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

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 have tried to decode an old mp3 with various settings to wav with mad, and the decoding seems to work fine. But when I try to burn the wav with k3b, k3b says "wrong format". madplay -v -i -m --output=wave gives "Layer III, 64 kbps, 22050 Hz, single channel, no CRC, 7095 frames decoded, -7.4 dB peak amplitude, 0 clipped samples" Does anybody have any suggestions about what options I should choose when decoding. I would like to have it in wav. Or maybe I should look in my k3b settings for this particular file..?

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?
