[FFmpeg-devel] [PATCHv6 1/4] Move lavd/v4l2-common.* to lavc
Jorge Ramirez-Ortiz

Fri Aug 25 14:22:45 EEST 2017
From: Alexis Ballier <aballier at gentoo.org>
In preparation to support the integation of the V4L2 API for encoding
and decoding, move v4l2 related files to libavcodec.
v4l2-common was renamed to v4l2_fmt for clarity (v4l2-common.h belongs
to the V4L2 API)
