Hi,

I am looking for an example which uses samsung jpeg v4l2 mem2mem driver.
For example the 'Exynos4 JPEG codec v4l2 driver' described here
http://lwn.net/Articles/468547


I am new to linux v4l2 driver. I am looking for example to pass an
input image to hardware accelerated encoder/decoder.

Thank you.

I have pushed some test application to a git repository at [1]. It can be
used for JPEG files encoding/decoding with the mainline s5p-jpeg driver.
A v4l2-jpeg-codec-test directory should appear there within few hours.

Thanks for the test application.

But I don' see the test directory in the repository mention here:
http://git.infradead.org/users/kmpark/public-apps/tree/refs/heads/master

Thank you again.
