To summarize :

With :
gst-launch-1.0 playbin uri=file:///tmp/bug743687.mkv

Playback is failing to display any picture.
The negotiated pipeline is sending I420 buffers to the sink, but buffers are
flagged with meta:GstVideoGLTextureUploadMeta. This is not a supported
configuration reported by the sink.

With :
gst-launch-1.0 filesrc location=bug743687.mkv ! matroskademux ! h264parse !
vaapidecode ! clutterautovideosink

Playback is working well.
The negotiated pipeline is sending RGBA buffers to the sink, buffers are
flagged with meta:GstVideoGLTextureUploadMeta.

It seems something is going wrong when playbin is involved.
