Subject: ffmpeg: define fallback macro AV_VERSION_INT()

For ffmpeg < 0.5.  Copied from libavutil 0.5.

ffmpeg: don't use deprecated CODEC_TYPE_AUDIO with new lavc

fixes build with lavc 53.

ffmpeg: fix erroneous version comparisons

Comparing versions this way: (x.y < x1.y1) is obviously equivalent to
(x < x1 || (x == x1 && y < y1)), not to (x <= x1 && y < y1).

ffmpeg: use av_register_protocol2() if available

fixes usage with ffmpeg-0.8
