HandbrakeCLI command lines

Question

I'm trying to convert DVD iso files to mp4 using HandbrakeCLI. I use the following line in a batch file:

D:\HandBrakeCLI.exe -i "D:\input.iso" -o "D:\output.mp4" --no-markers --width "720" --height "480" --preset "HQ 480p30 Surround" --encoder "mpeg2" --audio-lang-list "eng"   

When I do this, I must then extract the audio from the file, using the following line:

D:\eac3to\eac3to.exe "D:\output.mp4" "D:\output.wavs" -down16  

However, when I attempt to extract the audio, I get the error message

The format of the source file could not be detected.

Is there anything wrong with my former line of code that's causing the mp4 to get screwed up?

Minor side question: I'm also trying to get handbrake to remove subtitles and also only keep English audio, do you know what code could be used for that? I started a bit there with the --audio-lang-list "eng" but I'm now sure what to do from there.

Thanks a lot in advance!

Answer 1

You need to use a valid audio format. .wavs is not valid. You have to use an available audio codec to output to the below for --aencoder. The default output audio for MP4 is .aac

av_aac

copy:aac

ac3

copy:ac3

eac3

copy:eac3

copy:truehd

copy:dts

copy:dtshd

mp3

copy:mp3

vorbis

flac16

flac24

copy:flac

opus

copy

Defaults for audio

av_mp4 = av_aac

av_mkv = mp3

You need to pass none for no subtitles

-s none

And define only eng track like you were doing

--audio-lang-list eng

Check out the Handbrake CLI Documentation for the command line code:

https://handbrake.fr/docs/en/latest/cli/cli-guide.html

You can also try using a different program once you extract the audio. A program like XMediaRecode. It can also remux audio and video and convert other audio formats to wav
