Hey,
This reminds me of the fact that that in clutter-gst-video-texture.h
there is "GstElement *clutter_gst_video_texture_get_playbin
(ClutterGstVideoTexture *texture);", but there's nothing regarding that
clutter-gst-video-texture.c. Should there be?
Attached is a change I did when I tried using the function in the header
file and found it not implemented. Feel free to apply it.
I was just indeed experimenting a bit with audio visualization, using
the playbin something like this:
audiosink = gst_bin_get_by_name(GST_BIN(playbin), "audio-sink");
sink_pad = gst_element_get_pad(audiosink, "sink");
gst_pad_add_buffer_probe(sink_pad, G_CALLBACK(audio_cb), self);
Then you can eg. calculate visualizations in the callback function from
the data.
