Has anyone had any luck in getting any of these to work?
I can\'t seem to get it...
Maybe I need simpler instructions... :wink:

Well...21 views, and no answer...maybe I\'m not the only one that\'s having trouble...I feel *slightly* better.
In any event, for those who are curious, I\'ve seen some stuff floating around about a specialized version of mplayer (something about an ATI chip?), with a semi-complicated set of options that have to be set (reversed image?)...If I find out anything, I\'ll let you all know!

Nope I have similar problems - it\'s not just you :wink:

Yaaay!
Nice to know I\'m not (completely) insane!
In other news, I *did* get mplayer to run.
Took a LOT of work, and I think I kind of fumbled around until I got the http://www.self-core.org/~kaoru-k/pub/mpla....91.1-1_arm.ipk (http://www.self-core.org/~kaoru-k/pub/mplayer-w100_0.91.1-1_arm.ipk) to work correctly...I forgot exactly how.
In any event, you\'re left with a player that runs well...as long as you don\'t actually try to do anything with the video, which is rotated the wrong way. Everybody seems to have a page about settin\' this option or that, which kills the frame rate...and I says to myself \"Hey, self: When you\'re recompressing the video so that it\'ll fit on to the memory card, why don\'t you go ahead and rotate it THEN, and when it\'s on the player, it\'ll already be oriented the RIGHT way?\". Problem solved! :-)
You\'re still only gettin\' 320x240, and you don\'t want to get TOO crazy with the bandwidth, but it beats the snot out of what you can do with the WM9-encoder.
(My encoder-of-choice is VirtualDubMod)
Good luck!

Howdy all!
Well, for those of you who are following this thread in hopes of watching stuff on your Z: Good news and bad news.
The good news: There\'s a new media player out there that does a pretty good job of covering up all those nasty mplayer command-line switches, etc. (they\'re still there, if you go to the terminal). It\'s called \"Kino2\" (\"Movie\" in German, and possibly some other languages...get it?), and you can find it at: http://cacko.biz/sl-c7x0.html (http://cacko.biz/sl-c7x0.html)
The bad news: It\'s not the video...it\'s the AUDIO...(!)
Yup: The major driving factor in video playback on our C7X0s is...audio! I\'m trying to see if the various flavors of audio (MP3, MP2, WAV, etc.) can make a difference, but here\'s a fun test:
Try encoding your favorite video to 320x240ish, at ~200kbps. (<- Notice, no audio!)
Even at 24/5 fps, you should get most of your frames without having to skip that much (using -framedrop), of course, YMMV.
Now, go ahead and re-encode at ~100kbps, and add a teeeeny little 16khz, 16kbps MP3 stream.
Ok, math time! We went from ~200kbps, now down to ~116kbps. No problem, right?
WRONG!!! Using -hardframedrop (-framedrop won\'t even come CLOSE to keeping up)...and maybe -autosync 1, you will see....a whole lotta smearing. :-(
(If you just use -framedrop, you\'ll see...not much, then agonizingly slow frame updates.)
Soooo....I think we\'re just waiting for someone to re-encode for the ATI chipset (W-100?) *AND* add in OGG support...and maybe we\'ll actually have a functional movie player!!
So, I leave you for now...Until that great day when I can watch the Matrix at 640x426 (down from 720x480), 25fps, 192kbps OGG... ;-)

-Or not.
I just found a very nice encoding of the first few minutes of Shrek.
Good sound (stereo!), nice video...
???
Maybe it\'s an issue of coding for the C7X0s native hardware (so that it doesn\'t have to do any filtering/resampling)?? Maybe that\'s what I did wrong...by using a mono stream at (possibly) the \"wrong\" khz, instead of lessening the workload, it increased it?
Hmmmm....

Yup, wierd as it may seem, it\'s better to encode a \"harder\" stream (at 48khz), than to throw the Z a \"softball\" (11/16khz). I was able to encode and get good playback off of a 320x240x25fps stream, with 48khz/128kbps stereo. Occasionally it stutters, but it quickly catches up (talkin\' about Kino2 here). Some people have talked about lowering down the frame rate to 12, etc. but I just can\'t bring myself to that...maybe I\'ll lower the bitrate on the video some. I\'ve tried to encode at ]320x240, specifically at 640x4XX (c\'mon, admit it! You were thinking the same thing!), but it doesn\'t seem to work through Kino2\'s interface. Going to the terminal left me with a nice, smooth...resized image. ;-)
In any event, I think that pushing that many pixels would take a lot of work, so we\'re probably going to have to wait for some major revisions to mplayer\'s ATI W-100 code (also, adding in OGG support) before we can even think of that...
