I tried again as an experiment this morning. This time with a start at
2:45:00 as the previous try had provided me with the section from 2h to
about 3h. The program was (apparently) about 4h15m long so this should have
got me a file about 1h30m long.
I left this running in a xterminal window as I did something else. When I
checked some time later I was getting a looping error
File contains neither video or audio exit code 1 (raw code = 256)
So I did a ctrl-C and shut the terminal, then looked at the resulting flv.
As came, it will play with VLC, but as with earlier results, showed the
wrong duration and would crash out if I tried to jump to a later section
whilst playing. I guess this may be the norm for the raw flv's?
So (as before) I ran the flv though ffmpeg with codec copies into an mp4.
This says it is 1h18m long, and plays OK, inc being able to jump to a
different point in VLC. Seems to cover up to the end result. It seems
slightly shorter than I'd expected but has what is required.
Makes me continue to think there is something odd about this programme file
which confuses gip. One curious point is that both the earlier attempt and
this one gave a file whose playable duration was about 1h18m, but from
different start points. Maybe a coincidence?
Other programme files I've fetched recently seemed fine.
