Hi,
I met some movies(like *.mkv and *.avi files) which include multi audio tracks and then my application can not switch audio when playback.
I tried to just unlink the demuxer and the audio decoder and then called gst-element-get-pad() to get another audio pad which will be linked to the audio decoder that is able to decode the audio. But I can not hear anything. The code looks like following
GstPad *src_pad, *sink_pad, *demux_src;
FAIL_CHECK (NULL == (demux_src = gst_element_get_pad(demuxer,"audio_01")));//Get anotherdemuxer source pad
FAIL_CHECK (NULL == (sink_pad = gst_element_get_pad(a_decoder, "sink")));// Get audio decoder sink pad
src_pad = gst_pad_get_peer(sink_pad);//get the audio pad connected to decoder sink pad
gst_element_set_state(player_status->bin, GST_STATE_PAUSED);
gst_pad_unlink (src_pad, sink_pad);
gst_pad_link(demux_src, sink_pad);
gst_object_unref(src_pad);
gst_object_unref(sink_pad);
gst_object_unref(demux_src);
gst_element_set_state(player_status->bin, GST_STATE_PLAYING);
//End
It seems that does not work well. Does anyone have the idea about this?
Thanks a lot
