[Bug 748259] [PATCH] New audio/video level element

[GStreamer (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=748259

--- Comment #10 from Stefan Sauer (gstreamer, gtkdoc dev) <ensonic at sonicpulse.de> ---
More ideas.

1) What about changing this element into one called 'audiosync' /
'audioadapter' / ... . The element would get video and audio ins and it would
push all audio into an GstAdapter and foreach videoframe push the matching
audio.
On the 'level' and 'spectrum' elements, we can add a flag to send a
message-per-buffer, since now the buffers perfectly cover a frame. We should
probably add a new property for this (and not use a special value like interval
== 0), not sure what others think.

2) Another option could be to make the 'interval' property controlable and to
have a 'videorate-controller' element that exports a control-source that emits
the video rate. Not sure if we can pigy-back that feature into an existing
element that one would use anyway (encoder baseclass?).
