Problems encountered in compiling FFMPEG in Windows

Only ffprobe.exe, ffmpeg.exe, and ffplay.exe are compiled on the first line. This may be because SDL is not installed yet. Check whether SDL is installed. In the case of configurecompiled by ffmpeg, if there is no sdlin the response, ffplay.exe will not be generated if there is no sdlin.

2nd release when the problem does not compile ffplay.exe, test, found that can not play, prompt "No avcodec-54.dll found ". Let me reinstall it, maybe it can solve this problem. Then I will try again. --- I re-compiled it, modified some parameters, and forgot how to solve it .. There are other problems later.

3. After make install of FFMPEG, the system prompts that avdevice. Lib cannot be found.

4. In configure, "GCC is unable to create an executable file" appears. I can change the configure parameter.

I deleted the last parameter. I don't know if it will affect the subsequent compilation.
