this is slightly obscure but still a bug so reporting it

the attached video has a chapter every 200ms

I can navigate through the chapters using the right click > jump to menu without problems but as soon as you select a chapter in the last second, MC moves the "selected chapter" tick to the last chapter hence this view is no longer correct

[mattkhan]

the Spears & Munsil UHD Benchmark contains many mpls and m2ts files, the playlists frequently contain a number of v short chapters which exist as individual m2ts files.

This presents a problem for playback by MC without using BD menus (i.e. importing individual items into my library) for 2 reasons

1) if I import the m2ts, there's no way to start playback in a paused state so playback immediately exits
2) if I import the mpls, MC is unable to reliably jump chapters (pick chapter x and it will move to a chapter greater than x)

here's an excerpt from one chapter list (after extracting as mkv)

Code: [Select]

[CHAPTER]
id=-8718111315209485041
time_base=1/1000000000
start=0
start_time=0.000000
end=375375000
end_time=0.375375
TAG:title=Chapter 01
[/CHAPTER]

in this example, if I pick chapter x then it consistently lands on chapter x+2

it would be good to fix both issues

[mattkhan]

an example

start playback
pause
jump to chapter 1 (aka position 0)

Code: [Select]

$ curl http://localhost:52129/MCWS/v1/Playback/Position                                                                                                                               
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<Response Status="OK">
<Item Name="Position">2739</Item>
</Response>


jump to chapter 3

Code: [Select]

$ curl http://localhost:52129/MCWS/v1/Playback/Position                                                                                                                               
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<Response Status="OK">
<Item Name="Position">751</Item>
</Response>

(but it shows chapter 5 in the list)

jump to chapter 1 again

Code: [Select]

curl http://localhost:52129/MCWS/v1/Playback/Position                                                                                                                               
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<Response Status="OK">
<Item Name="Position">1877</Item>
</Response>

on closer inspection I think the actual position is correct but the information reported from MCWS and via the UI is frequently wrong (MCWS only for chapter 1, the UI inc OSD at all times)

I'd forgotten I had previously raised https://yabb.jriver.com/interact/index.php/topic,136330.msg944415.html#msg944415 which seems likely to be a different manifestation of the same bug
