FFprobe terminates fine here with the sample you uploaded, what do I
miss?
Try removing "head" from the pipeline.
I probably shouldn't have included "head" in the command example, just
happened to be what I was doing while testing to try to see what was going
on.
$ ffprobe -analyzeduration 2G -i pgssub-ffprobe.infinite.loop.mpg
-select_streams s:0 -show_frames -print_format flat | grep pts_time | head
Even with the "head", notice all the pts_time values are the same, which
(at least to me) indicates something isn't quite right.
frames.subtitle.0.pts_time="2.685711"
frames.subtitle.1.pts_time="2.685711"
frames.subtitle.2.pts_time="2.685711"
frames.subtitle.3.pts_time="2.685711"
Also, try testing with the .m2ts example and use the "-show_streams"
option (instead of -show_frames). This is where you can see this error:
[pgssub @ 0x21f0de0] Unknown subtitle segment type 0x0, length 0
