DCT 快速算法

linux下用ffmpeg解码库写的一个简单的视频播放器，原则上应能播放ffmpeg支持的视频格式，但仅能播放h.263视频，编译命令：g++ -g -o ffplay ffmp1.cc -L./libavformat -lavformat -L./libavcodec -lavcodec -L./libavutil -lavutil -lm -lz -ldl -L/usr/lib -lSDL -lpthread-linux using ffmpeg decoding the written a simple video player, in principle, be able to support the ffmpeg broadcast video format, but only broadcast h.263 video, compiled order : g-g-o ffplay ffmp1.cc-L./libavformat- lavfo rmat-L./libavcodec- lavcodec-L./libavutil- lavutil- lm- lz- ldl-L/usr/lib- lSDL- lpthre ad
