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。 播放序列截图 1920x1080逐行扫描 ffplay播放VP9时候控制台输出 ffplay播放hevc时候控制台输出 上传了一份FFmpeg 2.1http://download.csdn.net/detail/leixiaohua1020/6486599 补充 HEVC测试序列合集http://download.csdn.net/detail/leixiaohua1020/6843803 VP9测试序列合集http://download.csdn.net/detail/leixiaohua1020/6843921 转载于:https://my.oschina.net/leixiaohua1020/blog/302172
