1. 在waitFor()之前,利用单独两个线程,分别处理process的getInputStream()和getErrorSteam(),防止缓冲区被撑满,导致阻塞; 2. 记得释放文件流资源,以免导致“Too many open files”的错误; 代码如下: /** * 处理process输出流和错误流,防止进程阻塞 *在process.waitFor();前调用 * @param process */ private...

FFMpeg\Media\Audio can be transcoded too, ie: change codec, isolate audio or video. Frames can be extracted.TranscodingYou can transcode audios using the FFMpeg\Media\Audio:save method. You will pass a FFMpeg\Format\FormatInterface for that....
FFmpeg libav has lots of bindings for many languages like python, go and even if your language doesn't have it, you can still support it through the ffi (here's an example with Lua).We'll start with a quick lesson about what is video, audio, codec and container and then we'll go...
