Description Xavier Queralt 2008-12-23 10:35:34 UTC 
Linking the encoder to the gdppay element produces the following error:

ERROR: from element /GstPipeline:pipeline0/GstGDPPay:gdppay0: The stream is in the wrong format.
Additional debug info:
gstgdppay.c(656): gst_gdp_pay_chain (): /GstPipeline:pipeline0/GstGDPPay:gdppay0:
first received buffer does not have caps set

And this is the used pipeline:

$ gst-launch videotestsrc ! ffmpegcolorspace ! smokeenc ! gdppay ! fakesink

Which works correctly with another encoder like theoraenc.

I've gone through the different commits on that encoder and I think that the regression was introduced on the following commit (reverting it allows the pipeline to work):

Comment 1 Wim Taymans 2008-12-23 12:10:50 UTC 
        * ext/jpeg/gstsmokeenc.c: (gst_smokeenc_init),
        (gst_smokeenc_getcaps), (gst_smokeenc_setcaps),
        (gst_smokeenc_chain), (gst_smokeenc_change_state):
        * ext/jpeg/gstsmokeenc.h:
        Implement getcaps function.
        Set caps on the pad and on all outgoing buffers.
        Fixes #565441.
