Distorted audio capture on Vista
 
|
I have been experimenting with audio capture on Windows. I use the
following command line: gst-launch-0.10 dshowaudiosrc num-buffers=400 ! audioconvert ! audioresample ! faac ! mp4mux ! filesink location=test.mp4 I tested this on two Vista laptops using the built-in mic and in both cases the recorded audio was too fast and "crack"-distortions can be heard. On my Macbook Pro running Windows 7 the recording is perfect. The Vista machines are capable of recording good quality audio when using the Acer webcam software tool. I suspect that the issue is with the dshowaudiosrc component because I can also reproduce the problem using other codecs. Does anyone have an idea how things are going wrong? Or better, how to fix it :) Grts, Francis PS: I use the latest WinBuilds GStreamer distribution. ------------------------------------------------------------------------------ The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |

Update:
directshowaudiosrc works fine on my PC at home that has Windows XP. I modified some the ossbuild code so that the directsound plugin also contains the directsoundsrc element: gst-launch-0.10 directsoundsrc num-buffers=300 ! audioconvert ! audioresample ! faac ! ffmux_mp4 ! filesink location=test.mp4 It works fine on my Windows XP machine at home. I'll try it on the Vista laptops Monday. Grts, Francis 2010/2/5 Francis Rammeloo <[hidden email]>: > I have been experimenting with audio capture on Windows.

If this one works better it should have a higher rank than dshoeaudiosrc to be electable by autoaudiosrc.
