Gstreamer pipeline for .264 file

Autonomous Machines Jetson & Embedded Systems Jetson Nano

Tried a few pipelines to play this file. Plays ok with “ffplay -flags2 showall” Any help using the HW decoding would be great, Can’t seem to get the pipe to play.

Hi,
You may try jetsom_multimedia_api decoding sample:

nvidia@nvidia-desktop:/usr/src/jetson_multimedia_api/samples/00_video_decode$ ./video_decode H264 /home/nvidia/test.264

No luck. This works but I was wanting it on the GPU process.
gst-launch-1.0 filesrc location=main.h264 ! h264parse ! avdec_h264 ! xvimagesink

Hi,
Would like to clarify that there is individual hardware decoder on Jetson platforms, so hardware decoding is not done on GPU.

Yes, Using a Jetson Nano. But haven’t had luck with it. Will PM you a link to the file if you want to try it or possibly troubleshoot it.

Hi,
Please try

$ gst-launch-1.0 filesrc location= MainCam_2020-8-17_19-20-1.h264 ! h264parse ! nvv4l2decoder enable-frame-type-reporting=1 ! nvoverlaysink

This is same as

Hi,
You should see video playback. No?

10

Negative

Hi,
We can see video playback in running the gstreamer pipeline. A bit strange you cannot see it. The log looks OK. Maybe you can do clean re-flash and try again.

Will try, Thanks for the help.

I have similar issue.
I’d like to use the gstreamer.
My file can be played, but it’s a little laggy.
My pipeline is as follows.

gst-launch-1.0 filesrc location=/home/nvidia/test264.h264 ! h264parse ! nvv4l2decoder enable-frame-type-reporting=1 ! nvvidconv output-buffers=20 ! ‘vid
eo/x-raw(memory:NVMM), format=RGBA, width=1920, height=1080, framerate=30/1’ ! queue ! nvoverlaysink

The log at that time is as follows.
What should I do ?
