Apparently the parser ignores the input size, just like you ignored my
recommendation for tsparse configuration. Anyway ...

# Transmitter
gst-launch-1.0 filesrc location=my.ts ! \
  tsparse set-timestamps=1 smoothing-latency=40000000 ! \
  chopmydata step-size=188 min-size=188 max-size=1316 ! \
  srtsink uri=srt://:8888

# Receiver / Player
gst-play-1.0 srt://127.0.0.1:8888

File source has an option to configure the read size, these needs to be multiple of 188 and max to 1316. The ts parse as an option to add and smooth timestamp, these need to be configured.
