Hello Irui,

Unfortunately, I can't reproduce your successful test with gstreamer: when
I try to encode a jpeg with videotestsrc input, I get a kernel panic.

To reproduce this behavior, please run the following:

gst-launch-1.0 videotestsrc ! v4l2jpegenc ! filesink location=hwenctest.jpg


Here's the panic log:
