Encoding raw video

[Dušan Poizl]

my appsrc creation code

    GstVideoFormat format = gst_video_format_from_masks(24, 32, 4321,
255<<8, 255<<16, 255<<24, 0);
    GstVideoInfo info;
    gst_video_info_init(&info);
    gst_video_info_set_format(&info, format, w, h);
    info.fps_n = framerate.numerator;
    info.fps_d = framerate.denominator;

    GstCaps *caps = gst_video_info_to_caps(&info);
    gst_app_src_set_caps(GST_APP_SRC(appsrc), caps);

    gst_caps_unref(caps);
    g_object_set(appsrc,
                 "stream-type", GST_APP_STREAM_TYPE_STREAM,
                 "format", GST_FORMAT_TIME,
                 "do-timestamp", TRUE,
                 "is-live", TRUE,
                 "min-latency", (gint64)0,
                 "blocksize", info.size, NULL);

also why do you have three videoconvert elements? one is enough. also
remove capsfilter as appsrc will have caps set on their own.
