Crossfade

[Neil Loknath]

I've seen rumours that there will be crossfade functionality in playbin2.  Any truth to that?

I see that there is an old bug report here where someone created some plugins for various cool things, crossfading included.  But, I guess they failed to port the code to new versions.

http://bugzilla.gnome.org/show_bug.cgi?id=307012

Specifically, I'm interested in crossfading and pitch control.  So, if any work is being done on either of these, it would be great if someone could point out where to read about it.

Thanks,
Neil

I don't know about the plans for playbin2, but some basic crossfading
support is already in rhythmbox[1] and pitching can be done with
soundtouch[2].

so long

Thanks for the links, buz.
I had already known about rhythmbox, but the soundtouch is something I will have to check out soon.  To elaborate on my initial question, I wanted to know if playbin2 was going to provide crossfader support because of some rumors that it will be providing gapless playback support.  However, I'm not sure if it is actually going to be implemented or if its just that the about-to-finish signal is there to help others develop it into their programs??

If crossfading is going to be available in GStreamer in the near future, there might not be much point in working on it myself.  Same goes for gapless.

Thanks,
Neil

playbin2 already supports gapless playback fully. It does not do
crossfading; I don't know of any plans to make it do so.
