Test the encoding effect of h265 and H264

Os:centos6.4-64bit

--------compiling FFMPEG with h265--------

1. Installing HG Tool

#yum Install HG

2. Download x265 source code and make

#hg Clone https://bitbucket.org/multicoreware/x265

#cd X265/build/linux

#make

#make Install

3. Download x264 and FFmpeg source and make

Please refer to one of my previous blog posts:

Use Nginx+ffmpeg to build HLS live Transcoding server (http://blog.csdn.net/wutong_login/article/details/42292787)

4. Compile support for h265 FFMPEG

#PKG_CONFIG_PATH =/usr/local/lib/pkgconfig./configure--prefix=/opt/ffmpeg/--enable-version3--ENABLE-LIBVPX-- ENABLE-LIBFAAC--enable-libmp3lame--enable-libvorbis--enable-libx264--enable-libxvid--enable-shared--ENABLE-GPL --enable-postproc--enable-nonfree--enable-avfilter--enable-pthreads--enable-libx265

#make

#make Install

#ldd/opt/ffmpeg/bin/ffmpeg

Note:if libx265.so.40 isn't found please cp it from/usr/local/lib to/usr/lib64

--------Compare h265 and H264--------

1. Encode 264 and 265

Find a YUV file from the Internet, or use ffmpeg decoding one can also, I use 720P, respectively encoded 500Kbps.

/opt/ffmpeg/bin/ffmpeg-s 1280*720-i/home/edward/media/720-new.yuv-vcodec libx264-b:v 2000k/home/edward/media/720- New-264.ts

/opt/ffmpeg/bin/ffmpeg-s 1280*720-i/home/edward/media/720-new.yuv-vcodec libx265-b:v 2000k/home/edward/media/720- New-265.ts

Then decode to YUV data:

/opt/ffmpeg/bin/ffmpeg-i/HOME/EDWARD/MEDIA/720-NEW-264.TS/HOME/EDWARD/MEDIA/720-NEW-264.YUV

/opt/ffmpeg/bin/ffmpeg-i/HOME/EDWARD/MEDIA/720-NEW-265.TS/HOME/EDWARD/MEDIA/720-NEW-265.YUV

Find a frame to compare:

265:

264:

As we can see, 264 code 500k, the figure in the red box of several numbers, the basic has not been clearly seen.
