Re: [Rhythmbox-devel] Gapless/crossfade playback in svn trunk

["Christophe Dehais" <christophe dehais gmail com>]

Hello,

Just tested the new backend, here is some feedback:

* I experience lag (about 1sec) in skip / go back / play / pause actions
* Position slider behavior is not as reliable as in the standard
backend: sometimes it doesn't show the actual position, and when
crossfade is activated the end of the song is hardly reacheable
(because it has jsut skipped to the next song)
* my spectrum analyser plugin doesn't work with it (It listens to
messages on the bus, I'll investigate that)
* the zero-gap
* it crashes when playing mpc files : Rhythmbox-ERROR **: file
rb-player-gst-xfade.c: line 2088 (preroll_stream): assertion failed:
(stream->src_blocked)
aborting...
* the sound is slightly over-saturated.
* gapeless functionnality seems rather solid for what I tested, even with mp3.


cheers,
Christophe
