Ah, yes of course. Sorry I was a bit fast with giving my rb on
that, should have thought about it more.<br>
<br>
The problem is that the VCE engine can only handle progressive
frames and not the interlaced memory layout.<br>
<br>
What we should do is implementing interlaced -> progressive
conversion in the omx state tracker tunneling handling when that
happens. Then set interlaced to false in the template and
reallocate the video buffer for the next trancoding round.<br>
<br>
The weave filter from the compositor could be used for
interlaced -> progressive conversion. And btw: We are going
to have the same problem with the VA-API state tracker.<br>
</div>
</blockquote>
<br>
Just concern this may cause performance compromised. How about we
add a environment variable at the same time to false the interlaced,
so that it's up to user to choose either way.<br>
<br>

Leo<br>

<div>Hi Leo,<br>
<br>
</div>
Sorry for the inconvenience, could you let
me know how to reproduce the problem ?<br>
</div>
I have been playing with some gst pipelines
and they all work but I can only test with
nouveau driver.<br>
<br>
</div>
Cheers<br>
