RT.我试验过了。我用的转换软件是TOTAL 那个。格式是MP4.
然后640X480,不能达到流畅水平。320X240,可以。
然后电影播放的时候 颜色有层次,不是平滑过渡的,难看。然后人物动作的太快就可以看到块块。而静止的时候就要好多了。这个是转换软件的问题,还是播放解码的问题?
有什么好的可以用的转换软件?
然后究竟怎么设置码率这些,声音这些?
码率会不会影响播放的速度?码率低,是不是耗CPU些。如果码率高是不是耗IO操作些?
怎样设置才是最好的?

要设置超频,640的可以流畅播放。
一般VCD类型的片子都可以播放的很好。

你的问题估计是转换软件的问题,我在verycd上下载的中国经典动画,播放起来一般都没问题。只不过那些影片的大小都不标准,所以只能原影片大小播放。

码率低的片子,观看质量不佳。码率太高,CPU来不及处理。

多少码率,论坛上有帖子,找找看。
没找到特别好的转换软件,转换花时间,就不想弄了。

我网上下的AVI都能直接播放.mpg也可以
wmv有问题

转的话太耗时间,变的跟mp4一样了,没优势

应该码率没跟CPU关系不大。更IO关系大些吧。码率不同,我猜是 图像DCT转换后,量化的精度不同搞的。量化这些应该不太耗CPU的

要转的,我转过一个加菲猫2,转90度,640*360,码率500k,转完大概400兆,放在sd卡上看,流畅的,效果不错,颜色我想是因为本来这块液晶就是64k色的,所以有时候一块一块的。我用的是c1000,cacko 1.23自带的mplayer+kino2。

7500C上看320×240还可以,但总没有发挥出显示屏的优势,看640×480是卡的,看起难受。有什么办法解决吗?
因为用7500C主要用途之一就是看电影,如果这样就太郁闷了。
