VideoWall MP4 files gstreamer

[amirulsyahmi]

Hi all

I need to play 4 video files in one screen. After doing some research I find this code

gst-launch -e videomixer name=mix ! ffmpegcolorspace ! xvimagesink \
   videotestsrc pattern=1 ! video/x-raw-yuv, framerate=5/1, width=320, height=180 ! videobox border-alpha=0 top=0 left=0 ! mix. \
   videotestsrc pattern=15 ! video/x-raw-yuv, framerate=5/1, width=320, height=180 ! videobox border-alpha=0 top=0 left=-320 ! mix. \
   videotestsrc pattern=13 ! video/x-raw-yuv, framerate=5/1, width=320, height=180 ! videobox border-alpha=0 top=-180 left=0 ! mix. \
   videotestsrc pattern=0 ! video/x-raw-yuv, framerate=5/1, width=320, height=180 ! videobox border-alpha=0 top=-180 left=-320 ! mix. \
   videotestsrc pattern=3 ! video/x-raw-yuv, framerate=5/1, width=640, height=360 ! mix.

which will display like this



bu then I need it to play mp4 files. and I try this code

gst-launch -e videomixer name=mix ! ffmpegcolorspace ! xvimagesink \
   filesrc location=./Cityscape1Min_720p_mp4.mp4 ! decodebin2 ! videorate ! video/x-raw-yuv, framerate=5/1, width=320, height=180 ! videobox border-alpha=0 top=0 left=0 ! mix. \
   filesrc location=./Cityscape1Min_720p_mp4.mp4 ! decodebin2 ! videorate ! video/x-raw-yuv, framerate=5/1, width=320, height=180 ! videobox border-alpha=0 top=0 left=-320 ! mix. \
   filesrc location=./Cityscape1Min_720p_mp4.mp4 ! decodebin2 ! videorate ! video/x-raw-yuv, framerate=5/1, width=320, height=180 ! videobox border-alpha=0 top=-180 left=0 ! mix. \
   filesrc location=./Cityscape1Min_720p_mp4.mp4 ! decodebin2 ! videorate ! video/x-raw-yuv, framerate=5/1, width=320, height=180 ! videobox border-alpha=0 top=-180 left=-320 ! mix. \
   filesrc location=./Cityscape1Min_720p_mp4.mp4 ! decodebin2 ! videorate ! video/x-raw-yuv, framerate=5/1, width=640, height=360 ! mix.

I have tried the code and it works! BUT the cpu usage is 90%! It seems like the code not using vaapi / hw acceleration to play the videos. How to make it to play using mixvideodecoder?
