新手求助之二 无法通过avs编码音频

[yabbay]

首先 直接片源拖bat是可以编码音频的
此为bat主要内容
ffmpeg -i "%~1" -f wav - | neroAacEnc -hev2 -q 0.45 -ignorelength -if - -of "%~dpn1_a.m4a"
（然而一用avs无论ffmpeg换dshow2wav还是neroAacEnc换qaac都不行）
此为avs
FFVideoSource("B:\01.mkv",timecodes = "01_v.txt")
LanczosResize(1280,720)
（FFVideoSource换DirectShowSource也不行）
错误信息是

B:\>CD /D "D:\Tools\Playin Packet\AVS\avs\avs\x264\"

D:\Tools\Playin Packet\AVS\avs\avs\x264>ffmpeg -i "B:\01.avs" -f wav - | neroAacEnc -hev2 -q 0.45 -ignorelength
-if - -of "B:\01_a.m4a"

如果将bat改成
ffmpeg -i "%~s1" -acodec pcm_f32le -f wav -vn -ar 48000 - | qaac.exe --tvbr 48 -q 2 --raw-rate 48000 -o "%~dpn1_a.m4a" -

FFVideoSource无音频，DirectShowSource默认不用audio=true也无音频
ffms2可以换FFmpegSource2用atrack=-1加音频（多音轨的要看情况）

顺便我不建议用avs加载处理音频

感谢upyzl大 换FFmpegSource2后ffmpeg和dshow2wav都没问题了
