  GStreamer | gst-plugins-base | Ver: git
           Summary: gdpdepay + identity cause failed assertions
           Product: GStreamer
           Version: git
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: j.urbanski at students.mimuw.edu.pl

     GNOME version: Unspecified
   GNOME milestone: Unspecified


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  0xb7822e7b in gst_base_transform_handle_buffer (trans=0x8418070,
inbuf=0x8428ca0, outbuf=0xb76057b8) at gstbasetransform.c:1268
#7  0xb7823a4c in gst_base_transform_chain (pad=0x83f7640, buffer=0x8428ca0) at
gstbasetransform.c:2018
#8  0xb7f13957 in gst_pad_chain_data_unchecked (pad=0x83f7640, is_buffer=1,
data=0x8428ca0) at gstpad.c:4047
#9  0xb7f14498 in gst_pad_push_data (pad=0x83f7580, is_buffer=1,

#10 0xb78693b2 in gst_gdp_pay_reset_streamheader (this=0x83f7400) at
gstgdppay.c: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
