Rendering 2.3 tags with libid3tag-0.15.0b
by Vince Busam 23 Jan '04

23 Jan '04

Im trying to render 2.3 tags with libid3tag-0.15.0b and having problems. I understand this may not be a feature of this code but Im close. Ill try to make this short, but some detail might be useful. I have a LGPL library (http://www.busam.com/skyland/iavc) for which I am writing a GPL front end. My development environment is Windows. When I use libid3tag-0.15.0b to render tags in an output MP3 file, I see what are almost certainly 2.4 version tags. Neither stock Windows Media Player 9 nor the PhatNoise Music Manager (PMM) (http://www.phatnoise.com) recognizes these tags. Since I use the PMM extensively, I require compatibility with it. The files ripped by PMM have 2.3 tags at the beginning of the mp3 file and version 1 tags at the end. When I do m_libmad.getID3tags(), I get a id3_tag structure with the ID3_TAG_OPTION_ID3V1 bit set. When I rendered the tags I got version 1 tags (no surprise because of the set bit). After removing that bit and defining ID3_TAG_VERSION as 0x0300, I get ID3 tags that are close to 2.3 tags. At least PMM recognizes that there are tags and shows most of them. Windows Media Player 9 still doesnt show any sign of recognizing these tags. Next I found that in compat.gperf that TYER is set to obsolete and that translate_TCON removes parenthesis. Before I get any deeper, I thought Id check to see if there is a better suggestion as to how to get 2.3 tags rendered. Thanks, Vince

compile fail for madplay with alsa-1.0.0.rc2
by Florin Braescu 07 Jan '04

07 Jan '04

Hi everybody, I have tried to compile the madplay app using alsa-lib and alsa-utils 1.0.0rc2 and linux kernel 2.6.1-rc1. I use also gcc 3.3.2. The compile process failed. It seems that the audio_alsa.c use sys/asoundlib.h instead alsa/asoundlib.h. However modifying that it didn't help either. I want to mention that the 0.9.8 version of alsa-lib and alsa-utils permit the compiling of madplay and work just fine. Maybe some dev have some time to take a look at this situation.

Decode directories, how to?
by jrx＠telia.com 02 Jan '04

02 Jan '04

Hi list, I would like to decode a whole directory in a bunch. Probably I have to use some kind of ordinary *nix command (I'm from the other side), but I can't figure it out, and I can't find any description of this presumably easy matter in man madplay Thanks in advance. jrx

Complemetary questions about decoding a dir and about formats
by jrx＠telia.com 01 Jan '04

01 Jan '04

Hi list and thanks Rob for your answer, A few complementary questions, again maybe a bit OT: I do not really need wav format (by the way, is wav in some way a ms invention?). What I'm trying to do is to decode a lot of mp3s to a format usable for listening with a non-mp3-capable cd player, i.e in my car, and then burn them to CDs with k3b. At the first stage (before burning) I would like to save the mp3s as individual output files in another directory than the mp3s. 1. Is .cdr a format for my purposes? 2. Shell scripts are a bit beyond my capacity for the moment (but I'm learning fast). What do you mean with "The above is for Bourne-derived shells; hopefully yours is not of Csh variety."? What about this? If i navigate to the directory where the mp3s are and then: for file .mp3; do madplay -o -v $file.cdr $file; done Where in this little script should I put the target directory name (called "cdr)? What does "done" mean? Close?

I would like to have it in wav. If you're trying to burn an audio CD, try: madplay -o cdda:track.cdr The result is a raw CD audio track ready to be burned. If you really must have a WAV file, you'll have to specify all the parameters yourself: madplay -o foo.wav --stereo --bit-depth=16 --sample-rate=44100 -- Rob Leslie rob(a)mars.org --__--__-- Message: 4 From: Rob Leslie <rob(a)mars.org> Subject: Re: [mad-user] Decode directories, how to?

Problem with 24 bit output on M-Audio Revolution 7.1
by Jason Clouse 21 Dec '03

21 Dec '03

Greetings! I just got hold of an M-Audio Revolution 7.1 and decided to start playing around with it. I've got the latest CVS of ALSA and AlsaPlayer installed and I can successfully get sound of the card. I'm having some trouble, however. I read that the Revolution has a pure 24/192 signal path from start to finish, and that madplay can take advantage of this. I tried running madplay with the '--bit-depth=24' option but it told me that the card couldn't handle 24 bit output, and that it was dropping back to 16. Did I miss something? Jason Clouse

Madlib Slow?
by Tomas 15 Dec '03

15 Dec '03

Hi! I have compiled the madlib and tried to decode MPEG2 frames on a armv4 chip (AT91RM9200) with processor clock ~180 MHz but it seems too slow. I need to decode a MPEG2 (layerII) frame (say 224kHz) each 24 ms. I have cross-compiled the madlib with the following configuration CC=arm-elf-gcc RANLIB=arm-elf-ranlib LD=arm-elf-ld AR=arm-elf-ar ../mad- 0.14.2b/configure --enable-speed --enable-fpm=arm --disable-nls --disable- mmap --disable-debugging --host=arm-elf arm-elf Correct configuration to enable speed or can I try something else? Is any body sucessfully running this on this processor or similar? /Tomas

Questions about how to build a ARM based madplay
by Kzhang 10 Dec '03

10 Dec '03

Hi All, I download both of mad-0.14.2b and madplay-0.15.0b, and I try to build a ARM based player, but I met problem to change gcc to arm-linux-gcc with ./configure command. I work on a ReHat 9.0 PC as host, and use arm cross compiler 2.95.3 toolchain. Please give me some tips how to build it, I very appreciate for your help. Thanks. Keji Zhang kzhang(a)neomagic.com

Build problem with cygwin/mingw
by Jedediah Smith 14 Nov '03

14 Nov '03

Following steps were followed: ./configure --host=mingw32 --prefix==/cygdrive/c/source/vc/mixer/libmad Configure step goes fine. The prefix is the dir I want to install to e.g. c:\source\vc\mixer\libmad which already exists. make also works fine make install goes like this: -------------------------------------------------------------------------------- $ make install make install-recursive make[1]: Entering directory `/cygdrive/c/source/vc/mixer/libmad-0.15.0b/libmad-0 .15.0b' make[2]: Entering directory `/cygdrive/c/source/vc/mixer/libmad-0.15.0b/libmad-0 .15.0b' make[3]: Entering directory `/cygdrive/c/source/vc/mixer/libmad-0.15.0b/libmad-0 .15.0b' /bin/bash ./mkinstalldirs /cygdrive/c/source/vc/mixer/libmad/lib /bin/bash ./libtool --mode=install /usr/bin/install -c libmad.la /cygdrive/c/s ource/vc/mixer/libmad/lib/libmad.la /usr/bin/install -c .libs/libmad.lai /cygdrive/c/source/vc/mixer/libmad/lib/libm ad.la /usr/bin/install -c .libs/libmad.a /cygdrive/c/source/vc/mixer/libmad/lib/libmad .a ranlib /cygdrive/c/source/vc/mixer/libmad/lib/libmad.a c:\mingw\bin\ranlib.exe: /cygdrive/c/source/vc/mixer/libmad/lib/libmad.a: No suc h file or directory make[3]: *** [install-libLTLIBRARIES] Error 9 make[3]: Leaving directory `/cygdrive/c/source/vc/mixer/libmad-0.15.0b/libmad-0. 15.0b' make[2]: *** [install-am] Error 2 make[2]: Leaving directory `/cygdrive/c/source/vc/mixer/libmad-0.15.0b/libmad-0. 15.0b' make[1]: *** [install-recursive] Error 1 make[1]: Leaving directory `/cygdrive/c/source/vc/mixer/libmad-0.15.0b/libmad-0. 15.0b' make: *** [install] Error 2 -------------------------------------------------------------------------------- It looks like ranlib is being passed the cygwin version of the path but it doesn't recognize it as it's part of mingw and only allows normal Windows paths. What shall I do about this?
