總長度： _formatCtx->duration / AV_TIME_BASE;
當前frame的postion: avcodec_decode_video2(_videoCodecCtx, _videoFrame, &gotframe, &packet); float position = av_frame_get_best_effort_timestamp(_videoFrame) * _videoTimeBase;
當前播放百分比(0.0~1.0)： AVStream *st = _formatCtx->streams[_videoStream]; float start_time = st->start_time * _videoTimeBase; avcodec_decode_video2(_videoCodecCtx, _videoFrame, &gotframe, &packet); float position = av_frame_get_best_effort_timestamp(_videoFrame) * _videoTimeBase; float video_position = position - start_time; float video_duration = _formatCtx->duration / AV_TIME_BASE; float video_persent = video_position / video_duration;
