Command line WAV -> AAC not working anymore

[LuxZg]

Hi everyone,

I'm newbish when VLC command line is in question. But I have used it successfully for a while with earlier versions (1.0.3 for example) to encode WAV file to AAC file through the batch script. I've upgraded VLC few times since last using the script, including latest 1.1.0 yesterday, and now script isn't working anymore.

Here is the old script:

Code: Select all

vlc -vw "E:\path\aaa.wav" --sout=#transcode{acodec=mp4a}:standard{access=file,mux=mp4,dst="E:\path\aaa.aac"} vlc://quit

I've tried the "vlc -vvv" instead of -vw but I still can't get working AAC file (I get a 0kb or 1kb file that won't play, of course).
I've also read in the dev log that access_file was obliterated, in favor of filesystem. But I couldn't find any sample or help that would lead me to solution how to fix this.

I hope someone more experienced can shed some light on this. Thanks!

Try with "mux=ffmpeg{mux=mp4}" instead of just "mux=mp4".

Like this?

Code: Select all

vlc -vw "E:\path\aaa.wav" --sout=#transcode{acodec=mp4a}:standard{access=file,mux=ffmpeg{mux=mp4},dst="E:\path\aaa.aac"} vlc://quit

..or...

Code: Select all

vlc -vvv "E:\path\aaa.wav" --sout=#transcode{acodec=mp4a}:standard{access=file,mux=ffmpeg{mux=mp4},dst="E:\path\aaa.aac"} vlc://quit

With first one I get error pop-up (command line pop-up of sorts):
The command line options couldn't be loaded, check that they are valid.

With second one I get zero-byte aac file that is useless.

Any other suggestions?

what are the logs?

Um, just let me see where are the logs first, and I'll get back to you in a few minutes

EDIT:
OK, if using -vw switch, I always get that same "The command line options couldn't be loaded, check that they are valid." error, so that can't be used.

If I use -vvv, and muxing either in the "old" way or as Lotesdelere suggested, I get this error:

Code: Select all

Streaming / Transcoding failed: VLC could not open the encoder.

So it's not the script, but encoder not loading.. But if I open VLC manually, go to Media, than Convert/Save, Add the same wav file, go to Convert/Save->Convert, set destination, and pick an "Audio - AAC (MP4)" preset, and Start - I get the file that I can play.

Btw, for some reason I couldn't get the proper log file to be created, and I've set the option in the Preferences, even tried creating empty txt file manually and setting the permissions, starting as Admin etc. So this is error copied from the "pop-up" window (which I probably never saw because I had "vlc://quit" at the end of my script )

Bump.

Anyone? Am I calling the wrong encoder in the command line? Since encoder obviously works (if done through GUI)..

You need to post whole -vvv output, not just the parts that says 'error'

Well, I'd be glad to, but command prompt gives out no errors at all, and I can't get the log file running.. :/ Any way to get the output in the command prompt? Seems I'll just have to troubleshoot this myself when I get more time, or go back to earlier version for now.. :/
