video rescaling

[Patrick Welche]

Given a sample video, e.g., http://techslides.com/demos/sample-videos/small.ogv
and following the videoscale documentation,

gst-launch-1.0 -e \
filesrc location=small.ogv ! decodebin ! video/x-raw ! videoconvert \
! videoscale ! video/x-raw,width=50 ! ximagesink

does exactly what one expects. If I channel the output to a file

gst-launch-1.0 -e \
filesrc location=small.ogv ! decodebin ! video/x-raw ! videoconvert \
! videoscale ! video/x-raw,width=50 ! x264enc ! filesink location=out.mp4

the file has the desired resolution, but gst-play-1.0 out.mp4 displays a 
window of the original dimensions.

What am I missing?


Cheers,

Patrick
