[gst-devel] distorted video encoded with x264

[Rafael Sousa]

Hi all,

I'm using the versions of gstreamer installed from ubuntu 10.10 apt-get.
I've installed the gstreamer, gst-plugins-bad, gst-plugins-good,
gst-plugins-ugly, gst-ffmpeg and I've installed the x264.

The problem is that my pipeline gives as result a blurring video. My
pipeline works to read a YUV file at the sender, encodes it in H.264, and
sends it to receiver using RTP in encoding time. At the receiver, it
receives the stream and stores it in YUV format again for posterior process.
The pipeline is as follows:

Sender:

"gstrtpbin name=rtpbin filesrc location=paris_cif.yuv blocksize=152064
! video/x-raw-yuv, width=352, height=288, framerate=(fraction)15/1,
format=(fourcc)I420 ! x264enc, key-int-max=30, key-int-min=15,
intra-refresh=true ! rtph264pay
! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! udpsink host=127.0.0.1
port=5000 rtpbin.send_rtcp_src_0 ! udpsink host=5003 port=5001 sync=false
async=false udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0 "

Receiver:

"gstrtpbin name=rtpbin udpsrc
caps=\"application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264"
port=5000
! rtpbin.recv_rtp_sink_0 rtpbin. ! rtph264depay ! ffdec_h264 ! filesink
location=example.yuv udpsrc port=5001 !
rtpbin.recv_rtcp_sink_0 rtpbin.send_rtcp_src_0 ! udpsink port=5005
sync=false async=false"

I don't know why the video is blurring since I've tested it localhost,
without loss rates. The command that I'm using to watch the result is:

mplayer example.yuv -demuxer rawvideo -rawvideo cif

I took a screenshot of the video, it is in annex. Please, anyone can help?

thanks in advance
