           Summary: [h264parse] Regression: Assertions on valid h264
                    streams
    Classification: Platform
           Product: GStreamer
           Version: 0.10.13
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: slomo at circular-chaos.org
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


gst-launch-0.10 videotestsrc ! x264enc ! h264parse !
"video/x-h264,stream-format=avc,alignment=nal" ! fakesink

Leads to assertions and the pipeline never prerolls:
** (gst-launch-0.10:12258): CRITICAL **: gst_byte_reader_masked_scan_uint32:
assertion `(guint64) offset + size <= reader->size - reader->byte' failed

Using h264parse to convert the same from a h264 stream inside an MP4 file
additionally gives this assertion:
ERROR:gsth264parse.c:551:gst_h264_parse_check_valid_frame: assertion failed:
(prev_sc_pos >= 0)
Aborted
