hi folks:
i launch a pipe line with with gstreamer command as below: gst-launch-1.0 filesrc location=/mnt/UDISK/N_1080P_AVC_60F.avi ! avidemux ! h264parse ! omxh264dec ! queue ! waylandsink the target sink i use was "waylandsink" , which take weston wayland server as compositor server. i grab the pipe line graph like follows picture, the waylandsink receive data format with "YV12" format, which can be supported by my soc display hardware, but when i debug the kernel with display register, i can only found one RGB graphic layer was used, not even a single YUV layer was take up. which means there must be someone doing the convertion job from "YV12" to "RGB" fomrat, and compositor the video picture and GUI into one layer. but from the below picture, the only module between the YV12 gstwaylandsink and the display device is the "weston" server, so is the weston is the key to do the convertion job? can i show the yuv picuture directly without convertion? thanks for your help!
