在流 #1 中找不到编解码器 none 的标签,容器中当前不支持编解码器,输出流中的 DTS 非单调

在流 #1 中找不到编解码器 none 的标签,容器中当前不支持编解码器,输出流中的 DTS 非单调

我正在尝试使用命令行中的 ffmpeg 从我的 IP 摄像机流录制视频。

fmpeg -rtsp_transport tcp \
>  -i rtsp://192.168.0.250/stream1 \
>  -c copy \
>  -map 0 \
>  -f segment \
>  -segment_time 60 \
>  -segment_format mp4 \
>  "/home/video/stream-%010d.mp4"

并得到以下输出:

尝试了一些不同的选项,如 -c:v libx265 或 -c:v libx264,但不起作用,输出略有不同。但主要错误是相同的:

Could not find tag for codec none in stream #1, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

然后我尝试改变输出格式:

 ffmpeg -rtsp_transport tcp \
 -i rtsp://192.168.0.250/stream1 \
 -c copy \
 -map 0 \
 -f segment \
 -segment_time 60 \
 -segment_format avi \
 "/home/video/stream-%010d.avi"

它开始录制视频(录制了 2 个损坏的视频文件)但出现错误:

我尝试过:添加一些不同的键(一次一个)-fflags +genpts,,,,这些都不起作用。还尝试过输出视频文件-use_wallclock_as_timestamps 1,但它们都已损坏。我还能尝试什么来从 rtsp 保存视频?-thread_queue_size 512-vsync 0 -enc_time_base -1-reset_timestamps 1

答案1

流#0:1 是未知数据,但 MP4 复用器不知道如何处理它。

  • -map 0通过更改为 来仅映射视频-map 0:v
  • 或者-map 0通过添加来保留并省略数据流-map -0:d
