Max resolution omxh264enc is 4096x4096 on Tegra Tk1?


I want to encode 6000x3000 frames via HW NVIDIA encoder( now it is gst omxh264enc ). But it crops video to 4096x3000. It is possible to HW encode more than 4096?

Best regards, Viktor.

Hi vsw,

4096x4096 on Tegra Tk1?
No, our encoder supports resolutions upto 4K, you will need to do frame scaling by nvvidconv to downscale the frame size.

But it crops video to 4096x3000.
What’s your gstreamer pipeline for this use case?


Thank you Kayccc,

Here is my working pipline str for parse:
“appsrc name=source ! video/x-raw, format=UYVY, width=4096, height=2048, framerate=5/1 !”
//“videotestsrc num-buffers=100 ! video/x-raw, format=UYVY, width=4096, height=2048, framerate=14/1 !”
“nvvidconv ! video/x-raw(memory:NVMM) !”
“omxh264enc ! video/x-h264, stream-format=byte-stream !”
“h264parse ! mpegtsmux !”
“filesink location=/home/ubuntu/test.ts”;

Yes i resize input frame via nppiresize now.

Following this question and based on the latest gstreamer guide (Release 27.1) I want to understnad the maximal frame resolution and the frame rate supported by the latest gstreamer version - Is it 4208 X 3120 (in CSI mode)?
if positive what is the supported output frame rate?

Hi amirfr,

The Release 27.1 is for TX2 only, are you asking this issue for TX2?


First thanks for your response.
Since I suspect my question was not clear and sharp enough, I will try to sharpen it now.
Our setup is Jetson TX1 (over Auvidea J120 IMU board). We also use the H.264 encoder.
The question is what is the maximal video resolution and frame rate that can be achieved for this setup.
From your answer (and to my surprise) it seems that using Release 27.1 for our setup is not adequate. If this is correct which version should we use (e.g., the most updated one)?
Furthermore, to our understanding TX1 using omxh264enc can do 4096x4096 frame in 1 fps rate. However we tried this and it failed.
I will be glad to get your clarifications on this topic
Thanks a lot

R24.2.1 is the most recent TX1 L4T release.

Hi amirfr,
