Hi, I'm using command  gst-launch-0.10 playbin uri=file:///home/prafull/downloads/sample_iPod.m4v Here I'm using omx_audio sink and omx_video sink for playing audio and video. Here I'm able to render audio data but not video data. Here I'm getting warning gstomx_base_videodec.c:settings_changed_cb (gst-launch-0.10:7956): GStreamer-WARNING **: pad omxh264dec0:src returned caps which are not a real subset of its template caps   (gst-launch-0.10:7672): GStreamer-WARNING **: pad omxh264dec0:src returned caps which are not a real subset of its template caps (gst-launch-0.10:7672): GStreamer-WARNING **: pad omxh264dec0:src returned caps which are not a real subset of its template caps gstomx_base_sink.c:handle_event Pipeline is PREROLLED ...

"video/x-raw-yuv,format=(fourcc)UYVY,width=640,height=480,framerate=24/1" > ! omx_videosink Actually I observed that maximum range of framerate in gstomx_base_video_decoder.c src Template is 30/1 but by setting_changed return value is more than this range that's why it is not able to negotiate caps. Where I should change to make caps negotiation proper between  decoder and sink component.
