I understand what you're saying. Perhaps you could shed some light on the next questions: Preamble: PVR350 in a Shuttle S51 (Celeron 1.8G). mplayer with the ivtv patch. Not using x11. mplayer -vo ivtv works not too bad... if the video stream is not ac3 (and thus not using -ac hwac3) I get far worse jerkiness/tearing. I am assuming this is because mplayer is converting from divx or mpeg4 or whatever I'm playing and mpegpes (and spitting that out to the card to decode and display) -- is this a good assumption? Obviously mplayering an .mpeg I created with the card is perfect, as is dd'ing the file directly to /dev/video16. ivtv-fb doesn't seem to initialize correctly on my system -- the framebuffer is "skewed" and if I use -vo ivtvfb I can see that it's playing to the framebuffer, but it's not viewable due to the skew. I havne't spent gobs of time trying to get the fb output to be correct, and I'm not sure I even know how to go about it. The output seems to be quite a bit smoother though, and I'm guessing it's because mplayer is spitting framebuffer data to the card instead of trying to recode to mpeg2... is this correct? I'm using ALSA for output since it appears to be the only sane way to get the digital output to work with this system. If I use OSS it seems to mute the digital out, even if I had turned it on. I had no idea that sound would cause so much trouble and additional processor load. :-) -A. -A. > > if you want it to play back generic video smoothly, > then help the folks who are working on YUV decoding. > That is your only hope. > > -tmk > > > ------------------------------------------------------- > This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting > Tool for open source databases.
