<div>   Well, Now I'm focusing on the avi file play pipeline. Here I'm trying this command line: gst-launch -v filesrc location=/convert.avi ! avidemux name=demux demux.video_00 ! mpeg2dec ! ffmpegcolorspace ! video/x-raw-rgb,bpp=32,depth=32,width=128,height=112,framerate=25/1,endianness=4321,pixel-aspect-ratio=1/1,red_mask=65280, green_mask=16711680, blue_mask=-16777216, alpha_mask=255 ! dfbvideosink And of course I get the format not negotiate err.

I'm digging the code and it's a real disaster to me :( OK, some answers for stefan: 1.And your sure that the dfbvideosink works. What does "gst-inspect dfbvideosink" prints? Of course the dfbvideosink works, since i can get the test application "dfb-example" which only generate a simple pipeline between videotestsrc and dfbvideosink work on the board, and even now I can get the raw video data play correctly on the target. 2. probably the audio inside the avi? Yes,now I use the mpeg2dec instead of decodebin, so nothing to do with the auido things.i'm also facing some problems in audio playback. So make them work separately first. 3. I was just curious what device your working on. Er,,, some kind of picture frame things, can view picture, play video, play mp3 etc..
