MythArchive animated menus: thumblist does not define thumbnail videos.

[J.Pilk@…]

As a one-off I wanted custom chapter points. Usually I never look at them. The non-animated ones look fine, and chapter selection works.

mythburn.py, line 3186, --thumblist < starttime, which looks (to me) like a constant here - although the thumbnail videos don't all look the same. My log has an exit-status error here, too.

Extract from progress.log. code 34 is probably spurious (#11547) and I suppose 661 might be a node identifier. Only one instance of this message in the log, triggered by the status failure.

Using user defined thumb images - 00:00:45,00:11:46,00:22:47,00:33:50,00:44:53,00:55:54,01:06:52,01:17:54

13:13:49 mytharchivehelper failed with code 34. Command = mytharchivehelper -q -q --createthumbnail --infile "/home/John/arctmp/work/1/stream.mv2" --thumblist '661' --outfile "/home/John/arctmp/work/1/preview/preview-i1-t%1-f%2.jpg" --framecount 250

13:14:34 Added image /usr/share/mythtv/mytharchive/themes/MythCenter_-_Animated/preview-frame.png

There were four recordings, eight chapters each.

log with mythburn.py patched to show commands generated:

22:51:44 Using user defined thumb images - 00:00:44,00:11:46,00:22:47,00:33:52,00:44:52,00:55:54,01:06:52,01:17:54 22:51:44 mytharchivehelper -q -q --createthumbnail --infile "/home/John/arctmp/work/1/stream.mv2" --thumblist '0' --outfile "/home/John/arctmp/work/1/preview/preview-i0-t%1-f%2.jpg" --framecount 250 22:51:48 mytharchivehelper -q -q --createthumbnail --infile "/home/John/arctmp/work/1/stream.mv2" --thumblist '661' --outfile "/home/John/arctmp/work/1/preview/preview-i1-t%1-f%2.jpg" --framecount 250 22:51:53 mytharchivehelper -q -q --createthumbnail --infile "/home/John/arctmp/work/1/stream.mv2" --thumblist '1322' --outfile "/home/John/arctmp/work/1/preview/preview-i2-t%1-f%2.jpg" --framecount 250 22:51:59 mytharchivehelper -q -q --createthumbnail --infile "/home/John/arctmp/work/1/stream.mv2" --thumblist '1983' --outfile "/home/John/arctmp/work/1/preview/preview-i3-t%1-f%2.jpg" --framecount 250

... and so on. Thumblist sequence is 0, 661, 1322, 1983, 2644, 3305, 3966, 4627; this seems to be the autogenerated one.

How can it be changed to being defined by the thumblist?

[J.Pilk@…]

unified diff from my modified version of mythburn.py for 0.26-fixes.

[J.Pilk@…]

This patch has worked for me. User-generated markers have the format u'01:06:52', auto-generated markers don't have the 'u'. I don't know if this is intentional. Both seem acceptable.

[J.Pilk@…]

I think this patch, which does work, ought to be accompanied by a sanity check; thumb markers increasing, first > 0, last at least 10 s before EOF. If not true dvdauthor will probably fail. The check could and should be done much earlier, and the thumblists ought to be non-volatile in case of job failure. FRWOP, I'm afraid. Just a warning.

mythburn.py: fix animated chapter menu when using user defined chapters

The animated chapter menu was never updated to take into account user defined
chapter points so was always using the fixed chapter points.

Fixes #11704.
