Converting h264 to RGB on Jetson Nano

nick.j.meyer · November 19, 2023, 10:39pm

I’m attempting to convert an mp4 to RGB using GST. I get the following data when piping to the fake sink.

$ gst-launch-1.0 -v filesrc location=./test.mp4 ! decodebin ! fakesink silent=False

From this output, it seems I could add videoconvert ! video/x-raw,format=RGB and convert to RGB. However, I get the following error when doing so:

Any suggestions for getting this decoded to RGB?

Hi,
Please try the commands one by one:

$ gst-launch-1.0 filesrc location=test.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! fakesink

$ gst-launch-1.0 filesrc location=test.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nvvidconv ! video/x-raw, format=(string)RGBA ! fakesink

$ gst-launch-1.0 filesrc location=test.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nvvidconv ! video/x-raw, format=(string)RGBA ! videoconvert ! video/x-raw,format=RGB ! fakesink

Hello, Here is the output. I would expect to see some frame data from fakesink silent=False, but it doesn’t show much.

Also, the video is about 5 seconds long. It seems unexpected to see a very short execution time for the pipeline in the output below. How should I interpret that execution time?

Hi,
We are not sure how silent=False works. This would need other users to share experience.

There is no error in the prints and it looks like the frames are decoded. Please try the command and check whether RGB data is saved:

$ gst-launch-1.0 filesrc location=test.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nvvidconv ! “video/x-raw, format=(string)RGBA” ! videoconvert ! video/x-raw,format=RGB ! filesink location=dump.RGB

nick.j.meyer · December 12, 2023, 3:12pm

Looks like it works. Was able to see the data using appsink through python. Thanks for the help.
