Does not work ith Helix Xing encoder

[GoogleCodeExporter]

Hi, your nice extension is perfect for my needs. I was looking for something 
exactly like it. In 
particular, I need a tool that uses the profile from 
gnome-audio-profiles-properties. This is 
because I want to use the Helix MP3 encoder. And I added a profile with a 
pipeline using xingenc 
as the encoder, which is the Helix encoder. It is much faster than Lame and the 
quality is similar.

I want to use it to load music onto a small mp3 player for the road, my library 
is all FLAC. Lame 
just takes too long for on-the-fly encoding.

Here's the but, or the bug(?):

nautilus:10731): GStreamer-WARNING **: Failed to load plugin 
'/usr/lib/gstreamer-0.10/
libgstxingenc.so': /usr/lib/gstreamer-0.10/libgstxingenc.so: undefined symbol: 
__gst_debug_min
0:00:08.269431829 10731  0x8d393e8 ERROR         GST_PIPELINE ./
grammar.y:571:_gst_parse_yyparse: no element "xingenc"

I can use this profile form within sound-juicer, but not with 
nautilus-sound-converter. 

If you'd like to confirm, the encoder is a quick compile. Get the source here:

Hadn't heard of that encoder, but I'll give it look.  Also, could you provide 
me with
the pipeline that you added to gnome-audio-profiles-properties for the helix mp3
encoder? Thanks!

Hey, great!

My pipeline is 

   audio/x-raw-int,rate=44100,channels=2 ! xingenc bitrate=128

at the moment. I’m not sure whether a "! id3v2mux" is needed at the end. I 
didn’t get that far.

In case you are interested, here’s a recent listening test. I was very 
surprising. From the look of it, the Helix 
encoder is at least not largely defective and should do it for on the road 
listening. 90× real time encoding 
speed is much better than Lame after all.

Most likely you should have the 'id3v2mux' element in your pipeline, since it 
adds an
ID3v2 header to the beginning of MP3 files using taglib.

I looked into this a bit the other night, and I'm probably going to need to 
read the
source for the gnome-media audio profile widget to get a better understanding 
of how
it is getting the list of gstreamer plugins available.  Currently, when I 
create a
new audio profile for the xing plugin, n-s-c doesn't recognise the new profile.

Is there a possibility that "you" link to gstreamer in some sort of deprecated 
way? I asked on #gstreamer and 
#banshee about this, and the most informed guess seemed to be that "gstreamer" 
is not dynamically linked 
correctly.

One more datapoint may be that Banshee, the player which hosts this codec, can 
also use the Helix/Xing 
element for transcoding and ripping. (Unfortunately it will only transcode onto 
a portable device, not to just 
any destination folder). But as far as I can tell it does not use the 
gnome-media profiles but a custom profile 
system.

I don't really don't think it's due to the linking, otherwise the more 
traditional
plugins wouldn't be working also.   Right now it's looking like a problem is
occurring when gnome-media is being initialized.

In the meantime, I would suggest using the lame plugin and use the bitrate 
option,
and not the vbr option.  Based on my informal tests, this is almost as quick as 
the
gst-xing plugin.

Closing, and re-opening on the GNOME infrastructure.
