- drop patch merged upstream:
  * 0001-avformat-img2dec-fix-infinite-loop.patch

- Fix typo in swresample name

- Conditionalize vidstab so it gets working on Leap
- full_build only on Leap 42 and 15, not on TW

- Add macros to allow conflicting with all other devel projects
  to ensure we always install only one specific ffmpeg

- Enable vidstab on tumbleweed

- Conditionalize pkgconfig(libopenjpeg) and pkgconfig(sdl2)
  BuildRequires: Fix build for SLE 12 SP3.
- Enable pkgconfig(vidstab) BuildRequires unconditionally, now
  available in openSUSE.

- Conditionalize zimg for Leap 42.3

- Split out the develpkgs again
- Use %autopatch

- Sync with ffmpeg-4

- Add 0001-avformat-img2dec-fix-infinite-loop.patch [boo#1090826]

- Enable build against libzimg.

- Add 0001-opusenc-psy-disable-stereo-searches.patch
  to fix a crash in the Opus encoder when outputting mono.
- Enable FFmpeg Opus encoder as a selectable runtime alternative
  to Xiph libopus.

- Create a new package ffmpeg-private-devel which contains some
  headers under /usr/include/ffmpeg/private that were not installed
  by upstream. Those headers are needed by the libav package in order
  to build avconv and other tools using the libav* libraries generated
  by ffmpeg instead of its own. No other package should require
  ffmpeg-private-devel.

- Build and install also the sidxindex tool

- Enable mpeg1video and mpeg2video in enable_decoders, and remove
  it from disable-decoders call given to configure, mpeg2 now
  available in openSUSE.

- enable video stabilization/deshaking via libvidstab (optional)

- Update to new bugfix release 3.4.2
  * Fix integer overflows, multiplication overflows, undefined
    shifts, and verify buffer lengths.

    [boo#1079368, CVE-2018-6621]
- Enable use of libzvbi for displaying teletext subtitles.
- Fixed a DoS in swri_audio_convert(), added cve-2017-17555.diff
  [boo#1072366, CVE-2017-17555].

- Update to new bugfix release 3.4.1
  * Fixed integer overflows, division by zero, illegal bit shifts
  * Fixed the gmc_mmx function which failed to validate width
    and height [boo#1070762, CVE-2017-17081]
  * Fixed out-of-bounds in VC-2 encoder [boo#1069407, CVE-2017-16840]
  * ffplay: use SDL2 audio API

  (upstreamed).

- Add 0001-avcodec-x86-mpegvideodsp-Fix-signedness-bug-in-need_.patch
  [boo#1070762]
