Evaluation Crowns FFmpeg the King of the H.264编码器
Want to know what to encode with for great H.264个文件? 罗伯特•莱因哈特, founder of VideoRx.com，很高兴告诉你. One minute into his recent 流媒体 West presentation on how to evaluate H.264 encoders he gave the big reveal: FFmpeg is the best choice around.
"I'll give you the conclusion, which is you can pretty much accomplish the best encoding with FFmpeg and x264, 正确的? There is no way to get around the fact that Sorenson and Telestream and Harmonic or whoever decides to license x264, 好吧, we all have access to those same parameters in FFmpeg. It's the same exact codec,莱因哈特说.
FFmpeg is a great choice for the budget-conscious because it's a free download. But, Reinhardt cautions, that doesn't mean there's no cost.
"The adage 'You get what you pay for' doesn't even really apply anymore given that something like FFmpeg as a tool doesn't cost you anything,莱因哈特说. "Now, we all know, I hope, the difference between price versus cost, 正确的? The price tag of FFmpeg is zero, but what is the cost of using FFmpeg? You need someone who knows how to use a command line utility, knows how to integrate it with your workflow, and is comfortable with that. I'm a geek; I have no problem setting up scripts that are going to automate FFmpeg to fit into a workflow just like a commercial product."

Not all video encoders are created equal.
