cant transcode x264 + AAC ffmpeg fixed

[ccastro]

i am trying to stream an analog input, using x264 and AAC codecs, but it fails, i already fix ubuntu's ffmpeg and i can encode files with AAC using ffmpeg, but i cant do that with VLC, any ideas?

using VLC:

$ vlc pvr:///dev/video0 --sout '#transcode{width=320,height=140,venc=x264,vcodec=x264,vb=128,acodec=mp4a,ab=128,channels=2,samplerate=44100}:rtp{dst=192.168.254.251,sdp=http://192.168.254.176:8080/vlc.sdp}' vlc:quit

[00000377] ffmpeg encoder error: cannot find encoder MPEG AAC Audio

using ffmpeg:

$ ffmpeg -i Extremists.m4v -vcodec h264 -acodec aac lala.mp4

thx in advance

Your VLC isn't build against that FFmpeg

[ccastro]

how can i fix it?

[xtophe]

rebuild vlc

[ccastro]

thx, but that wasnt necesary. I was preparing my system to rebuild vlc, and after donwload and install build-deps, it works

[xrd]

I just ran "sudo apt-get build-dep vlc". I quit vlc and then reopened it and when I try to select MP4A as the audio codec it still reports the same issue: "ffmpeg encoder error: Cannot find encoder MPEG AAC Audio." Is there anything else you did to enable this?

I have the same problem (AAC Enabled in FFMPEG but not in VLC)

How can i build vlc against my new FFMPEG?

Sounds like a stripped version of FFMPEG without encoders. This is common in Linux distributions.
