The OMX specification have issues related to interoperability and missing a lot of features for modern hardware. Khronos no working on it anymore, and Raspberry Pi having completely moved away from it, we believed it was time to get rid of it and use our precious resources on APIs that do have a future. It worth mentioning that Google Android is also moving away from that, though GStreamer OMX have never supported Android extensions.</div><div><br></div><div>Nicolas</div><div><br></div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><div><br></div><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Aug 5, 2023 at 8:08 AM Nicolas Dufresne via gstreamer-devel <<a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a>> wrote:<br></div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><div class="msg7476167257250253184"><div><div>Hi,</div><div><br></div><div>Le samedi 05 août 2023 à 15:00 +0800, Hau Lam via gstreamer-devel a écrit :</div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><div dir="ltr">Hi Gstreamer dev team, <div>I'm exploring omxh265enc plugin and saw that it has control-rate property </div><div><span style="color:rgb(0,0,0);font-family:SFMono-Regular,Menlo,Monaco,Consolas,"Liberation Mono","Courier New",Courier,monospace;font-size:12px;white-space:pre-wrap">control-rate : Bitrate control method
