hi all,

I am planning to get imx6 quad or dual, for an dual or three camera interface, is it possible to make a dual camera in these boards

Thanks,

On the Linux BSP (LTIB 3.0.35_4.0.1) , there is currently an issue with two cameras capturing and data being display concurrently. If you are not displaying both (just capturing + encoding, for example) with current BSP you can use MIPI and Parallel at the same time. As I said, my comment is meant for Linux.

hi leo,

Is possible to operate both the cameras simultaneously, i want both the cameras to capture the jpeg images at a time, is this possible with one vpu to compress both the camera images at a time

Thanks,

Hi,

Usually, some cameras output its data already compressed (MJPEG), so there is no need to compress it. Or you mean decompress? In case the camera outputs in raw format, you can use the vpuenc gstreamer element to encode it. Just make sure you select the correct codec value.

hi leo,

Thanks for your reply,

My requirement is Dual Camera connected with MIPI and Parallel interface; I need to stream both cameras simultaneously in H264 format.

As per my understanding, IMX-D has 2xIPC and 1 xVPU

The Application creates multiple instance of VPU and encodes video into H264(1080P). Two cameras should be compressed simultaneously by the VPU core. can you plz conform it

Thanks,

That is a viable scenario, but the fps must be at most 24 and the VPU must run @ 352MHz. Also, H264 encoding just support BP profile.

hi leo,

Thanks for your support, we are working on this

One more suggestion i need, now we are using imx535 with a camera interface for live streaming and recording purpose in which we are using the RTP and RTSP protocol for live streaming, i want to know which protocol is best for live streaming videos, such as http, rtp, rtsp etc., can you suggest which protocol is best for live streaming and recording videos

Note:

And if i want to stream and record the videos of dual camera simultaneously, is there any gst-launch command document for this

Thanks

shan
