I see you figured that out. But let me repeat: the smallest executable set (.dlls + .exe) is to use static linking - configure --enable-static --disable-shared to make sure that you don't link in any shared library by mistake. If you do that, everything you need will be inside your .exe and you will not need any of the ffmpeg av*.dll files. When I select just the parts I need (encoders, decoders, parser, etc), I can get down to 4MB static executable (that does not need any .dll and includes my own code as well as everything from ffmpeg that I need), and upx actually cuts that down to ~1MB. However, the license (LGPL) requires that you let user upgrade the library without your help. That is usually easy to achieve when you ship .dlls, but not as easy when you do static linking. If you use a GPL component (e.g. the x264 encoder), you will need to make your project GPL as well, which means releasing complete buildable sources of every executable you deliver, or at the very least making an offer to provide those. (Thanks to Carl Eugen Hoyos for correcting my earlier wrong statement about the LGPL - I had the GPL and LGPL confused). |
