在linux 下播1080p mpeg2與windows下播放順暢問題?

[THQ]

在相同硬體下
在windows下用media player classic播放1080p mpeg2很流暢也不用特別作什麼設定就可以播了
但在linux下用smplayer播放卻變慢動作且聲音也不同步
output driver 使用的是xv

[Cheung]

你的顯示卡是那一家的？
cpu 等級？

[THQ]

nvidia GeForce 6600 GT
CPU0: AMD Athlon(tm) 64 Processor 3000+ stepping 02

[Cheung]

顯示卡無法做硬解加速
CPU 等級也不夠力做軟體播放
換一片 Nvidia 9400 系列的顯示卡用 vdpau 播放吧

[訪客]

1080p 「mpeg2」CPU應該夠吧！

[Cruz]

雖也沒甚憑據可以提出來斷定，但我認為這個 case 中的 CPU & 顯卡 應該都夠力，問題應該是出在顯卡 driver 或者系統調校方面

我有印象大概兩年前，曾在 acer NB TM230 那種等級 (該機為 2003 購買，夠老吧？) 跑 Linux 也能播放 HDTV 的影片 ( CPU 是 Celeron 1.7G ... 顯卡似乎是 intel 845G 什麼碗糕的)

而且發問者也說了，在 Windows 能流暢播放。 Linux 在這方面比較容易碰到需要費力調校的難題，不是嗎？先前自用的 AMD Sempron 2800+ 搭配 GF6800 執行 Lenny 使用 nVidia 網站下載的 non-free 驅動程式，沒怎麼費力調校也能順利播放 HDTV

後來改用 NB 而且是該死的 ATi 顯卡，三不五十更新後就會出茶包，真是討厭，若不是限於財力不支，真想把他賣了，換一台使用 nVidia 的 NB

smplayer 應該有選項可以看到播放時的 log
貼上來吧。

不然你開一個 terminal 用指令執行 mplayer 去播放1080p 的影片
然後把 terminal 上的log輸出貼上來。

[jesse.sung]

MPEG2 的話，也可以試看看用 XvMC 放看看。

之前試過用 Duron 1.6G oc 1.9G，加上一張 AGP 的 nVidia 5700 (不知道有沒有記錯型號)，1080 的 MPEG2 用 CPU 解不動，但是用 XvMC 讓顯卡幫忙後就很順暢了。

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
- Try -ao sdl or use the OSS emulation of ALSA.
- Experiment with different values for -autosync, 30 is a good start.
- Slow video output
- Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
- Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
- Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
- Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
- Try -nocache.

如果選XvMC,播放時就沒有畫面了

[claudwu]

8系列以上就可以用VDPAU了!
效果不錯，負擔很大的地方會比較好
而且驅動不用太多設定

[企鵝狂]

你應該要貼前半部的訊息,播放太慢會出現那個錯誤訊息是一定的。
