Question

So I want to compile FFMpeg C libraries (as static) not in its full default glory but for my purposes only – so that it would contain:

• 2 codec formats MP3 and FLV1 (H.263)
• 2 file (container) formats MP3 and FLV

Of course I only want to limit only range of formats and codecs. Not functions of FFmpeg.

How to do such thing?

What is my main point:

To have such ffmpeg build that when I call function like

multiplexer::multiplexer(std::string container)
{
        av_register_all();

        this->format_context = avformat_alloc_context();
        if (this->format_context == NULL)
        {
                std::cout << "Multiplexer: format context is empty." << std::endl;
                throw internal_exception();
        }

        this->format_context->oformat = av_guess_format(container.c_str(), NULL, NULL);
        if (this->format_context->oformat == NULL)
        {
                std::cout << "Multiplexer: invalid container format (" << container << ")." << std::endl;
                throw internal_exception();
        }
}

I would be limited to FLV only

The configure script has a list of options. Run ./configure --help to see them. I’m not sure how options stack, but you could try --disable-everything followed by --enable-demuxer=flv etc.
