  • FFmpeg 2.1 试用(新版支持HEVC,VP9)

    前两天帮一位老师转码图像的时候,无意间发现新版FFmpeg竟然支持了下一代编码标准HEVC,以及Google提出的下一代编码标准VP9。真心没想到FFmpeg对下一代的编码标准支持的是如此之快。我还以为这两种编码标准还要在实验室呆上1年呢。看来这两种编码标准离大规模应用已经不远了。


    下面是其更新列表,红色部分为其新增加的HEVC和VP9的支持:

     - aecho filter
    - perspective filter ported from libmpcodecs
    - ffprobe -show_programs option
    - compand filter
    - RTMP seek support
    - when transcoding with ffmpeg (i.e. not streamcopying), -ss is now accurate
      even when used as an input option. Previous behavior can be restored with
      the -noaccurate_seek option.
    - ffmpeg -t option can now be used for inputs, to limit the duration of
      data read from an input file
    - incomplete Voxware MetaSound decoder
    - read EXIF metadata from JPEG
    - DVB teletext decoder
    - phase filter ported from libmpcodecs
    - w3fdif filter
    - Opus support in Matroska
    - FFV1 version 1.3 is stable and no longer experimental
    - FFV1: YUVA(444,422,420) 9, 10 and 16 bit support
    - changed DTS stream id in lavf mpeg ps muxer from 0x8a to 0x88, to be
      more consistent with other muxers.
    - adelay filter
    - pullup filter ported from libmpcodecs
    - ffprobe -read_intervals option
    - Lossless and alpha support for WebP decoder
    - Error Resilient AAC syntax (ER AAC LC) decoding
    - Low Delay AAC (ER AAC LD) decoding
    - mux chapters in ASF files
    - SFTP protocol (via libssh)
    - libx264: add ability to encode in YUVJ422P and YUVJ444P
    - Fraps: use BT.709 colorspace by default for yuv, as reference fraps decoder does
    - make decoding alpha optional for prores, ffv1 and vp6 by setting
      the skip_alpha flag.
    - ladspa wrapper filter
    - native VP9 decoder
    - dpx parser
    - max_error_rate parameter in ffmpeg
    - PulseAudio output device
    - ReplayGain scanner
    - Enhanced Low Delay AAC (ER AAC ELD) decoding (no LD SBR support)
    - Linux framebuffer output device
    - HEVC decoder, raw HEVC demuxer, HEVC demuxing in TS, Matroska and MP4
    - mergeplanes filter

    于是果断试了一下,用ffplay播放了一下实验室里的HEVC序列以及VP9序列,发现播放高清序列很流畅,不卡。
