JPEG encode with Gstreamer in memory

asked 2019-01-25 01:57:13 -0600

Hi. I want to encode\decode jpeg in memory using one of the gstreamer plugins, i.e. use smth like "appsrc ! jpegenc ! appsink" configuration. Is it possible with VideoCapture, VideoWriter? Thanks.

Why not use imencode? VideoCapture and VideoWriter do not support this configuration, you should use GStreamer directly.

I don't use imencode bcz I want to use NVIDIA Tegra hardware-accelerated JPEG encoding module nvjpegenc.

This works like a charm:

"appsrc name=appsrc blocksize=921600 ! video/x-raw,format=RGB,width=640,height=480,framerate=1/1 ! jpegenc ! appsink name=appsink"

When changing jpegenc to nvjpegenc (Jetson AGX Xavier), there's something wrong with the buffering.
