           Summary: h264parse parse data error when AVC head only 2 bytes
    Classification: Platform
           Product: GStreamer
           Version: 0.11.x
        OS/Version: All
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: gst-plugins-bad

use this cmd pipeline:

kulou1.mp4 is a video from youtube, and can not be played, so I download it for
checking.

gst-launch filesrc location=/workspace/avdata/kulou1.mp4 num-buffers=1000 !
qtdemux ! h264parse ! capsfilter caps=" video/x-h264,
stream-format=(string)byte-stream"  ! filesink location=./mykulou.h264
--gst-debug=*264*:5 -v


0.11 verison is not ok. Otherwisse 0.10 version works good.

And I checked the H264 file dumped by 0.10 version, and I find that the AVC
header is only two bytes. But the verison 0.11 treated it as 4 bytes, so it
will parse out error data.

The attachment is the mp4 file , h264 data dumped by 0.11 gstreamer, h264 data
dumped by 0.10 gstreamer
