Webcam + ffmpeg on Windows problem (i can pay if you help me)

[GordonFreeman]

Hi all,
i'm in trouble with screencasting from a virtual camera and the sound card to ffmpeg on Windows.
I'm trying to achieve this capturing both of them with VLC, and then pass the stream to ffmpeg.

I'd want to ask you some support , and i'll pay for this, it's not a matter.

Specifically, the problem is this:

i have Magic Camera, and i need to capture its output along with the sound card output, and send them to ffmpeg via a pipe.

I tried this command, but VLC says it can't open the video encoder (audio works):


"C:\Documents and Settings\VMWARE\Desktop\VLCPortable 1.0.5\App\vlc\vlc.exe"
dshow:// :dshow-vdev="MagicCamera Capture(User Mode)" :dshow-adev="Creative Sound Blaster PCI"
--sout #transcode{vcodec=mp4v,vb=3800,scale=1,
acodec=mp3,ab=128,channels=2,samplerate=44100}:std {access=file,mux=ts,dst=-} | ffmpeg -i - -f flv -b 550k
-s 384x288 -ar 44100 -ab 64k -ac 2 -y rtmp://192.168.1.68/live/livestream

the same command works if i replace this:

dshow:// :dshow-vdev="MagicCamera Capture(User Mode)" :dshow-adev="Creative Sound Blaster PCI"

with a file on disk, or an internet live video stream ( http://123.123.123.123/stream-path )

Furtherly, if i simply play the (virtual)webcam, vlc shows it correctly.

I tried to specify different encoding parameters for vlc, but in that case ffmpeg can't recognize the format, or gives me other errors.
for example i've tried specifying
vcodec=theo acodec=vorb mux=ogg

If you have a solution, let me know and give me an estimate for the price please.
You can also replace the virtual webcam with another one, and replace VLC with other capture software, but the stream must be redirected to ffmpeg.

thank you in advance
