We noticed that the latest git version of vaapi/gstreamer-vaapi still mentions the vaapiupload/download elements in the readme and that the source files are still present, but they do not seem to be part of the build. We have gstreamer-0.10 installed as well, but the gstreamer-vaapi is a much older version (0.3.6). We tried your suggested pipeline and it resulted in a SIGSEGV.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Our current options seem to be to try to build gstreamer-vaapi with vaapiupload/download included against gstreamer-1.0 and resolved any issues that arise, or to revert to gstreamer-0.10 and update the gstreamer-vaapi to the latest available. Our preference would be to stick with gstreamer-1.0. From reading several posts on this list and in bug reports it seems like the vaapipostproc element would be the place where the colorspace conversion would be supported, but maybe it is not quite ready yet.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Can someone advise if this seems like a reasonable path?
