Screen flickering when playing multiple videos with rkximagesink
#1
Hello,

I am running gstreamer-rockchip-extra on Rock64 SBC (RK3328) with the following software.
  • Linux kernel 4.4.120-rockchip-ayufan-209
  • gstreamer-rockchip-extra 1.10
  • gstreamer-rockchip 1.10-5ayufan12
  • librockchip-mpp1 1.4.0-1ayufan3-2
I try to run two H264 video simultaneously as the following:
Code:
gst-launch-1.0 uridecodebin uri=file:///home/rock64/big_buck_bunny_480p_h264.mov ! rkximagesink

I see constant flickering in both windows. It seems that every other frame is replaced by black rectangle.
Short video explaining what I see is available at https://transfer.sh/j1PII/gst-rockchip.mp4

Here is initial github issue:

https://github.com/rockchip-linux/gstrea...a/issues/2

But people at #rockchip-linux IRC channel said that they do not reply at github and I have to report it here.

This is why I am writing it here. RockChip closes every issue without reply:
