[求助]請問AAC編碼的音頻可以分離出來嗎？
請問AAC編碼的音頻可以分離出來，把他轉成AC3的格式後然後再跟視訊部分合成一個新的TS檔嗎！
因為最近下了九寨溝風光 完整版4片裝的，他的音頻是AAC的編碼，可是我的多媒體播放器
不支援，之前下的九寨溝珍藏是濃縮版的，他的音效好像是對岸的同胞重新合成的是LPCM
格式的，我想仿效他的方式，不知有哪位前輩能指導在下，感謝！ GraphEdit應該可以做到:

AAC -> AC3 Fast GraphEdit/ffdshow way:
Fast method with ffdshow:
get GraphEdit from: http://www.3ivx.com/download/windows.html look for the link to GraphEdit in the upper right corner.
get new FFDSHOW from: http://www.aziendeassociate.it/cd.asp?dir=/ffdshow download newest version of ffdshow
-install ffdshow
-activate decoding for aac!
-extract graphedit in a folder
-start graphedit
-drag&drop AAC-file in GraphEdit window
-click and remove "default direct sound device"
- click Menu graph->insert new filter->DirectShowFilter->Filewriter and "insert filter", choose filename "convert.ac3"
-right click on ffdshow->properties->output->AC3 and "allow direct-to-file output" and "don't use Waveformatextensible"
-click ok
-connect ffdshow filter with the file writer "convert.ac3" filter
-click play to start conversion and wait until its finished
If your output stutters it is very likely that your sampling rate is 44KHz and not 48KHz Some soundcard don't output 44KHz over S/PDIF correctly. To solve this, activate the resampler in ffdshow and set it to "Resample if sampling rate below... 48000Hz".
