Test method of double screen display based on SAIL-IMX6

Dual screens show the configuration of the same or different videos and related instructions

Home screen playback video instruction

Instruction 1:gst-launch-1.0 playbin uri= file:///IMG_6009.mp4

Instruction 2:gst-play-1.0

/ IMG_6009.mp4

The overlaysink plug-in is required to control video playback on different screens or on both screens at the same time (the system has been installed). The file for configuring overlaysink is / usr/share/imx_6q_display_config, and the configuration format is as follows:

[Display NAME] must be configured, referring to the display name

Device= must be configured to indicate device files, such as / dev/video17 or / dev/video18

Fmt= optional configuration, set display format, such as RGBP, RGB565, etc., default is RGBP

Width= optional configuration, set display resolution

Height= optional configuration, set display resolution

Alpha= optional configuration, set alpha (transparent) value, default 0

Color_key= optional configuration, color configuration, off by default

The specific configuration is as follows: (configure HDMI as the main screen and LCD as the secondary screen)

[master]

Device = / dev/video17

Fmt = RGBP

Alpha = 0

[slave]

Device = / dev/video18

Fmt = RGBP

Width = 800,

Height = 480

Depending on the above configuration, you can play different video instructions on different screens (HDMI+LCD) at the same time:

Gst-launch-1.0 playbinuri=file:/IMG_6008.mp4 playbinuri=file:/IMG_6009.mp4 video-sink= "overlaysink display-master=false display-slave=true"

To play the same video on different screens, you can run the following command:

Gst-launch-1.0 playbinuri=file:/IMG_6009.mp4 video-sink= "overlaysink display-master=truedisplay-slave=true"

Specify that the video is played on the secondary screen to run the following command:

Gst-launch-1.0 playbinuri=file:/IMG_6009.mp4 video-sink= "overlaysink display-master=falsedisplay-slave=true"

Play 4 videos on one screen with the following instructions:

Gst-launch-1.0 playbinuri=file:/IMG_6009.mp4 video-sink= "overlaysink overlay-width=240overlay-height=240" playbinuri=file:/ IMG6008.mp4 flags=0x41video-sink= "overlaysink overlay-left=240 overlay-width=240overlay-height=240" playbinuri=file:/ sample.mp4 flags=0x41video-sink= "overlaysink overlay-top=240 overlay-width=240overlay-height=240" playbinuri=file:/IMG_6009.mp4 flags=0x41video-sink= "overlaysink overlay-left=240 overlay-top=240 overlay-width=240overlay-height=240"
