Issue with decodebin element

Hi,

When I try to decode an mpeg interlaced elementary stream with the following
pipeline

gst-launch-1.0 -v filesrc location=/mnt/hgfs/d/test/libav/carrace.m2v !
decodebin ! filesink location=/mnt/hgfs/d/test/libav/carrace.yuv

I get following error
*/GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstTypeFindElement:typefind.GstPad:src:
caps = video/x-h263
Missing element: H.263 decoder*

Not sure why typefind is finding this as an H263 stream

Interestingly, the following pipeline works perfectly

gst-launch-1.0 -v filesrc location=/mnt/hgfs/d/test/libav/carrace.m2v !
mpegvideoparse ! avdec_mpeg2video ! filesink
location=/mnt/hgfs/d/test/libav/carrace.yuv

Is there a genuine issue here?

~BO
