Hi All,
I installed Rhythmbox (0.5.3) about 24 hours ago. It did take me a
while to get everything running (mostly some gstreamer issues, I think),
but altogether not too painful. So far I am really impressed and
pleased with what I have seen.
A couple of the problems led me to casually poke around in the code.
Obviously I don't have a good sense yet for what is going on, but I have
a few questions and maybe you can point me in the right direction (or
let me know that I am totally screwed up).
Right now I am using RB on a pretty extensive collection of FLAC files
that I previously ripped with grip.
RB did a great job of tracking down all the files, organizing them, and
labelling them correctly as far as artist/album/title. Very cool.
However, it seems to be identifying all of the files wrong. An example
properties/details output would be like this:
Name: owner_of_a_lonely_heart.flac
Duration: 57:23
Quality: Very low
Encoding: 64 kbpsMPEG 1 Layer III (Mono)
Location: /flac/music/yes/90125
(etc...)
And when I tried to play a song, I got an error message like, "Cannot
find file type" (that's not quite right but close).
I presume that RB is using gstreamer to identify the file type. And, in
fact, gst-typefind was unable to identify the files either.
The flac modules appear to be registered, as gst-inspect | grep flac
returns:
flac: flacenc: FLAC encoder
flac: flacdec: FLAC decoder
flac type: application/x-flac: .flac
Finally, I went poking through gst-plugins-0.6.3 and in gstflac.c I
found the function flac_type_find, which looks like this:
static GstCaps*
flac_type_find (GstBuffer *buf, gpointer private)
{
guint32 head = GUINT32_FROM_BE (*((guint32 *)GST_BUFFER_DATA (buf)));
if (head != 0x664C6143)
return NULL;
return gst_caps_new ("flac_type_find", "application/x-flac", NULL);
}
If I comment out the return NULL, my files are identified as FLAC files
and they play correctly (although the duration and other details still
seem to be messed up). I realize that this brutally ugly little hack
could probably cause ANY file to be identified as FLAC.
Phew - wow - this is a ridiculously long first email, sorry about that.
Anyway, has anyone seen these problems? Is that constant a magic
number? Could it be screwed up? Could all my flac files have gotten
screwed up when I ripped them? And, should I take these questions to
the gstreamer mailing lists?
Thanks in advance.
Fred
