Hi, I have written a mail few days to the gstreamer mailing list(not the embedded one...)(see: http://sourceforge.net/mailarchive/message.php?msg_name=4B90C30D.5000101%40atmel.com) ago about a display problem using gstreamer. I still cannot play properly the video when doing: gst-launch filesrc location= mnt/video/AVI/MPEG4/Seinfel d_timestamp.avi ! avidemux name=demux demux.video_00 ! queue ! x170 output=RGB16 inbuf-thresh=0000 output_width=480 output_height=240 ! ximagesink display=:0.0 while it is ok when doing: gst-launch filesrc location= mnt/video/AVI/MPEG4/Seinfel d_timestamp.avi ! avidemux name=demux demux.video_00 ! queue ! x170 output=RGB16 inbuf-thresh=0000 output_width=480 output_height=240 ! fbdevsink Anyway I have another question. My video decoder is also able to crop/scale/rotate/convert colors, and I would like to know what is the best way to use such capabilities within gstreamer? Should I write only one plugin which will do everything or several plugins like for instance one for the decoder, one for the post processing(crop, rotation..) and one for the color conversion? Regards, Sedji
