I use FFmpeg under Windows 7 to stream live video. There are no problems with the camera, but for some reason I can't capture sound from the microphone (I've tested it, it works fine).
I use the -list_devices true
command and my microphone is named Microphone (Realtek High Defini
. But when I set the "audio" parameter to audio="Microphone (Realtek High Defini"
, an error occurs:
[NULL @ 036e2240] Unable to find a suitable output format for 'audio=Microphone
(Realtek High Defini'
audio=Microphone (Realtek High Defini: Invalid argument
Here are full commands I use:
ffmpeg -list_devices true -f dshow -i dummy
and
ffmpeg -f dshow -i video="FaceCam 1320" audio="Microphone (Realtek High Defini" -vcodec h264 -acodec libmp3lame -ac 2 -b:a 128k -ar 44100 -f flv rtmp://localhost/streamApp/cam1

Your input parameter is not right, FFmpeg parses your audio as the output file. Try adding a
:
-sign between your video and audio input.Take a look at the DirectShow FFmpeg wiki for more information about the right parameter settings.
