I'm already at 320x240, which I would think would be the lowest decent resolution I'd see. What would you recommend for an easier audio encoding scheme? ---Patrick M [EMAIL PROTECTED]:3784715-- "You know, this is how the sum total of human knowledge is increased.

There is a problem with nehemiah CPU's with model 9 that prevents ffmpeg
(libavcodec/mplayer) from detecting mmx properly...
root:~# cat /proc/cpuinfo
processor : 0
vendor_id : CentaurHauls
cpu family : 6
model : 9
model name : VIA Nehemiah
stepping: 3
cpu MHz : 1000.058
If you have such a CPU, your lucky, there's a patch for it, if not I
can't help you.
In the source off mplayer in mplayer/libavcodec/i386/cputest.c
and/or in ffmpeg libavcodec/i386/cputest.c
Youll find the lines:
} else if (ebx == 0x746e6543 &&
edx == 0x48727561 &&
ecx == 0x736c7561) { /* "CentaurHauls" */
/* VIA C3 */
cpuid(0x8000, eax, ebx, ecx, edx);
if ((unsigned)eax < 0x8001)
goto inteltest;
cpuid(0x8001, eax, ebx, ecx, edx);
edx = 0x1380b035; // <- Add this for Nehemiah mmx ->
rval = 0;
if( edx & ( 1 << 31) )
rval |= MM_3DNOW;
if( edx & ( 1 << 23) )
rval |= MM_MMX;
if( edx & ( 1 << 24) )
rval |= MM_MMXEXT;
return rval;
I've got the same problem on my V1000, and it prevented me from trowing
it ut of the window... (or even worse, install M$ on it ;)

You may be able to allocate more buffers when you load the module for your card. I'm not sure which module your uses (bt878?) but run modinfo on it to see if that's possible. -Rob --- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.

RE: [Freevo-users] Recording issue with mencoder
Run top whilst recording something and watch the memory usage. When that hits the maximum specified by your VCR_CMD (freevo default is 64meg) you will start dropping frames. What causes it to increase is having cpu maxed out at 99%. You'll need to either increase your buffer (probably don't have enough ram for this), or decrease the cpu being consumed. An easy way to do is to not encode audio to mp3 on the way, or decrease the resolution you are capturing at . . .
