Command Line Transcoding, No Audio

Posted: 20 Aug 2013 18:51

This command line transcode works, except there is no audio in the result. Looks like it is missing the encoder??? I posted the part of the log file that seemed relevant, but let me know if you need to see more.

Windows 8 and running VLC 2.0.8 (Aug 16 build)

Thoughts?

Thanks in advance!
Chad

P.S. It seems like the source is already in mp4 format so in this case, is it possible to tell it to use the audio stream as-is with out transcoding it to the same format?

Code: Select all

vlc -I dummy -vvv --logfile="C:\VLC_Log.txt" --extraintf logger --stop-time=30 "%srcfilepath%" --sout=#transcode{vcodec=h264,vb=1024,acodec=mp4a,ab=128,scale=1,channels=2,deinterlace,audio-sync}:std{access=file,mux=ts,dst=%dstfilepath%} vlc://quit

Changing

Code: Select all

acodec=mp4a
To

Code: Select all

acodec=mpga
works. Not sure why mp4a didn't.

I have the same issue.
Windows 8. VLC 2.0.8.
Transcoding to H264 / AAC by command line.
It seems that the AAC encoder is missing.
Is it specific to the 2.0.8 version or is it a (f*) Windows 8 problem ?

I'm having this exact same problem; I have never been able to transcode to mp4a without some kind of difficulty since the update to v2 (this is why I still have v1.1.12, but it has compatibility issues of its own).

I've managed to get it to work sometimes by going into VLC's preferences, choosing show all/advanced and going into video codecs > ffmpeg, and setting strict standards compliance to -2. I'm not sure how you would do this with the command line but there must be an option somewhere, though setting it via the GUI may be good enough. But this only solves the problem for some files, not all, even though as far as I can tell all the files I've been trying to process are identical.

The ones that give me trouble are usually ones with AC3 audio (which I try to transcode out since AC3 audio codecs on OS X are a pain in the ass), but if I transcode only the video the audio won't be passed through as normal, it will simply be missing. I don't know why this happens, but it means that instead of having a nice folder of widely compatible .mp4 files I instead have a mix of files that worked and ones I had to copy at full-size because I can't seem to do anything with them, very annoying.
