Audio-CD burning-software has problems with gstreamer

[Keywan Tonekaboni]

I got this error from gnomebaker:

Internal GStreamer error: pad problem. File a bug.gstpad.c(2562): gst_pad_set_explicit_caps: /gnomebaker-convert-to-wav-pipeline/decoder/mad18:
failed to negotiate (try_set_caps with "audio/x-raw-int, endianness=(int)4321, signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)44100, channels=(int)2" returned REFUSED)Internal GStreamer error: negotiation problem. File a bug.gstmad.c(1213): gst_mad_check_caps_reset: /gnomebaker-convert-to-wav-pipeline/decoder/mad18:

serpentine has the same problem:

GError: could not link audioscale0 to wavenc0

A friend of me sent me detailed information, that the gstreamer pipeline didn't work, but I dont have his IM-Message here.

I reported this bug also for gstreamer0.8, but their was no reaction.

This bug is a showstopper, because audio burning is a must-feature.

Sebastian, do you have an idea on that?

Having the pipeline giving you that error would be nice

[Sebastian Dröge (slomo)]

gnomebaker uses gst0.8, serpentine gst0.10...

other than that it would help to get a test file for reproducing it... can you upload one somewhere?

[Keywan Tonekaboni (prometoys)]

I test it with different files. It's a generell Problem, but you can try it with ogg's from endererror:

The pipeline is described in the bug report for serpentine:

That could be nice if people could get a clear bug with a command tried with gst0.10

[Alexandre Otto Strube (surak)]

Hello Sebastien. I read both bug #22501 and bug #30684 - and according with Keywan, this still happens with gstreamer 0.10. So both those bugs can be marked as duplicates from this one (because they have so much information about this one).

[Sebastien Bacher (seb128)]

They have been marked as duplicate of bug #22501
