From 487381abe368a430cdfb226cf69f6ba6e2481eff Mon Sep 17 00:00:00 2001 From: Jacek Anaszewski Date: Wed, 8 Jan 2014 16:35:36 +0100 Subject: v4l2-jpeg-codec-test: version 0.1 The run_fmt_test.sh script currently uses a hack to retrieve the JPEG codec video node names. Normally those names should be retrieved from sysfs or using libudev.
