</div> You don't need a typefind in your pipeline. It fails to find the type of the<br>
raw video (there's nothing in a raw video stream to indicate what type it is)<br>
and therefore it doesn't negotiate its caps with the pngenc.<br>
<br>
To debug a pipeline, it's convenient to strip it down until something works,<br>
that way you can find out which element causes the problem. You can replace<br>
a video source with videotestsrc and the sink with fakesink. That way,<br>
you'll find out that<br>
<br>
videotestsrc ! typefind ! pngenc snapshot=false ! fakesink<br>
<br>
doesn't work, while<br>
<br>
videotestsrc ! pngenc snapshot=false ! fakesink<br>
<br>
does work.<br>
