Hi,

I've been using vlc 1.0.6 goldeneye.
It works fine.

I used this to install it on my fedora machine.
$> su -
#> rpm -ivh http://download1.rpmfusion.org/free/fed ... noarch.rpm
#> yum install vlc

it worked fine and things were going on smooth.

I then downloaded the vlc 1.1.0 source code and tried to install it on the same machine.

Ever since then, ive had issues with vlc and the transcoding pipeline i've used in the past.

vlc -vvv v4l2:///dev/video0:input=0:width=176:height=144:adev=hw.1,0:samplerate=32000 --sout=#'transcode{vcodec=mp4v,acodec=mp4a,venc=ffmpeg{keyint=40,vt=20},vb=800,ab=16}:rtp{mp4a-latm,dst=182.172.255.25,port-audio=45192,port-video=45194,sdp="file://n19.sdp"}'

It yields a

[0x7f8720001b88] avcodec encoder error: cannot open encoder
[0x7f8720001b88] main encoder error: Streaming / Transcoding failed
[0x7f8720001b88] main encoder error: VLC could not open the encoder.
[0x7f8720001b88] main encoder warning: no encoder module matching "ffmpeg" could be loaded
[0x7f8720001b88] main encoder debug: TIMER module_need() : 3.595 ms - Total 3.595 ms / 1 intvls (Avg 3.595 ms)
[0x7f8728001c98] stream_out_transcode stream out error: cannot find video encoder (module:ffmpeg fourcc:mp4v)
[0x7f8720000c28] main decoder debug: removing module "rawvideo"
[0x7f8728001c98] stream_out_transcode stream out error: cannot create video chain
[0x7f872800fd08] main packetizer error: cannot create packetizer output (I420)

Now this is alarming because initially i thought it was because it was some linux conflict, but i downloaded the vlc windows version and it showed the same error there.

cannot open encoder.

I tried to deal with this by downloading various encoders for mpeg4 ( k-lite pack and 3ivx etc) but the problem still persists.

What seems to be the problem?
Does anyone know why vlc acts like this?

What do you have before?
