The moment everyone's been waiting for. now you can play mp3 directly from the Compact Flash card in audrey. Here is how to do it.

1. you must have root access
2. merge multiple mp3 files into one huge mp3 file (i am not sure if there are programs out there that can merge multiple mp3s into one but i use winamp to merge multiple mp3s into one huge wav first then use a file writter pluggin (i use chun-yun's file writter pluggin from winamp.com) to write the wav back into mp3 format)
3. insert cf card in audrey
4. type devb-cf or devb-cf -c (for checksum display)
5. fs-cifs to a share (if you don't know how to mount a share you can search this board for tips on how to do it)
5. cp /share/music.mp3 /dev/cf
(you can probably save from the web if you rename .mp3 to .zip and save to the cf directly, follow my earlier posts)
6. open media player > file open > type /dev >select cf
see note 1 if you want to use phjuke. since there you are playing from the cf, media player works perfectly without skips. (Dont use the stylus if you are surfing the web, use the keyboard to navigate or the music will skip) Both are installed in my images.
7. you are now playing the mp3 file directly from cf.

note 1. in order to make phjuke recognize that there is a mp3 file on the cf card you must create a link to the cf card. type this in the prompt
1.ln -s /dev/cf music.mp3
2. open phjuke >command > settings > and put a / under starting directory > hit ok >hit home
3. tap the music.mp3 file

since you can only store one file so merging your mp3 files is a must. fast forward/backward will cause the music to overlap and you can not skip to the next song since only one huge file is allowed. there may be a way to append separate files but i have not figured out how to do it. you can use this method to put any single file on the CF card , i.e. text file (ebook anyone) and use ped to read it. like i said you can only store one file on the CF as of now. enjoy...

Interesting. It was once mentioned here that you could read and write tar files on the CF. There is a filesystem available for Linux called arcfs that basically allows you to mount a tar file or other archive file and use it as a filesystem. If this could be ported to QNX it might finally be possible to use the CF for storage.

Infinity,

I'm running your InfinitySpecial1.1a.cf on my Audrey. All was great until I tried playing MP3s from the CF card. I've got a Scandisk 32mb card and I've used it MANY times without any problems on Audrey. When I try to play an MP3 off the CF card I get smooth playing for the first 1% of the song, but then it starts to skip BADDLY after that 1% of the song. The song's orginal size is only 9.08mb and is encoded at 128 bitrate. I've tried using Diskprobe (Works for flashing images for me.) - I've tried using mkcf.exe along with Diskprobe to pad the file - Also I've tried using the command cp with Audrey connected to my Windows share. At first all seems to be fine, but then it starts skipping with all 3 methods. I'm running XP Pro, so I've been limited on my options of flash writing. I've also tried diffent bitratres and different sizes, no luck.

Help? Anyone?

Thanks!

Ajingle

I found that phjuke will speed up the music so much that eventually it will overlap about 20 seconds into the song. SO DON'T USE PHJUKE to play from the CF. you have to USE PHPLAY,media player. I created a 28 minute mp3 file containg a bunch of songs and put it on a 32mb sandisk. phplay can play the whole file without any problems. you will experience a bit of skipping if you do heavy browsing and if you use the stylus to scroll on webpages.

oh i forgot to mention this to everyone who are using this method of playing mp3. You should chmod -wx /dev/cf. The cf should be read only to prevent audrey from corrupting the cf file. you can put devb-cf in your boot.sh to load the cf driver at boot. so if you have a cf card in the cf slot it will get recognized at boot. even if you don't have a cf card in the slot it won't harm to load the driver at boot cause you can insert the card after boot and it will automatically get recognized.

Thanks for the insight, Infinity. All is good now. Just incase anyone is having problems merging MP3's (lack of good codex, no program, etc.) I figured out that you can use a simple HEX editor and insert a song at the beginning of another song or at the end without changing the bitrates. It's some what faster, but it CAN confuse the crap out of a Windows machine if the bit rates of the song you're merging differ greatly. So far, 128 through 192 seem to merge well, though it gives false read-outs. (Such as bitrate and time of the track.) The hex editor that I've had the best luck with is XVI32. It's free and VERY simple. You can get it at download.com After you merge the songs, then you can write it directly to the card, using Diskprobe. You dont need to pad the file like with images. (mkcf)

All seems to work alright, though I'm sure it could just be luck.

Also, if anyone is using Audrey in their cars, like I am....you might want to take some time and check the temperatures that Audrey might be going through before you leave her in the car. In my Camaro with a black dash on a 89 degree day, the surface of the dash spent two hours at 174 degrees!!!!!!!!!!!!!!!!! Thats almost TWO TIMES the outside temperature. I dont know if this shockes you as much as it did me, but I now know why my radar detector became a paper-weight after a week in the sun. They said it was rated to withstand temperatures up to 125, I thought I was safe. Nope. I used an iButton attached to my dash to record the entire days temperatures and print out a graph. By the way, has anyone figured out any drivers or programs to connect an iButton reader to Audrey? Just wondering.
