ffmpeg：与分段器一起使用tee

ffmpeg: Using tee with segmenter

我正在尝试使用T恤将我的流同时输出为1分钟的片段和文件。这是我的命令：

1
2
3

ffmpeg -i"rtsp://${cameraIp}:554/axis-media/media.amp?videocodec=h264&resolution=1280x720&fps=15" -c copy -map 0 \\
-f tee"[f=ssegment:segment_time=60:segment_format=mp4:reset_timestamps=1:r=15] ${rootPath}/${storeId}-${location}-%03d.mp4 \\
| /tmp/${cameraIp}.mkv"

分别(没有tee)两个输出都可以正常工作。因此，我既可以输出为分段文件，也可以输出为非分段文件。但是使用T恤我会收到以下错误：

[stream_segment,ssegment @ 0x217ece0] Failed to open segment '
/etc/cida/diagnostics/vid/780801-99-000.mp4' [tee @ 0x217d820] Slave
'[f=ssegment:segment_time=60:segment_format=mp4:reset_timestamps=1:r=15]
/etc/cida/diagnostics/vid/780801-99-%03d.mp4': error writing header:
No such file or directory

请参阅下面的完整命令输出。有什么建议吗？
