When we play video using mfw_wmvdecoder, video resolution getting changed.

Actual video resolution is 320 X 240. But decoder output resolution is 384 X 304.

Because of this setting video property not proper and video not getting played in

middle of the screen.


gst-lauch-0.10 filesrc location=/mnt/usb/320x240_WMV7_WMA7.asf typefind=true !

aiurdemux name=demux demux. ! queue ! mfw_wmvdecoder ! mfw_v4lsink -v


We can see change in resolution of in output of deocder.

Seekable: yes


container format: ASF

video codec: Microsoft Windows Media 7

audio codec: WMA Version 7


We are using gst-fsl-plugins version 3.5.7 and gstreamer version 10.36

Linux freescale 3.0.35-2154-g94689e1 #180 SMP PREEMPT Wed Mar 4 15:24:49
