Hi sharief,

this happen because gst-launch draw directly on FB if you don't have a high level window manager (i.e.. KDE).

If you want to play it correctly, the only way is create a simple application, that use gstreamer and X window.

have you already installed a Xfbdev and xterm packages? if not, please install them.

If yes,after the boot run startx (it will run the windows manager Xfbdev) and open, into the window, a xterm session; Here, you can run a application that use X functions to play gstreamer video.

About application to play media using gstreamer library, and about to play it into a window, look at these websites:

yes thank you. I didnt have this "Xfbdev" package even in freescale website. I have this xterm package. Now my question is whether i have to build new file system enabling this packages in configuration? or shall i load dynamically? and even i didnt have "xvideosink" in my gst-inspect. My another question is how to make this video into fullscreen?it is playing in small portion of my monitor. Please help me. Thanks a lot "morini".

Check on the X packages of ltib system build and you can find Xfbdev. Without it isn't possible to have a Window where "attach" the video to play.

this is the list of gstreamer's Freescale plugins that you have on your system if you add the package into the ltib build:

mfw_vpudecoder: mfw_vpudecoder: Freescale: Hardware (VPU) Decoder
mfw_downmixer: mfw_downmixer: Freescale Audio Down Mixer
mfw_aacplusdecoder: mfw_aacplusdecoder: Freescale AAC Decoder Plugin
mfw_deinterlacer: mfw_deinterlacer: Mfw De-interlace
mfw_wma8encoder: mfw_wma8encoder: freescale wma8 encoder
mfw_audio_pp: mfw_audio_pp: Freescale Audio Post-process Filter
mfw_vpuencoder: mfw_vpuencoder: Freescale: Hardware (VPU) Encoder
mfw_aacdecoder: mfw_aacdecoder: Freescale AAC Decoder Plugin
mfw_v4lsink: mfw_v4lsink: Freescale: v4l_sink
mfw_v4lsrc: mfw_v4lsrc: Freescale Video Source plug-in
mfw_avidemuxer: mfw_avidemuxer: FSL Avi Demuxer
mfw_mp3encoder: mfw_mp3encoder: freescale mp3 encoder
mfw_mpg2demuxer: mfw_mpg2demuxer: Freescale MPEG demuxer
mfw_mp4demuxer: mfw_mp4demuxer: Freescale-Mp4 demuxer plugin
mfw_wma10decoder: mfw_wma10decoder: Freescale's wma10 decoder
mfw_asfdemuxer: mfw_asfdemuxer: FSL Asf Demuxer
mfw_mp3decoder: mfw_mp3decoder: freescale mp3 decoder

the samples that i send to you must be changed, because you have to use Freescale mfw_* plugin, and not the standard one (ie. mfw_v4lsink and not xvideosink).

try the "playbin" way, because it's easy to implement.

To have a fullscreen window, you must create a X window of the same size of the desktop and "attach", with the command "gst_x_overlay_set_xwindow_id, the gstreamer video on it.

You have to learn how gstreamer and X Windows worksto create your application.

Hello morini, I attached x elements in ltib and i compiled again. By that i got this errors

checking for XORG... configure: error: Package requirements (xorg-server >= 1.0.99.901 xproto fontsproto ) were not met:

No package 'xorg-server' found
No package 'xproto' found
No package 'fontsproto' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables XORG_CFLAGS
and XORG_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
