Hi,
We are using a TX2 to record 6 Camera modules simultaneously at 1080p@60fps and we have set the encoding to H.265 at 16 Mbps (also tried with 10Mbps) for each video pipeline. We have noticed, after breaking down the video frame by frame with ffmpeg, there were a lot of duplicate frames.
Can someone advise please? Can the TX2 not encode 6 x 1080p at 60fps?
Kind Regards,
Hi Devashish,
We have veirifed 6 1080p60 on TX2. Please refer to

Hi DaneLLL,
The video that you are encoding are already saved videos. We are encoding while recording, I think this is what’s causing the drop in frames.
Could that be an issue?
Hi DaneLLL,
Have you had a chance to investigate on the matter?
Hi, what is your camera source? Since encoder can achieve 6 1080p60. The issue looks like the camera source cannot keep 6 1080p60
Hi DaneLLL,
I am not sure what you mean by camera source but we have custom made IMX290 modules which drivers’ was written by Leopard Imaging and they say that all is working fine on their side and I should check with NVIDIA why that issue is occurring. That’s why am here.
Hi,
Below is listed in document:

The spec is 4kp30. The above case is pure encoding test and may not be achieved in real camera case. It depends on implementation.
Do you implement in gstreamer or MMAPI? Which CSI ports of TX2 are connected? Does it use TX2 ISP engine?
Hi,
We specifically ask for real case encoding before we went with the Jetson TX2 for this project. Now this is very problematic, isn’t it?!
Which implementation are you referring to, where it will be suitable for the 6 x 1080p60fps real case encoding?
We are using gstreamer. All of the CSI ports are connected to the camera modules, 2 lanes each module x 6 modules. Yes it uses the TX2 ISP engine.
Hi Devashish,
How many 1080p60 can you achieve with imx290?
Hi DaneLLL,
Am not sure I understood your question.
We have 6 IMX290 connected to the Jetson TX2 and each IMX290 goes through MIPI CSI 2 lanes
Hi Devashish,
If you run one imx290 with encoding, can it achieve 1080p60 without dropping frames?
If you run two imx290 with encoding, can it achieve two 1080p60 without dropping frames?
How many can you run without dropping frames? Do you run gstreamer or MMAPI?
Hi DaneLLL,
Sorry for such late reply.
The encoding is good up to 3 x 1080p60. After that it starts dropping frames.
Best,
Hi Devashish,
If you run 4 imx290, can you see them all in 1080p60 with fpsdisplaysink?
Here is a example:

Also do you have configure any encoder property of omxh265enc?

This is the result of the fpsdisplaysink.
We set the bitrate to a specific value and set the control rate to fixed but it still varies. Other than that we did not change other properties
Hi Devashish,
The issue is in the camera sources which cannot achieve 1080p60.
Hi DaneLLL,
Does this mean that the driver is wrong?
Hi Devashish,
We have discussion with Leopard and confirms six 1080p60 camra inputs are not guaranteed. The BSP release does not support this usecase.
