</span>Yes, this works well enough without zerocopy encoding/decoding. I<br>
haven't used nvvidconv and don't have a TX1.<br>
<br>
If you need zerocopy between the decoder and upstream libgstgl, you'll<br>
need to patch gst-omx to know about libgstgl. Fortunately, I have<br>
already created some branches for that purpose that work with GStreamer 1.8:<br>
<a href="https://github.com/ystreet/gst-omx-nvidia/" rel="noreferrer" target="_blank">https://github.com/ystreet/gst-omx-nvidia/</a><br>
<a href="https://github.com/ystreet/gst-plugins-bad/tree/nvidia-1.8" rel="noreferrer" target="_blank">https://github.com/ystreet/gst-plugins-bad/tree/nvidia-1.8</a><br>
<br>
The next GStreamer release (1.10) changes this slightly to more<br>
performant implementation of the EGLImage memory. I'm not aware of any<br>
branch that deals with that yet. From 1.10 onwards, something like<br>
<a href="https://cgit.freedesktop.org/gstreamer/gst-omx/commit/?id=27d2cdd45dcf0bbd58c753e4b33058607153c4c1" rel="noreferrer" target="_blank">https://cgit.freedesktop.org/gstreamer/gst-omx/commit/?id=27d2cdd45dcf0bbd58c753e4b33058607153c4c1</a><br>
would need to happen in nvidia's fork of gst-omx or someone would need<br>
to forward port nvidia's gst-omx to upstream gst-omx.<br>
<br>
Hope that helps<br>
