           Summary: Mute when change current-audio at playbin
    Classification: Platform
           Product: GStreamer
           Version: 1.4.0
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---


I have an media file with several audio, video and text streams. I simply play
it with gst_parse_launch(“playbin”, &error);” followed by setting the url.
If I start playing it I got every ms an error message called
“gst_amc_audio_dec_handle_frame: Downstream returned flushing”. I don't know if
this error message is the reason why it is not possible to change the audio
stream. After setting the state to PLAYING everything plays well altough I got
the error messages. If I then switch the audio stream by calling "g_object_set
(player->pipeline, “current-audio”, streamID, NULL);" audio stops after a short
time and the error messages still arrive. If I switch back to stream 0 it
starts playing again.
