我试图通过rtmp向我的家人提供rtsp直播电视流，因为Fritz Box（提供流）只有4个调谐器 - >最多可以同时观看4个流。我使用ffmpeg将流准备为短划线流并将其发送到我的rtmp nginx。当我运行ffmpeg时，我在最后一个流中遇到了沉重的图像和音频伪像，并在控制台中出现了厄运的错误。我在google上找不到任何针对我案例的内容。我在互联网上看到AVM几乎没有实现rtsp protocoll足以让它与vlc媒体播放器一起工作。

反正有控制权吗？原始流在vlc上运行良好，但在ffmpeg之后无法查看。
编辑：我在我的Windows机器上运行/测试这个，但我的目标是这个任务是一个ubuntu 16.04所以这里ffmpeg在目标上有pthread支持：
