错误摘要：您好，我在 ubuntu 14.04lts 上使用 mininet 模拟器创建了一个网络。在这个网络中，我想在两个主机之间传输视频。我在发送方主机中使用 vlc，在接收方主机中使用 ffmpeg。当我运行 ffmpeg 时，我收到很多这些错误：
[avi @ 0x66c1900] Non-monotonous DTS in output stream 0:1; previous: 3497, current: 3480; changing to 3498. This may result in incorrect timestamps in the output file.
[avi @ 0x66c1900] Non-monotonous DTS in output stream 0:1; previous: 3498, current: 3481; changing to 3499. This may result in incorrect timestamps in the output file.
[avi @ 0x66c1900] Non-monotonous DTS in output stream 0:1; previous: 3499, current: 3482; changing to 3500. This may result in incorrect timestamps in the output file.
[avi @ 0x66c1900] Non-monotonous DTS in output stream 0:1; previous: 3500, current: 3483; changing to 3501. This may result in incorrect timestamps in the output file.
[avi @ 0x66c1900] Non-monotonous DTS in output stream 0:1; previous: 3501, current: 3484; changing to 3502. This may result in incorrect timestamps in the output file.
以下是使用的命令：
ffmpeg -i rtsp://10.0.0.1:8554/test1.sdp -acodec copy -vcodec copy /home/sana/lab/mrp/test1.avi
这是我的解答吗？我该如何使用它？
