Decode time is longer than song time on ARM EP7312?
by Jimmy Lin 13 May '02

13 May '02

Hi all, I have compiled madplay-0.14.2 for ARM with the special following option: --host=arm-linux --enable-speed --disable-debugging --enable-fpm-arm Because, I don't have sound output device on my target right now , so I tried to run madplay with only DECODE on iPaq (StrongARM 210MHz) and EP7312 (ARM 74MHz) for compare. The test.mp3 is 128kbps, 44100Hz, joint stereo, 1m1.2s long. $ time ./madplay -v --output=wave:/dev/null test.mp3 iPaq: 11.857s EB7312: 1m5.539s What I got wrong? Does it mean my platform can't play mp3 smoothly? Any idea to improve the performance in that case? Thank you for your suggestion! Regards, Jimmy

Cross compiling again
by Gareth Bransby 06 May '02

Hi, I maganged to get mad cross compiled with with an arm-linux cross compiler but it turs out that is not the wan I should be using. I have jsut built an arm-elf cross compiler and it works fin on simple programs. Now when i do ./configure I get the error : configure: error: can not run test program while cross compiling I understand why it can't run the test program but it never had a problem with the other cross-compiler. I tried giving it the --build=1686-linux along with the --host=arm-elf option so it would _know_ it was cross compiling but this made no difference. Is htere some other optin that i can pass to configure to stop it running test programs?

Error 0x0101 ... using libmad...
by naso 03 May '02

Hi everybody, I'm Simone from Genoa. I'm using minimad for WinCE, so I had to modify it in some part. Now I believe I've done a good job, because the function "decode" does something... it calls "input" then calls "error". The message I get from "error" is the sequent: "decoding error 0x0101 at byte offset 0" Does someone know what does it means (I've understood only that the error happens at the beginning of the file ".mp3", but the code 0x0101 doesn't tell me nothing...)? Thank you all. ---- Simone

Equaliser style effect.. i.e visualisation.
by Thomas Rathbone 02 May '02

In what stage of the decoding process can i find the information I would need to create an equaliser (a frequencies bar graph) visualisation? Do I just look at the subband levels or is that totally wrong? Has anybody done this? Much thanks. Tom.

All: How can I go about simply scrolling through the list of genres? I can't quite seem to get what I want. Thanks. -- Neil Hodge nhodge(a)attbi.com
