Chapter Images

[quickmic 1703]

Hi

Emby server, latest beta version:

Seems there is a bug in chapter "ImageTag"

Auto generated chapters (episodes):

'Chapters': [{'StartPositionTicks': 0, 'Name': 'Chapter 1', 'ImageTag': '3b2e252361fdd24e3157ffdea3840292'}, {'StartPositionTicks': 3000000000, 'Name': 'Chapter 2', 'ImageTag': '3b2e252361fdd24e3157ffdea3840292'}, {'StartPositionTicks': 6000000000, 'Name': 'Chapter 3', 'ImageTag': '3b2e252361fdd24e3157ffdea3840292'}, {'StartPositionTicks': 9000000000, 'Name': 'Chapter 4', 'ImageTag': '3b2e252361fdd24e3157ffdea3840292'}, {'StartPositionTicks': 12000000000, 'Name': 'Chapter 5', 'ImageTag': '3b2e252361fdd24e3157ffdea3840292'}, {'StartPositionTicks': 15000000000, 'Name': 'Chapter 6', 'ImageTag': '3b2e252361fdd24e3157ffdea3840292'}, {'StartPositionTicks': 18000000000, 'Name': 'Chapter 7', 'ImageTag': '3b2e252361fdd24e3157ffdea3840292'}, {'StartPositionTicks': 21000000000, 'Name': 'Chapter 8', 'ImageTag': '3b2e252361fdd24e3157ffdea3840292'}, {'StartPositionTicks': 24000000000, 'Name': 'Chapter 9', 'ImageTag': '3b2e252361fdd24e3157ffdea3840292'}], 'MediaType': 'Video'}

As you can see, imagetag reported is always: "3b2e252361fdd24e3157ffdea3840292"

I assume this should not be the case. Guessing this should be individual screenshots according to timestamp.

 

btw, feature request: As Kodi has no functionality to disable embedded (videostream) chapter extraction, I need to know what is native coming from video and what's generated.

Currently I use modulo StartPositionTicks from Chapter >1 as a reasonable guess and some other magic, but actually would be great if this can be reported in some way.

Is there an actual problem?

[quickmic 1703]

Well yes, I got the same image everywhere. -> for all chapters

 

 

[quickmic 1703]

Maybe I'm not clear enough.

The data (first post) is a selection of the return value from  Emby server after item query with extra fields -> "chapters".

Right but when you request a chapter image, the chapter index is part of the url, therefore making each of them different. Can you get this to happen with a brand new video in the library?

Thanks, will check.

That solved the issue, thanks for you help. -> I though "ImageTag" should be unique, but actually the index was the problem.
