mxc_vpu_test.out播放视频

[1182614726]

大家好，

            使用./mxc_vpu_test.out -D "-i akiyo.mp4 -f 0"播放unit_tests目录下的akiyo.mp4视频，报“unable to open /dev/video17”,请问这是怎么回事呢？

[joanxie]

what board do you use? imx6S?

pls try to use the command as below, tell me what you get

cat /sys/class/graphics/fb0/mode? when the board boot up, dose anything show on the display?

[1182614726]

you are right, the chip I use is imx6solo. the output of the command is "U:1920x1080p-60", now the display I use is HDMI

[joanxie]

how about when you use "gplay-1.0 akiyo.mp4" ? pls check the log file if the board detect the hdmi or not, or check if your uboot set the correct hdmi output

[1182614726]

my hdmi output is normal, it can display picture from uboot to kernel, until the QT to run.

when i use gplay-1.0 akiyo.mp4, it output the wrong message like below:

do you mind telling me what bsp version you use? do you use demo image or image you built? let me reproduce this on my imx6S board. and pls send the log file to me. let me double check it

[1182614726]

Hi Joan,

            Thank you very much. now the bsp i use is L4.1.15-2.1.0，I download my yocto bsp from imx-4.1-krogoth, the kernel built version is L4.1.15, uboot version is 2016.03.

[joanxie]

 I tested this bsp with demo image successfully last year, do you use the image you build by yourself? could you share the log file when the board boot up? let me double check it,

I don't find kernel command from your log file, I'm not sure if you set output to different frame buffer, if you use HDMI as primary output, try to add "video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24" in the uboot, or use ./mxc_vpu_test.out -D "-i akiyo.mp4 -f 0 -x16" , x16 means video16, you can try to use x16 or x18, to check the output device status, you also can use the command “cat /sys/class/video4linux/video17/name”,

[1182614726]

你好，非常抱歉，之前做系统优化，把串口驱动初始化之前的log全部去掉了。

1.我目前使用的是HDMI作为输出，在命令行中的参数为：

video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off hdmi_audio_clk=148500000

2.在/sys/class/video4linux下没有任何设备节点

3.执行./mxc_vpu_test.out -D "-i akiyo.mp4 -f 0 -x16“命令报如下错误：

since you use mxcfb1, pls try to use the command "./mxc_vpu_test.out -D "-i akiyo.mp4 -f 0 -x18“
