[gst-devel] audio choppy issue while recording ogg theora file

[sudarshan bisht]

Hi Axel ,

           Your log showing that there is some performance issue  when you
record audio/video both ,  as it is dropping the audio samples , and due to
those dropped samples you are listening that choppy sound or no sound at all
.

             Try recording video at lower resolution (176x144) , this may
make things better .
