Hi.
I thought I read that the GP had capabilities for reading mpg and some other video formats. Does it do this with the bios?
movie park reads divx at 10fps. mpg1 should, I believe, be faster to decode. Is it so? can the GP play a mpg at full speed?
..just wondered.. while waiting for mine :)
 
currently the GP32 can only play DivX 4.12 (mpeg-4 avi) encoded videos. but i'm sure it will support mpeg-1 (standard) and such later on, especially when those 256MB SMCs come out. ;)
 
Mpeg 1 should be a lot faster to decode. There is, though, a problem (though I don't know how big it is) for Mpeg1s.
Basically, they're very very big (i.e. larger than a DVD for a film - DVDs are Mpeg2). More to the point, reading an SMC is relatively slow, so its quite possible you wouldn't be able to stream the film off the disk fast enough before you got to the next bit.
But to be honest, whilst I'd love some other formats like .asf, .wmv, .rm, and .mov, Mpeg1 converts so easily to DivX that there's not a huge ammount of point in using it.
Please note, I have no idea how much each of the copyright holders of the formats mentioned would charge for development of a player for their formats. I'm guessing in many cases the price would be high enough to make a player unlikely, but I don't know for sure.
 
ok, thanks for the information. I'll start converting some files in order to have some ready for the d-day ;)
as for sharing them, I guess it will be *donkey, as it could be nice to get entire movies and episodes for a quite light weight. better not DL 700 meg if it's for watching it as a converted 100 meg file..
anyway, thanks for info.
 
Hi guys, MPG1 will take up generally about 640MB of data for a fairly short movie (74 min if a remember the white book spec). And the data is spooled at single CD speed 150k a second. I think your standard SM databus can read data in the several MB per second region. This is for an off the shelf MPEG1 VideoCD. Stats would obviously vary for a superCD. Standard resolution was 352x240 I think. So would could spool it ok, but would need a bigger SMC, and the quality would be below divX, but with a better frame rate.
 
didn't think of the cd1x 150k, but true those cards must handle at least that.. It could be nice for demostuff, like videoclips and such, especially as they're often directly in mgp1
