Internal data flow error during caps modification

[hrbaty]

Hi.

I have a simple pipeline like this:
											/|queue2|--|edgetv|--|ffmpegcolorspace|--|appsink|
|v4l2src|--|videoscale|--|capsfilter|--|ffmpegcolorspace|--|tee|
											\|queue2|--|xvimagesink|

The capsfilter element looks like this:
    caps = gst_caps_new_simple("video/x-raw-yuv",
                               "width", G_TYPE_INT, m_high,
                               "height", G_TYPE_INT, m_width,
                               "depth", G_TYPE_INT, 24,
                               "bpp", G_TYPE_INT, 32,
                               "framerate", GST_TYPE_FRACTION, 10, 1,
                               NULL);
g_object_set(G_OBJECT(capsfilter), "caps", caps, NULL);

and everything works fine, but I'd like to modify caps before appsink.
So I decided to add next caps filter between |ffmpegcolorspace|and|appsink|
    caps_2 = gst_caps_new_simple("video/x-raw-rgb",
                               "width", G_TYPE_INT, m_high,
                               "height", G_TYPE_INT, m_width,
                               "depth", G_TYPE_INT, 8,
                               "bpp", G_TYPE_INT, 8,
                               "framerate", GST_TYPE_FRACTION, 10, 1,
                               NULL);
g_object_set(G_OBJECT(capsfilter2), "caps", caps_2, NULL);

But now I get internal data flow error. What do I do wrong here? Or maybe
there is another way to set caps in appsink, without capsfilter?

Thanks for any hints.

BR
