i.MX6 gstreamer dual record fail

[m_c]

1) We use Use L3.0.35_4.1.0_130816_images_MX6.tar.gz on i.MX6Q-SDP with below commands to do dual record but fail.

2) Have to submit SR, but he suggest post here.

3) Also try the apply unoffical patch from <OV5640 and OV5642 cameras on iMX6 | Freescale Community>, and it can do dual record. But will encounter performance issue while playing movie.

The latest mxc V4L2 capture driver supports 2 cameras simultaneously.

The below v4l2 capture unit test command lines may verify this feature on MX6 SabreSD platform:

root@freescale /unit_tests$ ./mxc_v4l2_capture.out -iw 1024 -ih 768  -ow 1024 -oh 768  -m 8 -fr 15 -d /dev/video0 -i 1 -c 100 /test1.yuv & root@freescale /unit_tests$ ./mxc_v4l2_capture.out -iw 1024 -ih 768  -ow 1024 -oh 768  -m 8 -fr 15 -d /dev/video1 -i 0 -c 100 /test2.yuv in_width = 1024, in_height = 768 out_width = 1024, out_height = 768 top = 0, left = 0 in_width = 1024, in_height = 768 out_width = 1024, out_height = 768 top = 0, left = 0

Hi m.c,

Rogerio and Daiane have replied to you in Re: i.MX6 gstreamer dual record fail

Could you please try the latest kernel from git repository?
