Description Jan Urbański 2009-05-26 09:09:58 UTC
With the following pipelines (and latest git):

  gst-launch audiotestsrc ! vorbisenc ! oggmux ! gdppay ! identity ! fakesink
  gst-launch videotestsrc ! theoraenc ! oggmux ! gdppay ! identity ! fakesink

I get lots of errors like that:

  gst_caps_is_subset: assertion `subset != NULL' failed
  gst_caps_is_fixed: assertion `GST_IS_CAPS (caps)' failed
  identity0: could not get in_size

After running with --gst-fatal-warnings the following backtrace can be obtained from the core:

(...)
  • #6 gst_base_transform_handle_buffer
    at gstbasetransform.c line 1268
  • #7 gst_base_transform_chain
    at gstbasetransform.c line 2018
  • #8 gst_pad_chain_data_unchecked
    at gstpad.c line 4047
  • #9 gst_pad_push_data
    at gstpad.c line 4277
  • #10 gst_gdp_pay_reset_streamheader
    at gstgdppay.c line 491

However, none of these pipelines gives any errors:

  gst-launch audiotestsrc ! vorbisenc ! oggmux ! gdppay ! identity
  gst-launch audiotestsrc ! vorbisenc ! oggmux ! gdppay ! fakesink
  gst-launch audiotestsrc ! vorbisenc ! oggmux ! gdppay ! gdpdepay ! identity ! fakesink

    gdppay: set caps on outgoing buffers
    
    Set caps on outgoing buffers because NULL caps confuse basetransform.
    Fixes #583867
