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

AssignedTo: gstreamer-bugs at lists.freedesktop.org

GNOME version: ---
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
