This interpretation is correct:

In my understanding you still need the x-axis defined. I did this with the column id.

Here is the provided data which I took from your example:

IP cameras are of varying quality, some behaving erratically in my experience. Dealing with their RTSP streams requires a dose of fault-tolerance.
This appears to be a byproduct of the low-end of the CCTV industry playing fast and loose with standards, RTSP and ONVIF being the two most frequently abused. Fortunately, you can usually work around these problems. Unless your IP cameras and controller are all designed to play nicely together, only use ONVIF for once-only discovery and settings management.

After struggling I started comparing the RTSP/SETUP messages between openRTSP and ffmpeg. openRTSP by default already outputs a lot of verbose diagnostic.

openRTSP

openRTSP sends the commands OPTIONS, DESCRIBE and then SETUP. The SETUP messages were:

Many pandas functions do not modify the df it is called on, but return a modified df. Generally you should either use inplace=True argument if available, or use

rsync already has internal checks for data integrity, you just need it to "tell" you it completed, for example by adding && echo transfer complete

If the message is not displayed, it may have failed and the transfer did not complete. If you want to display a message when it fails instead, it's also possible with || echo transfer failed

If you want both, the cleanest way is to use an if construct:

In other words: According to RTP protocol, is sending back the packet can work, or do I need to reconstruct them?

You need to construct a dedicated RTP header and add the received payload. SSRC and timestamp must be generated in a meaningful way or the receiver may discard those packets.

You can use sapply over each value of Turns_split and get the index where current word is 'ta' and previous word is 'got'.

You should use the -alaw format instead. And it will work for you.

While not directly answering the question I used gstreamer to convert multicast to unicast as a workaround:
