Encoding audio by ffmpeg

[xunix 0]

Hi Guys .

 

I have problem, couldn't encode audio with video at the same time by using ffmpeg

 

This my avs script ( I tried both of them )

 

V=  FFvideoSource("Detective_Conan.mkv")
A = FFAudioSource("Detective_Conan.mka") 
AudioDub(V,A)
trim(0,400)

 

FFmpegSource2("Detective_Conan.mp4",atrack=-1)  
trim(0,400)

 

and this's  the command line 

 

avs2yuv 842.avs - | ffmpeg -y -i -  -c:v libx264 -c:a aac -b:a 128  output_.mp4

 

the result is video without audio.

While I love AviSynth for a lot of things, it looks like an operation that would be more easily done with just ffmpeg.  You're passing the output to ffmpeg anyway and it's just remuxing to add an audio stream.  Specifying the video and audio files as inputs, then using the appropriate -map options should work just fine. 

 

That being said, do either of the scripts play properly (with audio), out of curiosity?  Also, I don't think avs2yuv handles audio, as it was intended to be used with video-only encoders like x264.  ffmpeg should be able to take avs files as inputs (at least on Windows it does), so you can try that as well.
