Transmission jitter after reconnection

[Morgan0328]

Hi when i pull and rebuild the srt-live-transmit.exe at 2020-09-07 version , my process doesn't work

Caller:
srt-live-transmit.exe udp://228.8.8.8:8888?adapter=169.254.24.188 srt://192.168.0.165:5101?adapter=192.168.0.171

Listener:
srt-live-transmit.exe srt://:5201?adapter=192.168.0.165 file://con | tsp --max-input-packets 7 -I file -P regulate --packet-burst 7 -O ip 227.7.7.7:9999 -l 192.168.0.165

the Caller side show the msg :

16:36:17.284000/T9036*E:SRT.ea: IPE: remove_usock: @425358004 not found as either socket or group. Removing only from epoll system.
13160 bytes lost, 32072236 bytes sent, 32085396 bytes received

what is that mean ? It work if i remove the adapter from Caller like
"srt-live-transmit.exe udp://228.8.8.8:8888?adapter=169.254.24.188 srt://192.168.0.165:5101"

The bitrate is stable if i run caller first and then start to receive the srt source at another computer ,
but if run Listener first the waveform of bitrate like sawtooth wave.
is it necessary to run caller first?

Thank you.

Hi @Morgan0328
Just to confirm, could you please also try to surround the URI with quotation marks like this

srt-live-transmit.exe "srt://:5201?adapter=192.168.0.165" file://con

The second waveform is When i Restart the Caller Side .

As I understand, there are two issues you are reporting:

1. The IPE message (addressed in [apps] Fixed stransmit processing a socket twice #1569). Does not seem related to the adapter URI option.
2. Some waveform you are seeing when you restart a caller? Could you please provide more information on this topic?

Note 1. In the following example, you are using UDP as a source. You don't need the target address as you won't send any data there.

srt-live-transmit.exe udp://228.8.8.8:8888?adapter=169.254.24.188

can be

srt-live-transmit.exe udp://:8888?adapter=169.254.24.188

Note 2. TSDuck has added support for SRT recently. This part can be reduced to just tsp. Refer to the TSDuck's docs.

srt-live-transmit.exe srt://:5201?adapter=192.168.0.165 file://con
| tsp --max-input-packets 7 -I file -P regulate --packet-burst 7 -O ip 227.7.7.7:9999 -l 192.168.0.165
