从字幕组下的mplayerc6458_chs_w2kxp放不了mkv的魔法留学生8
没声音，画面有是有，但停止不动的。
比如拉到0：15时会显示0：15时的画面，拉到3：10会显示3：10的画面
是不是还需要另外插件的？？

安装wma的decoder和realmedia splitter.......

@ skywalker
Wah?! real audio/video + wma/wmv ?!
This is really a weire mixture.
I can understand:
RV9 is good
WMV9 is good
but RA and WMA is'nt really that nice. What is the point of using so?
Also specification of musing RV9 into mastroka is'nt fix yet, it is not wise to use RV9 in mkv now, as later mkv filter might well be incompatible with current RV9-MKV
skywalker@2003-07-23 04:45
I see your point, but I didn't do it.....
Because that new rv9 ehq psnr thread, many people are convinced that rv9 is the best format and many ppl also thinks that wma is the best audio format. Thus, why not mixing them together......
Personnally, I still think rv9 is worse than xvid or other codecs at high motion, somehow its two-pass algorithm isn't very efficient at distributing the bits............
Regardless of the possible imcompebility issue, since there is an avi version, so there is nothing to worry about..........
dillee1@2003-07-24 00:18
Hm.... I havnt see many people ppl supporting WMA yet. People prefer to turn to OGG than WMA.
By the way, has popgo got any interest in using AAC or AAC+ ??
I have try AAC+, it rocks. 64kbps AAC+ sounds the same as CBR 128kbps mp3. Really a nice way to punch down the overall birate and file size.
skywalker@2003-07-24 03:38
Since AVI will still be the primary format for releasing animes....
I don't think AAC will be the primary focus.....
besides........
the precieved audio quality is very subjective.........
and it varies with the equiptment used.......
in order to convince ppl AAC is very good........
we need to have some solid evidence(such as conducting a blind test with people here) or some good written essays that explain the advantages of AAC+.........
I dout how many people actually know what's AAC.........
personally, I've heard AAC 5.1........
I think it's very decent...........
dillee1@2003-07-24 12:24
Actually blind test with AAC/AAC+ Vs OGG WMA MP3 has been done recently by hydrogenaudio.
Generally AAC+ score the highest at very low bitrate. Coding Technology decribes AAC+ as tranparent at 64k, although I do find it is more comparable to 128k cbr mp3 than really "transparent".
For the purpose of anime encoding, VBR AAC+ at 50-70k is enough to be transparent. Ogg need ~100k to have similar quailty.
With mkv container now muxing AAC/AAC+ with other video codec is possible, no longer restricted to mp4 and mpeg4 video. It really worth a trial IMO.:p
I do have some AAC+ sample encoded from CD. I can send you and let you judge the quailty yourself.

曾在某動漫站點看到有解釋說.mkv是種過渡性的視頻產物﹐具體沒什麼懂。
skywalker@2003-07-25 22:04
dillee1, what do u use to encode AAC+.......
I used the encoder from nero6.....
when I use the 50K-70K he aac preset........
the quality is much worse than wma......
or maybe i'm using the wrong decoder that dosen't do SBC......

I guess you are not using Nero Waveedit to play back the encoded AAC+ mp4 file.
Currently only Nero Waveedit is capabable of decoding the SBR part properly. Real Player, Quicktime 6, evivo, mp4player and 3ivx none of them are currently able to understand SBR.
Without SBR, high fequency is not reproduced and the reproduced sound is very dull and distorted.
Beside Nero Waveedit, Nero Showtime do provides dshow filter for AAC+ playback. However it always crash on Win 2003 platform.
May be you can try out Showtime and tell me your results. :D
Ahead will release the SBR decoder code under GPL on 25 this month, probably we will see a new version of CoreAAC decoder with SBR support at the end of month then.
skywalker@2003-07-26 05:51
I tried it with wave edit........
now it sounds much better..........
I can hardly tell the difference between the CD and the 60K AAC file with my audio setup........
but I am no where near audiophile.........
the 64k wma I did is slightly duller than aac at low frequency......
I guess 64k of aac is pretty good for anime encoding........
however......
i only tried it with music.......
I will tried with an actual DVDrip see how it does........
too bad the nero encoders doesn't take in ac3 directly.........
I have to transcode it into wav first........
dillee1@2003-07-31 02:28
Finally nero has released SBR code into FAAD.
Now a directshow decoder for AAC+ is available. (Can playback video with aac+ sound in any media player now)
Anyone interested to get a copy?
skywalker@2003-07-31 03:18
Sure......
I would like a copy......
isn't coreaac also coming out soon?
dillee1@2003-07-31 17:38
This is the current/working built of coreaac with SBR.

3ivx d4.1 media splitter + fdshow + AAC+ works like a charm:)
