Hello All,
I am using gst-omapfb plugin built from openembedded which
contains X-overlay patch on normal omapfb plugin as my video sink. My normal
pipeline is as followed.
$gst-launch-0.10 filesrc location=1.mp4 ! myparser ! mydecoder ! omapfbsink.
Src pad of my decoder is set as following caps .
("video/x-raw-yuv",
"width", G_TYPE_INT, mpeg4dec->info.width,
"height", G_TYPE_INT, mpeg4dec->info.height,
"framerate", GST_TYPE_FRACTION, mpeg4dec->fps_nu, mpeg4dec->fps_de,
"format", GST_TYPE_FOURCC, GST_MAKE_FOURCC ('I', '4', '2', '0'),
"pixel-aspect-ratio", GST_TYPE_FRACTION,1,1,i NULL);
Omapfbsink will accept I420 format and convert it to UYVY
format and copy it to frame buffer. In these all process it is using memcpy
which copy data from buffer pushed from my decoder to buffer allocated
locally. Here in omapfbsink memcpy is time consuming. Instead of using
memcpy I would like to use some other method. But I am getting how can I
replace memcpy.
If anyone can guide me to replace memcpy, I will be pleasure
for me.
-Tejas.
