"This update for ffmpeg to version 3.3 fixes several issues.

These security issues were fixed :

  - CVE-2016-10190: Heap-based buffer overflow in
    libavformat/http.c in FFmpeg allowed remote web servers
    to execute arbitrary code via a negative chunk size in
    an HTTP response (boo#1022920)

  - CVE-2016-10191: Heap-based buffer overflow in
    libavformat/rtmppkt.c in FFmpeg allowed remote attackers
    to execute arbitrary code by leveraging failure to check
    for RTMP packet size mismatches (boo#1022921)

  - CVE-2016-10192: Heap-based buffer overflow in ffserver.c
    in FFmpeg allowed remote attackers to execute arbitrary
    code by leveraging failure to check chunk size
    (boo#1022922)

  - CVE-2017-7859: FFmpeg had an out-of-bounds write caused
    by a heap-based buffer overflow related to the
    ff_h264_slice_context_init function in
    libavcodec/h264dec.c (bsc#1034183).

  - CVE-2017-7862: FFmpeg had an out-of-bounds write caused
    by a heap-based buffer overflow related to the
    decode_frame function in libavcodec/pictordec.c
    (bsc#1034181).

  - CVE-2017-7863: FFmpeg had an out-of-bounds write caused
    by a heap-based buffer overflow related to the
    decode_frame_common function in libavcodec/pngdec.c
    (boo#1034179)

  - CVE-2017-7865: FFmpeg had an out-of-bounds write caused
    by a heap-based buffer overflow related to the
    ipvideo_decode_block_opcode_0xA function in
    libavcodec/interplayvideo.c and the
    avcodec_align_dimensions2 function in libavcodec/utils.c
    (boo#1034177)

  - CVE-2017-7866: FFmpeg had an out-of-bounds write caused
    by a stack-based buffer overflow related to the
    decode_zbuf function in libavcodec/pngdec.c
    (boo#1034176)

These non-security issues were fixed :

  - Enable ac3 

  - Enable mp3 decoding

  - EBU R128 implementation now within ffmpeg, not relying
    on external library anymore

  - New video filters 'premultiply', 'readeia608',
    'threshold', 'midequalizer'

  - Support for spherical videos

  - New decoders: 16.8 and 24.0 floating point PCM, XPM

  - New demuxers: MIDI Sample Dump Standard, Sample Dump
    eXchange demuxer

  - MJPEG encoding uses Optimal Huffman tables now

  - Native Opus encoder

  - Support .mov with multiple sample description tables

  - Removed the legacy X11 screen grabber, use XCB instead

  - Removed asyncts filter (use af_aresample instead)"
