what's the result of 'RGBX'?
RGB is not fourcc

Comment 2 Ouping Zhang 2013-06-19 02:56:46 UTC

cmd:
gst-launch-0.10 filesrc location=/home/gst_AVC_conformance/Mux_Stream/H264_640x368_frame300.MP4 ! qtdemux ! vaapidecode ! vaapipostproc ! video/x-surface,type=vaapi,format=\(fourcc\)RGBX ! vaapisink

It can work, but when using "vaapidownload ! video/x-raw-yuv,format='(fourcc)'RGBX ! filesink location=HW.yuv", it failed with error:
 ERROR           GST_PIPELINE ./grammar.y:614:gst_parse_perform_link: could not link vaapidownload0 to filesink0

vaapidownload support RGBx

we can build pipeline like this:
gst-launch-0.10 filesrc location=/xxx.MP4 ! qtdemux ! vaapidecode ! vaapidownload ! video/x-raw-rgb ! filesink location=HW.yuv

Comment 4 Zhong Cong 2013-06-25 08:48:07 UTC

ok,the bug is fixed in commit 3e7aa4a9/branch 0.4

Comment 5 Yang Lianyue 2013-06-25 09:05:13 UTC

step:
gst-launch-0.10 filesrc location=/xxx.MP4 ! qtdemux ! vaapidecode ! vaapidownload ! video/x-raw-rgb ! filesink location=HW.yuv
mplayer HW.yuv -demuxer rawvideo -rawvideo w=640:h=368:format=rgba -fps 5

Test OK. Issue can't be reproduced. Close it.
