The NVRs in this range support the latest H265 and H264 video compression formats, including the latest advanced versions, to get the highest performance out of any Onvif IP camera. If your cameras support H265, the most efficient codec available today, they will work great with these NVRs...
首先用函数avcodec_find_encoder()查找编码器;然后用函数avcodec_alloc_context()申请CODEC,函数avcodec_alloc_frame()申请编码器中的图像帧空间;设置编码器参数,包括宽度、高度等;avcodec_open()打开编码器CODEC;获取图像数据;编码当前图像avcodec_encode_video();写入码流文件;编码完毕后,销毁各种资源,关闭编码器avcodec...

Step 3:Tap the "Codec Option" icon and a window pops up. The resolution, frame rate, bit rate, aspect ratio, as well as audio settings are all adjustable. Change your HEVC high settings to middle level to lower down the computational preassure for your PC. ...
