Description Ilya Konstantinov 2015-07-31 20:36:01 UTC 
To reproduce:

$ gst-launch-1.0 osxaudiosrc ! identity drop-probability=0.1 ! osxaudiosink
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstAudioSrcClock
WARNING: from element /GstPipeline:pipeline0/GstOsxAudioSrc:osxaudiosrc0: Can't record audio fast enough
Additional debug info:
gstaudiobasesrc.c(866): GstFlowReturn gst_audio_base_src_create(GstBaseSrc *, guint64, guint, GstBuffer **) (): /GstPipeline:pipeline0/GstOsxAudioSrc:osxaudiosrc0:
Dropped 9261 samples. This is most likely because downstream can't keep up and is consuming samples too slowly.
WARNING: from element /GstPipeline:pipeline0/GstOsxAudioSrc:osxaudiosrc0: Can't record audio fast enough

I don't quite understand why osxaudiosrc drops frames when the *sink* is the one that's not receiving all of the frames. This doesn't happen with fakesink or filesink.

Also, it's "solved" by setting "osxaudiosink sync=0".

Ilya, is this still an issue with current GStreamer ?
