   9 This reverts commit b344c71f3e03f912d8b6ee7d96cdd67b31cdf8cc.
  10
  11 avcodec_encode_video2() has been introduced in lavc 54.01.0 but Debian Wheezy
  12 ships with lavc 53, so for now we should revert this change for the Debian
  13 packages.
  14
  15 When this patch will be dropped maybe the package should depend on
  16 libavcodec54 as the old API may be disabled in the Debian packages.
