My bsp is yocto1.7 and board is VAB820(base on imx6q).
As part 3.4.1 of the document "i.mx_6_Series_Yocto_Project_Multimedia_User's_Guide.pdf" , I try to playback the two different videos to HDMI and LVDS separately with imx_v4l2sink.
gst-launch playbin2 uri=file:///$file1 video-sink="imx_v4l2sink device=/dev/video17" &
gst-launch playbin2 uri=file:///$file2 video-sink="imx_v4l2sink device=/dev/video19"
But the HDMI is product black screen , and product some warning info like "imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000 " in serials.
At mean time in HDMI the video will be transparent to desktop.
When I use mfw_isink to check the function:
export VSALPHA=1
gst-launch playbin2 uri=file:///$file1 video-sink="mfw_isink display=LVDS" playbin2 uri=file:///$file2 video-sink="mfw_isink display=HDMI"
Use vssconfig.dual.lvds_hdmi as the vssconfig file.
But only the video can playback on LVDS , in HDMI showed blurred screen. And the performance is very low.
For above issues , please give me some advice . Thanks!!!
