Hi
I test test tw9992 video decoder by mx8_v4l2_cap_drm in below case
./mx8_v4l2_cap_drm -cam 1 -d "/dev/video1" -fmt YUYV -of
It create a YUYV raw data, I check it by vooya tool in ubuntu environment
There are two field on the screen
I take this for reference, then try to set deinterlace_mode in dts
ISL79987 and adv7180 de-interlace driver for iMX8QXP boards
&isi_4 {
+ deinterlace_mode = <2>; /* 0 ~ 1: No de-interlacing,
+ 2: Odd even weave, 3: Even odd weave
+ 4: Odd even blending, 5: Even odd blending
+ 6 ~ 7: Line doubling */
+ status = "okay";
};
Finally, I found it stuck in this case
ret = ioctl(fd, VIDIOC_DQBUF, &buf);
I dump MIPI CSI register as below, you can also check it in log file as attachment
Can you provide some suggestions?
