Fix compilation with Libav Doesn't define AVPROBE_SCORE_RETRY for some reason. They use AVPROBE_SCORE_MAX/4 directly internally. AV_DISPOSITION_ATTACHED_PIC is not defined with the most recent Libav release. AVIOContext.av_class exists in Libav, but is apparently disabled in old releases. Disable it for now until people stop torturing me with old crap releases. 2012-12-11 13:35:52 +00:00			`#include <libavformat/version.h>`

Improve compatibility with Libav 0.8.4 and ffmpeg 0.11.2 Libav 0.8.4 is ridiculously old (in relative terms), so I don't know how many things are broken silently. Encoding is disabled, because the required API hasn't been added yet. (On the other hand, the old API can't be used in newer versions.) This should improve compatibility with ffmpeg 0.11.2 as well, which didn't define AV_CODEC_ID_SUBRIP yet. 2012-11-14 01:31:57 +00:00			`#if (LIBAVUTIL_VERSION_MICRO < 100) \|\| (LIBAVCODEC_VERSION_INT < AV_VERSION_INT(54, 53, 100))`

build: make it work on somewhat older ffmpeg versions Tested with n0.10.4. All these version checks are rather tricky, because Libav and FFmpeg change the same thing at slightly different versions. 2013-01-31 16:41:29 +00:00			`#if LIBAVUTIL_VERSION_INT < AV_VERSION_INT(51, 36, 0)`
