The VideoLAN Forums

For a while I've been using VLC 1.1.11 to transcode videos to MPEG2. After updating to VLC 2.0 I get the following error:

[0161d420] stream_out_transcode stream out error: cannot find audio encoder (module:any fourcc:mp2a). Take a look few lines earlier to see possible reason.
[0161d420] stream_out_transcode stream out error: cannot create audio chain
[020c8b80] main decoder error: cannot create packetizer output (mpga)

The command line to transcode I am using is the following:

"C:\Program Files\VideoLAN\VLC\vlc.exe" --sout "#transcode{vcodec=mp2v,fps=30,vb=7000,acodec=mp2a,ab=224,samplerate=48000,channels=2,deinterlace}:std{access=file,mux=ps,dst="output.mpg"}" --sout-transcode-width 720 --sout-transcode-height 480 "C:\Movies\big_buck_bunny_1080p_stereo.avi" "vlc://quit"

Is there a new codec for MPEG2 audio? Has the option changed? i tried changing the transcode to use 'mpga' instead of 'mp2a' but that only encodes to MPEG1 audio and I need MPEG2.
Thanks for any help on this.

Do you have the twolame plugin in your plugins window?

Thanks for the prompt response.

A search of the Plugin Window shows the following plugin:

Libtwolame audio encoder

mpeg 1 audio and mpeg2 audio are the same

mpga gives layer 3 while mp2a gives layer 2.

Thank you for the clarification. I need layer 2, mp2a...however I get the error I described above whenever I attempt to transcode to mp2a. It doesn't matter what type of source file I use.

should I not be using 'acodec=mp2a' in the transcode command line? The 'acodec=mp2a' worked fine in version 1.1.11 of VLC.

mp2a in 1.1.11 created layer3, you know ?
Anyway, file a bugreport and I will fix.

Wow, that's confusing.

I will file a report. Thanks for the help!

Report filed.

Ticket #6227 (for those who might want to check up on it and/or add more information)

I only have the capability to test on the windows platform. If anyone else can try this on other platforms and update the ticket that would be appreciated.

Thanks.

After some research and much hair pulling in version 1.1.11 I have found that mp2a created mpeg audio version 1 layer 2 and mpga creates mpeg audio version 1 layer 3.

pff... ok

I wanted to let you know that I recently made a rather large (for me anyway) donation to the project in the hope of increasing the priority on the resolution of this issue. Since the product is free you programmers deserve some reward.

Yes, I saw it and I am working on it.

Awesome. Thank you very much.

Fixed for 2.0.2
