Hello, Brian!
Hi Nick,
If you use /dev/radeon_vid then you can be sure that BES is used.
Yeah? OK. I will take your word for it. :-) Maybe I should try some comparisons with and without ":lvo:/dev/radeon_vid" and see if I can see the difference.
Else mplayer will not work and will be terminated with error message.
Okie.
K6-300 is not very powerfull hardware.
No, not by my Athlon TB 800 standards it is not, but I thought it would have done better with Mplayer than 80+%, especially since I am not using the software scaler. Mplayer is using 80+% to simply read the AVI, (de)mux it and ship the data off to the video device to have it do BES and play the audio. My Athlon TB 800 plays the same file on Xv, unscaled (I am assuming because the Radeon does scaling this is a fair comparison) in less than 8% CPU. Is there really that much difference between a K6-300 and an Athlon-800?
Indeed to have successful speed you need with radeon_dvd driver or similar.
You mean using the MPEG2 decoder on the card? But will that help with an OpenDivX (or even MPEG1) stream?
But ATI hides DVD related info (even for GATOS and X11 developers).
Yeah, I know. I would have avoided ATI due to that if there were a choice in BES, TV-Out capable hardware.
O'k - you've reached maximal video performance.
Good. Still seems a bit jerky in some places. Maybe it's just me. I have not sat down and watched a full program yet. Just sampling.
minor correction: '-fs -zoom' will give correct aspect ratio but will not affect on speed.
OK. Thanx.
Also try play with -vc and -ac options.
Which codec(s) do the best job with: MainAVIHeader.dwFlags: (65552) HAS_INDEX WAS_CAPTUREFILE VIDEO: [DIVX] 320x240 24bpp 29.97 fps 1843.4 kbps (225.0 kbyte/s) [V] filefmt:3 fourcc:0x58564944 size:320x240 fps:29.97 ftime:=0.0334 type files? How about audio codecs for: Detected audio codec: [mp3] drv:1 (MPEG layer-2, layer-3) mp3lib: Processor ID: 580 mp3lib: Using AMD 3dnow! optimized decore. AUDIO: srate=22050 chans=2 bps=2 sfmt=0x10 ratio: 8000->88200 It would seem that Mplayer chose the Detected video codec: [odivx] drv:3 prio:0 (OpenDivX (MPEG-4 v2)) for video. I would hope that is the best one since I left it up to Mplayer to decide. b. -- Brian J. Murrell
