Downloading Subtitles

[CJB]

Please - is there a way of downloading subtitles after the respective
video file has been downloaded? The latter file is a large one and I
don't wont to download it again. But trying to watch the video the
sound is not clear. The pid is b0bkvw2l BTW. Many thanks. Chris B.

Until recently subtitles were downloaded first thus get_i pvr could be
stopped once done.

Now they are downloaded after video. Why?

--subtitles-only

Don't know what happened there..... it should have read:

That's how I do it -- just yesterday afternoon in fact. Took me a while
because I forgot to check --long-help which is off where the option is
hiding.

get_iplayer --subtitles-only --pid b0bkvw2l

Huh - never could get used to the Ozzie accent!!!

I've never actually used subtitles, but there's no mention of --subsonly
on the page I linked to. I assume it's been superseded by
--subtitles-only.
Actually the link at
https://github.com/get-iplayer/get_iplayer/wiki/subtitles#examples
takes you straight to the Example section of that page. I posted the
wrong link in my first message although it does go to the correct page.

In case anyone wants to know how to actually use a separate subtitle
(.srt) file, the instructions for using one (in VLC) are here:

... Because the powers that be (i.e. the one and only
person still maintaining the code of GiP) decreed so:

https://github.com/get-iplayer/get_iplayer/commit/35d8e7b4d23815b85937727868bd9364ae829f0a

The logic behind that change appears to be

> # Get subtitles if they exist and are required and media download
> succeeded

i.e. the author ASSUMES you wouldn't want the subs
(only) if the actual media download failed...

The status quo ante was:

> # Get subtitles if they exist and are required
> # best to do this before streaming file so that the subtitles can be
> enjoyed while recording progresses

In any case, even back when the subs were fetched
before media download completion, they still had
the ".partial.srt" suffix and that was only removed
when the video itself was fully dumped to file...

And it wasn't a "recent"change, 't was more than a year ago...
(... I couldn't help noticing the comment
to the aforelinked commit:

https://github.com/get-iplayer/get_iplayer/commit/35d8e7b4d23815b85937727868bd9364ae829f0a#commitcomment-25039704

which, of course, remains unanswered to this day...)

Hi Vangelis

That is not quite the whole story. There were a few programmes whose
subtitle XML files (TTML?) were corrupt. They included some NUL
characters and, I am told, NUL is not a valid character in XML.

The code was changed to ignore NUL characters. As an additional measure
downloading of subtitles was delayed until the end to reduce the risk
that errors in subtitles could cause the whole download to fail.

Best wishes
Richard

I haven't got it quite right either. The 3.07 release notes say,

"Fixed a bug that caused get_iplayer to exit (and skip metadata tagging)
when corrupt subtitles were provided by the BBC. Corrupt subtitles will
now generate an error message, but get_iplayer will not exit. As an
extra precaution, subtitles download now occurs after tagging is complete."

They also say,

"Subtitles are now trimmed according to --start and --stop, if
specified. The actual subtitles start and/or stop times are calculated
to the nearest chunk boundary in the HLS or DASH stream. The value of
--suboffset is still applied. This trimming is not supported for
--subtitles-only. You can use --subtitles-only to re-download the full
subtitles for a programme if desired. (@notnac)"

I am guessing, but it is possible that a change in download order was
needed to implement that.

The 3.09 release notes say,

"Null characters are now removed from subtitles before processing. This
should prevent at least some problems caused by corrupt subtitle files.
(@notnac)"

Best wishes
Richard

According to

https://github.com/get-iplayer/get_iplayer/blob/57ac0a5b92c926277d53d591e0d46659321583e2/get_iplayer#L144

--subsonly should still be valid!

(As should be

--subtitlesonly
--subs-only )
