I had a look in th eglglesink code, and I read that the window size inside
this element (when force-aspect-ration=FALSE) is determined by the sink
caps. I was waiting that eglglesink will fill my screen (used without X11).
I know that I can use videoscale to resize the stream to my screen size.
Will this solution cost more CPU ?

Well, why should that be different? eglglessink is in both cases
creating a 200x200 window, so there's no need for adding black borders
in both cases.
If you embed eglglessink into your own window of a different size, this
property should make a difference though.

Hello All,
I am trying to stream a mp4 file over the network using following commands:
At Server:
gst-launch-0.10 -v filesrc location=~/home/jyoti/Videos/conf.mp4 !
qtdemux name=demux demux.audio_00 ! queue ! rtpmp4apay ! udpsink
port=5000 demux.video_00 ! queue ! rtpmp4vpay ! udpsink port=5002
host=10.99.26.73
At Client:
gst-launch-0.10 -v udpsrc uri=udp://10.99.26.73:5000 ! qtdemux
name=demux demux.audio_00 ! queue max-size-buffers=8000
max-size-time=0 max-size-bytes=0 ! faad ! alsasink udpsrc
uri=udp://10.99.26.73:5002 demux.video_00 ! queue! ffdec_h264 !
autovideosink
And the file conf.mp4's codec type is MPEG4-PART-10 (H264 AVC) [the
file contains both audio and video)
I dont see any errors on both side, simply it says pipeline is set to
playing and i dont see any outpu display at client side.
Please correct the commands if they are wrong..
I have also seen
http://cgit.freedesktop.org/gstreamer/gst-plugins-good/tree/gst/rtp/README#n251
But i dint get video caps on applying those commands, so iam trying
above commands.
Please help me as iam new to gstreamer..
Thanks in Advance
Jyoti

Yes, to let it fill your screen you should embed eglglessink in your
application into a fullscreen EGL window.

Have a look at the config-interval option in the pay loader.

Oh. And you need to use the h264 pay loader not the mp4v (part 2).

Hi Stirling,
Thank you for your reply. I am using gstreamer 1.0.4 version. As you
suggested I removed "videobox" and re-run the same experiment, but it didn't
change the results. I am wondering how does encoder component in the
pipeline will affect the decoder buffer?? Can you help to understand this?
Because if I run the same pipeline by just removing the encoder, the results
are perfectly fine. I dont see any issues in the tapped yuv and the filesink
output.
Thanks
JasonP
