I am trying to use the Gumstix with the audiostix and the network interface to encode the Line-in into MP3 and send it to the internet. Now I have issues with lack of power processing, but it could be compiler optimization I am missing. During compilation, I had to do ln -s arm-linux-uclibc-* to xscale-linux-uclibc-* because at one point, it couldn't find the xscale-* binary. That was the only change I have done from the svn buildroot I checked out plus adding my own .mak file for mp3 encoding . Now I was beable to encode at 22kbits/sec at 16khz, but that about it... anything higher is not working. I have the 400mhz gumstix. Anyone have hints on how I could improve my situation ? Thanks Marc O. |

Also, Im using the default gumstix kernel it came with it : Linux gumstix 2.6.11gum #1 Mon Aug 15 11:33:49 PDT 2005 armv5tel unknown Is there any way to see per process CPU usage also ? Marc O.

What encoding library are you using, and how are you compiling it?

I have tryed lame with darkice, but the best result was using lame and liveices. I 'll have to rebuild the liveices code before I show it to you. Those are the 2 .mk file I use. They are not perfect. still learning how to build those file correctly http://64.235.196.30/lame.mk http://64.235.196.30/darkice.mk I have tryed it without the libfloat and it was even slower also my ln -s of the arm to the xscale isn't require from my last checkout. Is it false hope to do encoding on the gumstix or it should be posible without much problem ? Marc O.

Do you really need to encode to mp3. I have been using the flac encoder (http://flac.sourceforge.net) which has a fixed point implementation which workes pretty well. Still haven't gotten around to tidy the makefile, but wil do so soon :) Simon Marc Olivier Chouinard wrote: > I have tryed lame with darkice, but the best result was using lame and > liveices.

I need to send to a IceCast compatible server MP3 stream in different codec, (from 24kbits/sec 22kh mono to 128kbits 44khz stereo). This is not on a local private network but over the internet. We are looking to build alot of them... Our other option is to go with a mini itx system, but I like more the gumstix format. I havent figured how to do the cassing yet, but I want of course, to get this working first. Also, anyone got pppd to compile and work on the gumstix ? Marc O.

The problem is that the LAME encoder uses a lot of FP math in the encoding, and FP is enormously slow on the PXA255, which has not hardware FPU. If you can find an integer-math MP3 encoder, you'll probably find much better performance. Intel's IPP might do the job, but I believe it's linked against glibc not uclibc, so it might be tricky getting it to work alongside the buildroot. Alternatively, you might be able to find an integer MP3 encoder somewhere else. The reason FLAC works pretty good is that any lossless encoder will more or less by definition not be using FP math, since you'll lose data in the rounding errors with FP math. So since it's all-integer math, it will run much faster on the PXA255. It looks like the Shine encoder has a fixed-point version available -- haven't tried it, and it looks like it'll need to be tweaked a little to remove some RISC-OS specific stuff, but here's the link: http://www.mp3-tech.org/programmer/encoding.html -- scroll down to bottom of page.

MAD is a mp3 decoder, and also explain why it included in the gumstix buildroot. I have gaveup. I do not think it can perform to do 128kbits encoding sadly Thanks alot for your inputs in this.

DOH! I'll just chalk that one up to an 'out-of-coffee error'. <G> BTW, I couldn't find /any/ integer MP3 encoders, but I /did/ find WavPack (http://www.wavpack.com), for those of you who don't need MP3. I don't know whether or not it will easily work with gumstix. Marc Olivier Chouinard wrote: > MAD is a mp3 decoder, and also explain why it included in the gumstix > buildroot. > > I have gaveup.

MP3 encoding is a rather cpu-intensive task when compared to decoding, and arm is a RISC engine, which means it has mostly timing-predictable simple instructions, which means complex operations have to be implemented in software (even though the xscale family has some support for vector integer math through coprocessor 0, which could improve things a bit, but AFAIK nobody appears to use that on linux), which finally means it would probably require a higher cpu clock (you can overclock your gumstix quite a bit using cpufreq, I've done it, but I can't say it's safe).

So, I guess it begs the question. Is there an FPU co-processor board of some kind the gumstix could talk to as a daughterboard? Ala, the old 8087 co-processor days.

I've followed the instructions on the wiki for building on OS X and I'm getting this error: Resolving svn.rungie.com... done. Connecting to svn.rungie.com[216.139.227.50]:80... connected. HTTP request sent, awaiting response... 401 Authorization Required Authorization failed. make: *** [/Users/scottharris/Programming/Gumstix/scudderfish/sources/ dl/mtd-snapshot-20050205.tar.bz2] Error 1 svn.rungie.com requires a password and I'm not even sure what's there. Can anyone working on OS X give me a hand? Thanks! -Scott |

I got a fresh copy og the scudderfish branch at rev 648 and I'm getting the authorization problem again on svn.rungie.com. Is there a way for me to fix/work around this locally?

Try using svn.gumstix.com (I think) instead. The main buildroot has been updated this way. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Files have been moved to http://files.gumstix.com/ -- as Dave Hylands says, the paths have been updated on the trunk -- I guess Dave Smith hasn't merged that in to his branch yet.

How's it going? Regards, Dave |

Regarding the ARM floating point dilemma, the cirrus logic maverick crunch coprocessors sure look interesting: http://www.cirrus.com/en/pubs/appNote/AN253-1.pdf BTW the Cirrus EP9315 ARM9 has stuff that everyone seems to want including floating point coprocessor, ethernet MAC, IDE controller, 3 USB host ports, graphics controller, and audio. This processor can even handle up to 6 channels I2S audio. I'll be testing out several ARM7 and ARM9 SOCs as companion to the PXA255. These include ST Micro STR711, Sharp LH79525, and Cirrus Logic EP7312, EP9301, EP9312, EP9315. -- Doug |
