            Bug ID: 783991
           Summary: openslessink: Unable to use native sample rate(48000)
                    for low latency audio playback on most Android devices
    Classification: Platform
           Product: GStreamer
           Version: 1.x
                OS: other
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---

To obtain the lowest output latency on android (~20 ms), you must supply audio
data that matches the device's optimal sample rate and buffer size. Otherwise
output latency is 100 - 200 ms, which for some projects is a big deal.
openslessink should be able to accept all provided sample rates (including
48000 Hz) and have a parameter for setting optimal buffer size.
