利用ffmpeg 获取USB 或者本地摄像机视频,并将视频编码后保存本地文件或者发送到远端流媒体服务经常会出现 类似real-time buffer [USB2.0 Camera] [video input] too full or near too full (101% of size: 30412) 这样的错误,其根本 原因是编码的速度太慢导致过多的图片数据保存在缓存内,缓存区空间太小或满...
实时缓冲区(Real-time Buffer)是指在处理实时数据流时,用于临时存储数据的一段内存区域。在视频监控系统中,集成摄像头捕获的视频流会首先进入实时缓冲区,然后再进行处理和传输。 相关优势 平滑处理:缓冲区可以平滑数据流的波动,确保数据处理的连续性。 错误恢复:在网络不稳定或数...
