thanks, now with i420 is better, however there are still some performance
regressions with other formats, for example:
git master:
gst-launch-1.0 videotestsrc num-buffers=2000 !
video/x-raw,width=1920,height=1080,format=YUY2 ! videoscale !
video/x-raw,width=320,height=240 ! fakesink sync=false
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Got EOS from element "pipeline0".
Execution ended after 0:00:09.526237997
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ...
1.4:
gst-launch-1.0 videotestsrc num-buffers=2000 !
video/x-raw,width=1920,height=1080,format=YUY2 ! videoscale !
video/x-raw,width=320,height=240 ! fakesink sync=false
Impostazione della pipeline a PAUSED ...
La pipeline è in PREROLLING ...
La pipeline è in PREROLLED ...
Impostazione della pipeline a PLAYING ...
New clock: GstSystemClock
Ottenuto EOS dall'elemento «pipeline0».
Execution ended after 0:00:07.107416794
Impostazione della pipeline a PAUSED ...
Impostazione della pipeline a READY ...
Impostazione della pipeline a NULL ...
Esecuzione di free sulla pipeline...
