I think I'd try elimintating intervideosink from the equation first,
and directly plug the<br>
output to a display sink to see if the problem goes away. Then I
would check the logs<br>
for potential warnings, with GST_DEBUG=2.<br>

<div dir="ltr">Hello everybody,<br>
<br>
I am struggling a bit with the fact that webrtcbin ->
decodebin and then scaling pipeline is not working as expected.<br>
<br>
I get an incoming Pad (incoming_decodebin_pad)<br>
<br>
video/x-raw, format=(string)I420, width=(int)640,
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<br>
<br>
which works perfectly if I do not scale it<br>

<br>
but if I add videoscale-> capsfilter between it to scale it
to "video/x-raw,width=480,height=320" I just get black frames
(next I added `method=0 add-borders=false`to videoscale same
result!)and not even the right dimension.<br>

Here is my Pipeline for the first attempt without videoscale
which works<br>
<br>

<br>
And the one with videoscale<br>
<br>

<br>
Full pipelines are attached as well.<br>
<br>
One thing to add. Even if I use the working pipeline the
incoming webrtc video goes from videoimage to blackframe back to
videoimage for at least 5 sec on START.<br>
The pipeline with videoscale never shows an image just black
frame.<br>
