Resolution modification in decoder

[ramakrishnakama]

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.

Video property of the video we are using for testing is as follows :

Topology:

Properties:

Duration: 0:01:53.791000000

Tags:

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

Hi Ramakrishna kamath,

       I got the video clip and the detail description, from the description, your engineer  meet two width/height values for the video size, both of them are not the correct width/height, the demux return value only indicate that the container size setting, this value could be incorrect, the 384x304, 1920x1088 is also not the video size, it 's only used to allocate bigger memory for vpu,  you should use the VUP decoder returned value for your counting.

Hi Jack,

Vpudec doesn't support WMV1 and WMV2.

How can we get resolution values from DECODER?

Please help us to fix this issue.

Thanks and Regards,

Ramakrishna Kamath.

Hi Ramakrishna Kamath,

      For ms decoder I don't know if you use our decoder or open source decoder , if it's our decoder, there is decoder header file, init API will parser the sequence header and return thr resolution value. If you use open source, you have to find it by yourself.
