I have installed R28.2 on my TX2 board. The version of Gstreamer is 1.8.3. Using the document ‘Jesson_TX1_and_TX2_Accelerated_Gstreamer_User_Guide.pdf’, I want to sent the profile of omxh265enc, but it shows that the no “profile” in omxh265enc. What is the problem? Thank you very much.

Please try

gst-launch-1.0 videotestsrc num-buffers=200 ! \
'video/x-raw, width=(int)1280, height=(int)720, \
format=(string)I420' ! omxh265enc ! 'video/x-h265,profile=main' ! matroskamux ! \
filesink location=test.mkv -e

We only support main profile for h265, so it does not matter if you set it or not.

Thank you. If I want to sent the level or insert-sps-pps of omxh265enc, it still shows that the no “profile” (no insert-sps-pps) in omxh265enc. What is the problem? The version of libgstomx.so is 1.0.0.1.

You can enable insert-sps-pps by configuring stream-format=byte-stream

gst-launch-1.0 videotestsrc num-buffers=200 ! \
'video/x-raw, width=(int)1280, height=(int)720, \
format=(string)I420' ! omxh265enc ! 'video/x-h265,profile=main,stream-format=byte-stream' ! \
h265parse ! matroskamux ! filesink location=test.mkv -e

Hi DaneLLL,
How about level and tier of H.265 encoder?
I use following command

gst-launch-1.0 videotestsrc num-buffers=180 ! 'video/x-raw, width=(int)3840, height=(int)2160, format=(string)I420' ! omxh265enc ! 'video/x-h265,profile=main,level=main5,stream-format=hvc1' ! h265parse ! mp4mux ! filesink location=test.mp4 -e

And use ffprobe to check profile and level

ffprobe test.mp4 -show_entries stream=profile,level

The result is

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mp4':

It show that, level is 20, what is this mean?
Thank

Hi,
I cannot launch your pipeline on r28.2.1 unless I replace mp4mux with matroskamux.

And ffprobe shows:

[STREAM]
profile=Main
level=150
[/STREAM]

Please check [ITU-T H.265(ISO/IEC 23008-2), A.4 Tiers and levels] at
https://gist.github.com/yohhoy/2abc28b611797e7b407ae98faa7430e7

Hi DaneLLL,
I also change mp4mux with matroskamux but the same result happen

[STREAM]
profile=Main
level=20
[/STREAM]

I attached file that was generated by gstreamer.
P.S. I compile libgstomx from source
Thank

Hi,
Could you check if you are on r28.2.1?

head -1 /etc/nv_tegra_release

Hi DaneLLL,
I am using Jetpack 3.1, r28.1

# R28 (release), REVISION: 1.0, GCID: 9379712, BOARD: t186ref, EABI: aarch64, DATE: Thu Jul 20 07:59:31 UTC 2017

What should I do next?
Thank

Dear DaneLLL,
Could you attached your “libgstomx.so”, I want to check encoder work well or not.
Thank.
