ffmpeg 7.x There are no speed and time statistics if there are data streams in the SRT stream

[Denis Filippov]

Summary of the bug:
How to reproduce:
The stream from the TV-channel contains scte-35 tags and subtitles as a teletext. If you use the command for such a stream:

% ffmpeg -hide_banner -loglevel fatal -stats -i "srt://94.140.220.80:12108?streamid=571570#e05214d" -map 0:a -map 0:v -map "0:d?" -c:v h264 -c:a aac -f null -
ffmpeg version 7.1
built on Ubuntu 22.04

The result of statistic:

% frame=  393 fps= 34 q=13.0 size=N/A time=N/A bitrate=N/A speed=N/A

Stream data:

% Input #0, mpegts, from 'srt://94.140.220.80:12108?streamid=571570#e05214d':

Press [q] to stop, [?] for help

Without -map "0:d?" everything all right, result:

% frame=  361 fps= 34 q=20.0 size=N/A time=00:00:15.48 bitrate=N/A speed=1.46x

The problem is exclusively on versions starting from 7.0
Similarly, there are no problems with ffmpeg versions 5.x and 6.x.
I have tried all available Dockers as well as the local build on linux and macos - the result is similar: versions starting from 7 do not provide statistics with datastreams.

I can run the verification stream on demand. The stream is limited to 1 connection.
