[求助] 制作mkv时用aac声音出现问题
SoMaster@2006-06-02 23:51
这个警告我是第一次见的, 也不知应该怎办才好
首先不明白我如何分辨aac是否含有HE-AAC / AAC+ / SBR AAC audio ?
还有到specifiy 选择 aac-is-sbr 0 又是什么意思呢?
打开MMG看了很多遍也找不到 specifiy 啊!
然后这是完整的log

mkvmerge v1.6.5 ('Watcher Of The Skies') built on Dec 7 2005 18:53:31
'H:\1.avi': Using the AVI demultiplexer. Opening file. This may take some time depending on the file's size.
'H:\2.aac': Using the AAC demultiplexer.
'H:\3.ass': Using the SSA/ASS subtitle reader.
'H:\4.ass': Using the SSA/ASS subtitle reader.
'H:\1.avi' track 0: Using the video output module.
Warning: AAC files may contain HE-AAC / AAC+ / SBR AAC audio. This can NOT be detected automatically. Therefore you have to specifiy '--aac-is-sbr 0' manually for this input file if the file actually contains SBR AAC. The file will be muxed in the WRONG way otherwise. Also read mkvmerge's documentation.

AAC is SBR/AAC+
有类似这样的选项的
是否sbr就要问你了，因为aac是raw格式，是否sbr不明

LC AAC和AAC通常顯示44.1(CD轉的)或48K HZ(DVD聲音)
HE AAC 是2XK HZ 這種的要在MMG裡把SBR打勾才會正常
96K HZ的DVD音軌如果是LPCM儲存目前我只想到轉WMA 10去壓縮
