3911, but it seems my cross compiler mipsel-linux-gcc can't compile the asm instruction "madd" that surpported by TX3911 hardware. I wand if anybody can tell me eithe I should change compiler or I shoud change compiler's parameter and how. Thanks in advance. 李大冀 Email: davidlee(a)gv.com.tw

Dear All: My host is PC, and I'm porting MAD to my Target Board with Toshiba TX3911 CPU. There is many configure tools ,but I don't how to use them to create proper Makefile that can compile TX3911's "madd" instruction. BEST REGARD 李大冀 Email: davidlee(a)gv.com.tw

What problems can I expect when porting MAD to a 32 bits MIPS VR4111
by Jeroen T 02 Mar '02

02 Mar '02

Hi. I am developing software to play MP3 files from a MIPS VR4111. I connected a IDE harddrive to it to store MP3 files. The software for the harddrive is almost finished and it supports FAT32 (root directory only). Now I still got some problems with porting MAD to the MIPS. It's compiling, and it seems to decode, but the outputdata is not what I expected. I decode a 1 second 440 HZ sinus, and when I decode it on a PC the outout data is OK. On the MIPS the outputdata looks like multiple sinusses with multiple frequencies added to each other. I looked for problems in the multiply functions and probable little/big endian issues. I don't know what to look further to. What can be the problem? When I have MAD running on the MIPS, I will have a stand alone MP3 jukebox with large harddrive! Hope someone can give some further tips. Jeroen _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com

tics
by Mathieu Dube 02 Mar '02

02 Mar '02

Hi, Im decoding mp3s with a program I wrote using libmad. With most mp3s it works fine but with some it does some tics that it doesnt do if I play the mp3 in xmms. Maybe thats a coincidence but all the mp3s that have tics have a 128kbps bitrate. Did anybody have that type of problems?? Would it be in the reading/decoding or the writing that the problem would be? Thanks -Mat -- Mathieu Dube -- mdube(a)8d.com 8D Technologies Inc. http://www.8d.com

Thank you suggestion , It's my First time deal with MP3 and MAD.
