No sound on windows 8 #11

Closed matinlotfali closed 10 years ago

matinlotfali commented 10 years ago

Hi, I wrote an application that uses ffmpeg and dshow. windows 7 captures the sound of output but on windows 8 64bit it is silence.

here is my code: ffmpeg.exe -f dshow -y -i video="screen-capture-recorder":audio="virtual-audio-capturer":audio="Microphone (USB Audio Device)" -framerate 15 -vcodec libx264 -crf 0 -preset ultrafast -acodec pcm_s16le -vf crop=Width:Height:Left:Top output.flv

I also installed MSVC 2010 and registered the dlls. What should i do?

Are you playing something that generates audio in the background?

If not does something like this help? http://blogs.msdn.com/b/matthew_van_eerde/archive/2008/12/10/sample-playing-silence-via-wasapi-event-driven-pull-mode.aspx On Sun, Aug 24, 2014 at 6:53 AM, Matin Lotfaliee notifications@github.com wrote:

My problem is fixed by registering DLL after installing vcredist. Using nsis installer, registeration failed without notification.
