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。
