Can anyone tell me why it is failing ? ) </div> </blockquote> How do you know the issue is "vaapidecode is unable to connect with vaapiencode_h264" ?? Does it working with vaapisink? I tried couple of local media files (decode + re-encode + flv mux) in my HSW machine, can't reproduce the issue... Anyway, move the discussion to gstreamer mailing list OR file a bug against gstreamer-vaapi in gnome-bugzilla if your pipeline is working with "vaapidecode + software_encoder(x264enc)" but not with "vaapidecode + vaapiencode"... Please run the pipeline with GST_DEBUG=vaapi*:4 to get a bit more debug log... <blockquote cite="mid:CADTobL33t=Gf8SbW8sQ6CgQe5nk05Ne1SWqW11j_A_7d=xmCdg@mail.gmail.com" type="cite"> <div dir="ltr"> <pre>GST_DEBUG=3 gst-launch-1.0 flvmux name=mux streamable=true ! rtmpsink sync=true location=<a class="moz-txt-link-rfc2396E" href="rtmp://xxxxxxx">"rtmp://xxxxxxx"</a> rtspsrc location="<a class="moz-txt-link-freetext" href="rtsp://">rtsp://</a><a moz-do-not-send="true" href="http://admin:admin@192.168.0.162:554/cam/realmonitor?channel=1&subtype=0" target="_blank">admin:admin@192.168.0.162:554/cam/realmonitor?channel=1&subtype=0</a>" ! rtph264depay ! queue ! h264parse ! vaapidecode ! queue ! vaapiencode_h264 rate-control=cbr tune=high-compression ! mux. libva info: VA-API version 0.38.0 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so libva info: Found init function __vaDriverInit_0_38 libva info: va_openDriver() returns 0 Setting pipeline to PAUSED ...
