appsrc and caps

Hi everyone,

Just a short update concerning my issue ( I am still stuck on it).

I tried to be more specific for the different capabilities inside the
pipeline (add caps before and/or  after ffmpegcolorspace, specify masks and
endianness) : 

m_gstreamerData.pipeline = gst_parse_launch("appsrc name=mysource !
video/x-raw-rgb, width=748, height=480, framerate=30/1, red_mask=16711680,
green_mask=65280, blue_mask=255, endianness=4321 ! ffmpegcolorspace !
video/x-raw-yuv, format=\(fourcc\)UYVY, width=748, height=480 !
xvimagesink", NULL);

It still doesn't work but the debug output is not the same : 

0:00:01.067705313  3867      0x2765de0 INFO           basetransform

imgconvert.c:3736:img_convert: no direct path to convert colorspace from
rgb24 -> yuv422p
Segmentation fault (core dumped)

I have not other warning or errors, and these messages appear when I push
the buffer in the appsrc.

Any idea ?
