I want the cheapest setup and a couple other more expensive setups for
my LUG talk.
Correct me or give me more ideas.... here is what I think:
Cheap:
600Mhz CPU
G400-TV
- I've run the G400-TV for output before, I guess capture is ok... comments?
That is fine for cheap. What about recording? Video encoding in
software takes a lot of CPU for good quality. Maybe this should be
600-1000 Mhz.
A low end system could handle encoding video to mpeg1 or nupplevideo
formats in software, or use a hardware mpeg encoder like a pvr-150 card.
This system will be slower for doing things like ripping CDs to mp3 or
other CPU intensive tasks (plugins for whatever).
I'd like to review a configuration with the LUG for someone that has $30
(for a G400-TV) and an old used 600Mhz "free computer". Then go up from
there.
I had a 800 Duron that worked ok, I guess I didn't do much capture. If
I remember right... I was only able to encode with xvid (or maybe it
was divx) at 320x240... so that would be limiting. Playback was always
amazing with the G400, I remember something like 4% of the CPU being
used by Mplayer. But your right, encoding is a problem at such a slow
speed without a hardware encoder. That must be one of the reasons I
have a 2.4GHz now, I forgot.
Maybe I'll make a matrix of configurations. A PVR-150/250 would allow
for a slow CPU.
Mid-Range:
600+ CPU
G400DH
SBLive
- My setup
How about 1-2 Ghz? CPUs in that range are pretty cheap these days and
you can't find anything new at slower speeds (intel/AMD anyways).
You should mention commercially available video cards that do tv-out.
The most popular are nvidia and ATI based, and both have XFree86 or Xorg
drivers that support the tv-out, and can be had for cheap.
I must be a total Framebuffer biggot. I bought a Radeon for this
project along time ago, but couldn't get the framebuffer to work on
TVout. At that time there was a patch from a PowerPC guy that made it
almost work to VGA. Thats why I got the G400DH.
Are there ANY success stories with TVout and Framebuffer with ATI or
Nvidia? I just hate running X for this sort of thing.
High-End:
600+ CPU
PVR350
- Does a SBLive add anything? Doesn't a PVR350 have audio and video out.
And high end I would suggest 2+ Ghz. With the higher CPU the intensive
tasks will be much quicker (think ripping a CD in way less time) and
give you the freedom of utilizing a plugin for transcoding your videos
into DVD format and burning them much faster. Everything will be more
responsive and you could take advantage of animations and picture in
picture support (not that we have that yet, maybe in 2.0).
Also be careful of the pvr-350. It's good on paper but I don't think
the drivers are good enough to have a great experience with mplayer or
xine (audio / video sync problems).
Out of the PVR 150,250,350... which has the most supported functions?
I thought the most feature rich would be the best, but apparently Linux
doesn't support the 350 very well? The 350 is the only with hardware
decode right? Rob, what do you have? And what is the "best"?
MythTV vs Freevo:
1. MythTV has "pause"
2. Freevo can do Framebuffer (I wonder if QT can sit on SDL to make
MythTV do framebuffer)
3. Freevo architecture is plugin/helper oriented.. Myth is not?
Thanks for answering my questions...
