[gst-devel] Problem with a pipeline: Internal data flow error/Internal data stream error

[Rohit Atri]

It's a problem with caps your specifying for your required conversion.

gst_base_transform_acceptcaps:<capsfilter0>
*transform could not transform *video/x-raw-yuv, format=(fourcc)I420,
width=(int)720, height=(int)576, pixel-aspect-ratio=(fraction)16/15,
framerate=(fraction)25/1, interlaced=(boolean)false* in **anything we
support*
*
*
check what is expected and what your supplying and make sure they match.
