I'm especially wondering what ports are used in that case and > how they're connected. It's pretty trivial to support, it's only a property to set on the encoder node itself. I'm not really sure what you meant by your question with the ports though :/ Maxime --ocew46sopze2pn2e Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRcEzekXsqa64kGDp7j7w1vZxhRxQUCXkbARQAKCRDj7w1vZxhR xWgZAQCoX6IPh3nfofCSZf7uxIEwmYH/acb4D64t70G8fNoW4AEA0scufZoOcED6 nd6GkciRxgxAXhF3LhkXYBnzHA7tnQY= =1YtU -----END PGP SIGNATURE----- --ocew46sopze2pn2e-- --===============1441934860== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel --===============1441934860==--
