Now it is:

{
    "versions": {
        "program_version": {
            "version": "N-36604-g029c58b",
            "copyright": "Copyright (c) 2007-2012 the FFmpeg developers",
            "build_date": "Jan  8 2012",
            "build_time": "11:26:39",
            "compiler_type": "gcc",
            "compiler_version": "4.6.1",
            "configuration": ...
        },
        "library_versions": [
            {
                "name": "libavutil",
                "major": 51,
                "minor": 34,
                "micro": 100,
                "version": 3351140
            },
            {
                "name": "libavcodec",
                "major": 53,
                "minor": 54,
                "micro": 100,
                "version": 3487332
            },
            ...
        ]
    }
}           

JSON implementation is a little hacky since I had to fool the writer
to make it write a subsection, in compensation XML schema is pretty
compact and sweet:

<?xml version="1.0" encoding="UTF-8"?>
<ffprobe>
    <versions>
        <program_version version="N-36604-g029c58b" copyright="Copyright (c) 2007-2012 the FFmpeg developers" build_date="Jan  8 2012" build_time="11:26:39" compiler_type="gcc" compiler_version="4.6.1" configuration="..."/>
        <library_version name="libavutil" major="51" minor="34" micro="100" version="3351140"/>
        <library_version name="libavcodec" major="53" minor="54" micro="100" version="3487332"/>
        <library_version name="libavformat" major="53" minor="29" micro="100" version="3480932"/>
        <library_version name="libavdevice" major="53" minor="4" micro="100" version="3474532"/>
        <library_version name="libavfilter" major="2" minor="57" micro="101" version="145765"/>
        <library_version name="libswscale" major="2" minor="1" micro="100" version="131428"/>
        <library_version name="libswresample" major="0" minor="5" micro="100" version="1380"/>
        <library_version name="libpostproc" major="51" minor="2" micro="100" version="3342948"/>
    </versions>
</ffprobe>

Based on the previously posted JSON patches.
