Videoscale aspect fill

[Johan Basore]

Hello everyone,

I am using videoscale and filter to resize video.
But I can't aspect fill option, just it resize video with aspect fit.
Here are my videoscale codes.

*************************
GstElement *videoscale1 = gst_element_factory_make("videoscale", "videoscale1");
GstElement *filter1 = gst_element_factory_make("capsfilter", "filter1");

GstElement *filtercaps1 = gst_caps_new_simple("video/x-raw", "width", G_TYPE_INT, 200, "height", G_TYPE_INT, 400, nil);
g_object_set(G_OBJECT (filter1), "caps", filtercaps1, nil);
gst_caps_unref(filtercaps1);
gst_element_link_many(clrspace1, videoscale1, filter1, videomixer, nil);

Hi Johan,

There is a plugin called vodeocrop. Give it a try

To get some info on it type in terminal gst-inspect-1.0 videocrop

Best luck,

Hi Johan, 

I think you could crop the video with videocrop before using videoscale.

Your pipeline would look to something like : videocrop ! videoscale ! capsfilter.

In videocrop you'll have to set top, bottom, right and left properties to the correct values.

In the capsfilter you'll set the final display resolution you want.

You can also try to set pixel-aspect-ratio=(fraction)1/1 in your capsfilter caps.

I set pixel-aspect-ratio to "1/1", but it is scale to fill modes.
I need aspect-fill modes.
Here is the result.
