why no sound after capture video?

Hey Dedy,

You have ALSA commented out, which is correct if your on Windows..

Now you need to :

  • make sure the ip camera really is streaming audio & video
  • determine the format - is it being packaged with the mpeg4 video? - is it a seperate stream? - what format is it? Ogg? or some other format?
  • change your transcode appropriately - here are some examples with audio - http://www.videolan.org/doc/videolan-howto/en/ch09.html

post a video or at least a picture of what your doing so far....

 

do you think I should change the line :
 
acodec = mpg into acodec = mpga

Sure, I think you've made great progress - but now, you know more about your system than I do.  
So, you will have to experiment and try to find the correct codec - documentation regarding your IPCamera should say something about it.

Good Luck

Hi, first of all, thanks for this amazing post! Currently im trying to only "see what my webcam sees". So i'm not considering the //Save Video part. When i run the code, it just shows a black window, no image. My webcam doesnt respond either (no "active green light").

What would you suggest?

Thanks in advance!

PS: im running this on Eclipse, Windows 7, the webcam is a Microsoft LifeCam VX-800. And all, besides Windows, is running in a x86 basis.
