所有设备的FFmpeg命令配置文件

I want to build online Audio/Video Converter with PHP.

I want to allow users to convert videos automatically without extra configuration like (Bit rate, codec, etc...) by just selecting device name [Ex: Samsung Galaxy S5].

So, I want pre configured file. That contains video configurations of all devices...

Please help me? About this. Open source project.

    FFmpeg can convert virtually between any video and audio formats.

    So assign "default" extension to every supported device and execute FFmpeg conversion with default values. Most of values are set by default, so all you need to do in CLI:

    ffmpeg -i InputFile.mov OutputFile.mpeg

    If need any additional parameters to specify, use documentation. Just keep in mind, that most of parameters position has different impact on output file (wasted around 6h looking for that "bug").
