一、需要的环境： ①MinGW ②yasm.exe ③pexports.exe ④x264源码文件 二、搭建环境 ①安装MinGW 下载地址： https://sourceforge.net/projects/mingw/，下载完成后安装完成进入界面，如下图 选"Basic Setup"，将右侧的选项全部选中，点击菜单上的“Installation”下的“Apply Changes”开始安装。等待安装完成，这个过程需要的时间比较长，如果有个别未来安装成功，重试几次就好了。 ②下载yasm.exe 下载地址： http://yasm.tortall.net/Download.html，下载对应的版本即可。 下载后将文件名称改成yasm.exe，放在MinGW\bin下。根据MinGW的安装位置确定。 ③下载pexports.exe 下载地址： https://sourceforge.net/projects/mingw/files/MinGW/Extension/pexports/ ,下载完成后将pexports.exe放在VisualStudio的安装目录的\VC\bin下，打开vs的命令行工具，输入pexports，出现下面的提示表示配置完成。 ④下载x264源码和编译 下载地址： http://download.videolan.org/pub/videolan/x264

How does one encode a series of images into H264 using the x264 C API?

How does one use the x264 C API to encode RBG images into H264 frames? I already created a sequence of RBG images, how can I now transform that sequence into a sequence of H264 frames? In particular, how do I encode this sequence of RGB images into a sequence of H264 frame consisting of a single initial H264 keyframe followed by dependent H264 frames? KillianDS First of all: check the x264.h file, it contains more or less the reference for each function and structure. The x264.c file you can find in the download contains a sample implementation. Most people say to base yourself on that one,

Generating movie from python without saving individual frames to files

由 ﹥＞﹥吖頭↗ 提交于 2019-11-26 10:08:31
问题 I would like to create an h264 or divx movie from frames that I generate in a python script in matplotlib. There are about 100k frames in this movie. In examples on the web [eg. 1], I have only seen the method of saving each frame as a png and then running mencoder or ffmpeg on these files. In my case, saving each frame is impractical. Is there a way to take a plot generated from matplotlib and pipe it directly to ffmpeg, generating no intermediate files? Programming with ffmpeg\'s C-api is
