Video orientation change

[bojan74]

As I wrote I solved the webm problem with rotating video (from portrait to
landscape) last time with setting bigger dimensions using capsfilter (width,
height).

But now I get a case where it looks there is some other change in caps than
just dimensions.
If I compare two caps looks like that:
video/x-raw, format=(string)I420, width=(int)360, height=(int)640,
interlace-mode=(string)progressive, multiview-mode=(string)mono,
multiview-flags=(GstVideoMultiviewFlagsSet)0:ffffffff:/right-view-first/left-flipped/left-flopped/right-flipped/right-flopped/half-aspect/mixed-mono,
pixel-aspect-ratio=(fraction)1/1, chroma-site=(string)mpeg2,
colorimetry=(string)bt709, framerate=(fraction)0/1

video/x-raw, format=(string)I420, width=(int)270, height=(int)480,
interlace-mode=(string)progressive, multiview-mode=(string)mono,
multiview-flags=(GstVideoMultiviewFlagsSet)0:ffffffff:/right-view-first/left-flipped/left-flopped/right-flipped/right-flopped/half-aspect/mixed-mono,
pixel-aspect-ratio=(fraction)1/1, chroma-site=(string)jpeg,
colorimetry=(string)bt601, framerate=(fraction)0/1

So beside height and width, there is also change in colorimetry and
chroma-site.

That's why I tried to fix also these two parameters inside capsfilter:
video/x-raw, width=1000, height=1000, chroma-site=(string)jpeg,
colorimetry=(string)bt601

But now I get this error:

My pipeline in this test was:
appsrc->rtpjitterbuffer->rtpvp8depay->vp8dec0->videomixer->capsfilter->videoconverter->vp8enc->webmux



Do I need to set some other caps too to be able to negotiate?

But if I don't add these two parameters chroma-site=(string)jpeg,
colorimetry=(string)bt601 there is no problem with negotiations but I got
error:
matroska-mux.c:975:gst_matroska_mux_video_pad_setcaps:<webmmux0> error: Caps
changes are not supported by Matroska


So how to fix caps for webm but anyway to be negotiated?
